Flaring brake pipes is a process that may be needed at any time by someone who has a personal car. Of course, the implementation of this and any other procedure associated with technological service and vehicle repair can always be entrusted to competent service station professionals, however, numerous drivers go the other way and strive to do everything with their own hands. Any owner has the right to decide who to trust with the maintenance of his vehicle, while many of the problems can be fully resolved on their own.
Purpose of brake pipes
To have a clear picture of what they are needed for and what function they perform brake pipes, they should not be regarded as an independent component, you should get acquainted with the entire system of the car. The automobile braking system functions in this way: if it is necessary to reduce speed or during sudden braking, the driver unscrews the corresponding lever, and the piston, which is under great pressure in the main cylinder, begins to drive the liquid away in special ways.
The braking itself or the absolute stop of the car takes place at the moment of the reorganization of the forces of the fluid pressure on the wheel cylinders in opposition to the brake pads. So, the paths along which the piston drives the fluid to the wheels consist of tubes and hoses. Exiting the part mode leads to a malfunction of the entire braking system, and your car becomes unusable.
Tube malfunctions
With poor transmission of fluid through the tubes, the braking of the car is delayed, and the braking distance almost doubles. In addition, in the operation of the system, most often when the brake pedal is pressed, extraneous sounds and some impulse movements occur.
The cause of tube damage is loss of fluid in the brake system. This loss will lead to overheating of the brake drums and uneven pad wear. Another indicator may be the unusual behavior of the car during the period of pressing the lever, namely: the car moves a little to the side. Of course, this is not a direct cause, however, as professionals say, it may indicate a breakdown of the tubes.
Each motorist should be a little familiar with the design of his own car in order to be able to eliminate the breakdown with his own hands in the event of repair work, if possible. This applies in particular to the autobrake system. Often, when it malfunctions, it is necessary to expand the pipes through which the liquid passes, when the lever is pressed, from the cylinder to the pads.
You can determine the breakdown yourself in the following situations:
An obvious sign that the tubes are worn out and it's time to flare will be an increase in stopping distance.
The noted problems cause very high damage not only to individual components, but also to the whole system. If the owner wants to protect the car from problems, he needs to remember that he should at least once a year undergo testing of the auto-brake system.
Pipe flaring is not a particularly pleasant job, but it is not very difficult either. The most important thing is that you can flare with your own hands. For high-quality performance of this work, it is necessary to buy a special device called a "flaring tool".
Such a tube flaring kit has an affordable price, and you can see in it:
- pipe cutter;
- union;
- ticks;
- stamps.
You can buy a kit at any car shop, its cost is a penny compared to the cost of working at a service station.
When purchasing a flaring tool, you need to focus on the manufacturer and cost. It is better not to purchase the cheapest kits, as their quality does not contribute to long-term operation. This method of repair work will cost less than in a car repair shop.
Utilities are considered the culprit for unscheduled wear of pipes. Various chemicals and salts, generously sprinkled to fight, for example, with ice, several times stimulate the rusting of the alloy and reduce the duration of the work of numerous elements released by the manufacturer. And one more factor that makes you often deal with the brake system is the infamous domestic roads. Under load, the tubes deform and burst. All together leads to the fact that the components fail quickly.
Self flaring
A cheaper way is to manufacture a home-made device, and not to purchase a kit for flaring brake pipes. With the desire and the minimum ability to work with your hands, there is nothing difficult in this. First you need to make a base (frame) for attaching parts. You can make it from two metal corners. Cut the corners of the required length with a grinder, drill 2 holes in them for bolting. This is done in 15 minutes.
Having assembled the frame, it is necessary to make holes for the tube and remove the chamfers on a drilling machine or drill. The most difficult is the production of punches (mandrels). You can order them to a turner.
If you decide to purchase a flare kit, don't go for the cheapest alternatives on the market. Yes, you can take devices for 800 rubles, but they will most likely be disposable parts. It has been determined that a more or less high-quality tube flaring kit cannot cost less than 2,000 rubles, or even more.
Often the body of the tube remains intact, but the structure of its head is destroyed. There may be other types of damage:
- thread coking as a result of liquid getting on it;
- contamination of connections, etc.
In such situations, if the length allows, you can simply cut off the defective part with a special tool. You can change the entire tube if you implement the next repair.
Work order
Having figured out how to flare pipes yourself, provide yourself with a minimum amount of similar work in the future. To do this, install a copper tube in a special place. We assure you that you will need to remember about flaring much less often. Even with a very active operation of the machine earlier than after 3 years, you will not need it.
Pros and cons of self-flaring
The advantages of self-flaring can be attributed to that you don't have to pay someone to work.
Of the minuses, it should be noted that your mechanism may be needed only once. The exception is if you buy used cars with high mileage that were in bad, negative circumstances or were in accidents, and change them quite often.
To make repairs according to the instructions yourself or to entrust professionals, you have to decide personally, however, it is necessary to constantly monitor the condition of the entire brake system and pipes.
So, summing up, it can be noted that the work of expanding pipes is not very time-consuming and complicated. You need to understand that most of the repair work of a steel friend can be easily done on your own. And this is very significant, because by fixing a malfunction with your own hands, you can not only save money, but also do the job better than any car mechanic. The main thing is to follow the instructions.
Independently and will help in the repair of the brake system.
In order to make rolling for brake pipes with your own hands, you will need:
* Bench vice
* Angle grinder, cutting and grinding wheel
* Metal corner size 100 mm
* Metal plate 6mm thick
* Drill for metal with a diameter of 4.5 mm, 6 mm, 10 mm
* Bolt from car hub
* Welding machine, leggings, welding mask
* Safety glasses, gloves, earmuffs
* Copper tube with a diameter of 5mm
* Lathe for metal, tooling
* Tap with thread M6 and M12
* Can of matte paint
* Electric drill
Step one.
He clamps a metal corner measuring 100 mm in a vice and, using a ruler and a pencil, we make markings along which it will be necessary to saw off the workpiece.
We mark about 30 mm from the edge of the corner and saw off with the help of an angle grinder with a cutting wheel installed in it. When working with an angle grinder, follow safety measures, wear safety glasses, headphones and gloves, and also do not forget that a power tool can escape from your hands at any time, so you need to hold it tightly.
Next, we fix the corner in a vice and align the ends with the help of an angle grinder with an emery wheel installed for grinding, we also slightly round the edges so as not to get hurt when working with the tool.
After that, we change the position of the workpiece in a vice and also grind it, removing rust and other external defects of the part.
The result is a surface like this.
Step two.
We install the part on an anvil or vise and make a center punch in the middle with a light hammer blow on the core.
In this place, we drip a little technical oil and drill a hole using an electric drill, in the chuck of which a metal drill with a diameter of 5 mm is installed, after that we change the drill to 10 mm.
In the process of drilling, do not forget to add technical oil, as this will reduce the degree of wear of the cutting edge of the drill, which will extend its service life. In the finished hole, we cut the thread with a tap, in this case the thread is selected depending on the diameter of the bolt, here an M12 bolt from the car hub is used. When cutting threads, it is also important to add lubricant.
Step three.
We measure the required length for attaching the tube and saw off a part from the corner with an angle grinder.
Next, we clamp two metal blanks that need to be made from a sheet of metal 6 mm thick, they need to make a hole in the middle so that half of the diameter falls on one blank, and the rest on the other. In this case, we take a drill with a diameter of 4.5 mm, in the future it is possible to make various plates with the necessary grooves for any diameter of the tubes.
After that, you need to drill holes in two blanks at once for mounting on the corner, for this we clamp them together with a hand vise, and only then we drill holes, first 4.5 mm, and then 6 mm with a drill for metal.
Step four.
To be able to roll the tubes, you need to do the processing of the hub bolt. To do this, we first shorten it with an angle grinder, and then clamp the bolt in the three-jaw chuck of a metal lathe and make a groove to a diameter of 2.5 mm, by the way, it is equal to the inner diameter of the copper tube.
For rolling, we grind a small recess under the hat. In the end, the bolt should look like this.
You need to weld a bar to it, for this you need a welding machine. When working with the welding machine, be careful, and also use personal protective equipment, a welding mask and leggings.
In order for the tube not to bend during the rolling process and to roll evenly, it is necessary to make a centering.
We take the brake tube and put it on the tip of the bolt, then we install a workpiece under it with a groove for the tube, and then we fix it with a hand vise and begin to outline the drilling locations.
After that, we open the hand vise and drill holes to the end with a drill whose diameter is 5 mm, and then we cut the M6 thread in these holes with a tap.
Step five.
Now it remains to give the tool a beautiful look, for this we paint the details with a can of hammer paint, having previously protected the thread with masking tape.
The tool is completely ready, which means it's time to test it in action. August 4, 2019
Responsible motorists know that they need to regularly monitor the condition of their car. Especially keep under control the operation of the brake system. Brake pipes play a significant role in it. If you notice that they have damage, then it's time to fix them. Often flaring is enough for this. Do not doubt your abilities, but read the article carefully. Following simple instructions, you will cope with the problem without the services of a car service.
Purpose and functions of brake pipes
Brake pipes are not a separate element, but an important component of the whole system. They create a kind of highway through which the brake fluid moves. Their proper operation is required when reducing speed, stopping the car and, of course, emergency braking.
The main function of the tubes is to ensure the movement of the working fluid to the elements of the brake system. During this work, they are constantly subjected to high pressure and hydraulic loads. If they fail, the operation of the entire mechanism is disrupted, and the vehicle becomes unusable.
When is brake piping required?
Long-term operation of the car, the ruthless use of the "iron horse", untimely technical inspections and neglect of the rules of care lead to problems, including with brake pipes. They have:
- throughput decreases.
- cracks and rust appear;
- the fastening weakens or rots;
- carving turns sour;
- break occurs.
All this will certainly lead to the failure of the entire braking system as a whole. So, there will be a threat of an emergency situation on the road.
The correct solution would be the flaring of the tubes, that is, the elimination of the directly damaged area. It is not always necessary to change the entire tube. If the length allows, you can only get rid of the damaged part. But don't forget the old saying, "Measure twice, cut once."
Reference! Flaring of brake pipes is applied only to metal products. Rubber materials must be replaced entirely.
Alarm bells about a malfunction of the brake system, including brake pipes, are:
- leakage of brake fluid;
- extraneous sounds, squeaks when pressing the brake pedal;
- uneven pad wear;
- free movement of the brake pedal;
- increase in braking distance;
- overheating of the brake drums;
- when braking, the car pulls to the side.
Important! Ignoring alarming symptoms can lead to both a breakdown of the entire vehicle and serious consequences while driving.
Instructions for self-flaring
Not every motorist is tempted to do repairs. For some, this is too difficult, while others do not have the time and desire. If you belong to the listed categories, you can always contact a car service and entrust the flaring to professionals.
There is another factor that can stop you - this is the lack of a special tool. However, it can always be purchased at an automotive store or ordered online. The tool works with metal as carefully as possible, while maintaining the uniformity of the wall thickness and the smoothness of the inner surface.
If desired, you can easily purchase a flaring kit. There, in addition to the "flaring" includes:
- pipe cutter;
- ticks;
- clip;
- union;
- stamps for different diameters of tubes.
Important! Do not rush to purchase the cheapest sets. Basically they are of poor quality. It is better to pay a little more, but the life of the tools will be longer.
If the listed obstacles do not scare you, and you have everything you need at hand, do the repairs yourself. The process of expanding the brake pipes is not laborious and does not take much time. At the same time, after successfully completed work, you will definitely feel a sense of pride in your own capabilities.
Follow the instructions carefully:
- Drive the car into a viewing hole or overpass, immobilize.
- Prepare a flaring kit, you will also need a drill and some gasoline.
- Unscrew the brake pipe from the caliper or brake cylinder. Assess the degree of damage and the possibility of repair.
- If you can remove the damaged piece while still maintaining the correct length, cut it with a pipe cutter and discard. He's already done his job.
- Treat the correct cut edge with gasoline.
- Pliers clamp the tube to create a connector for the fitting.
- With a drill and a drill of the desired diameter, chamfer along the edges of the tube.
- Clear the tube from chips and insert the fitting.
- Take a flaring tool and insert a tube into the desired hole. It is necessary that its end protrudes 5-6 mm beyond the edge.
- Clamp the tool. At this time, the necessary part is processed by the mechanism.
- Admire the result of the work. At the end of the tube, a neat expansion should be obtained, which will hermetically connect the elements of the system.
- Install all parts in place. Fill the brake fluid and bleed the system to remove all air from it. Test the car.
Pros and cons of expanding tubes with your own hands
The flaring process itself will not take much effort, but, as in any business, you can highlight your positive aspects and disadvantages.
The advantages include the following facts:
- no need to pay for the work of strangers, and this is a profitable savings;
- you are interested in the serviceability of your car, so you will do the work responsibly and efficiently;
- no special knowledge and special skills are needed, which means that you will 100% cope with the task;
- you can do repairs at any time convenient for you, and you will not adapt to the working hours of a car service.
The cons are:
- the need for a special tool for the procedure;
- perhaps imperfect execution of flaring compared to experienced craftsmen;
- the uselessness of the tool after the work. It is only useful if you regularly deal with used cars.
You can try to repair a car with your own hands, and if in doubt, entrust it to specialists. You decide!
Prevention of breakage of brake pipes
Naturally, in order not to spend a lot of time looking for breakdowns and repairs in the future, it is best to treat your vehicle with care. Do not be lazy, but follow simple tips:
- Periodically inspect the brake pipes for rust and defects. Pollution, microcracks, corrosion lead to incorrect operation of the system.
- Change the brake fluid according to the regulations.
- Check tightness of fasteners.
- Treat surfaces with anti-corrosion agents.
- Avoid leakage of brake fluid.
- Become a supporter of careful driving. It is not uncommon for tube ruptures to occur when overcoming obstacles.
- Diagnose the brake mechanism at least once every two years. Motorists who spend a lot of time on the road should do this after every fifty thousand runs.
- Regularly monitor the wear and tear of vehicle parts, and it will take care of your safety.
For a vast army of motorists who are accustomed to doing car repairs on their own, the appearance of new tools and devices in the arsenal of existing ones is a self-evident inevitability. Today we will talk about repair, which very often requires the replacement of brake pipes. These elements are more exposed to external factors than others, which affects their condition. But it is possible to replace them only if there is a specialized tool with which the tubes are flared. No tool - this operation will fail. This means that you still have to go to the nearest car service. Or go to a car shop to become the owner of another very useful device.
Purpose of brake pipes
Any hydraulic system needs lines through which fluid is supplied to the working mechanisms. The braking system of a car is no exception, but it has its own characteristics. They are connected both with the design of the brakes and the technical characteristics of the working fluid used, to which very stringent requirements are imposed:
- it should not boil at temperatures exceeding 200 degrees;
- do not lose fluidity in forty-degree frost;
- not be aggressive to the rubber parts of the brake system;
- not lead to corrosion.
The last point is especially important for brake pipes, which are an integral part of the vehicle of a modern car. Consider the principle of operation of a typical braking system.
The vehicle stop algorithm is associated with the following actions:
- the driver, if necessary, to reduce the speed of the car until it stops completely, presses the brake pedal with the appropriate effort;
- the pedal rod directly acts on the piston of the brake master cylinder, bringing it into action;
- the piston, moving in the cylinder, acts on, creating a certain phenomenon;
- liquid, the compressibility of which is close to zero, moves along the highway and acts on the brake cylinders located on each of the wheels;
- The pistons transmit the momentum to the brake pads, which, pressing against the discs, create a braking force, slowing down the rotation of the wheels.
In this chain, the brake pipes are an integral part of the hydraulic line through which the working fluid moves. Their task is to prevent leakage of the TJ, therefore the quality of their connection with other elements of the brake system is of particular importance. For this, a technological operation called flaring is used.
Its essence lies in the deformation of the end section of the tube in such a way as to uniformly increase its diameter (the opposite operation, which consists in narrowing the diameter of the tube tip, is called rolling). Flaring is needed in order to ensure the most tight connection of the tubes to each other or the tube to the manifold.
Since, as we have already noted, the brake pipes are subject to mechanical stress, they can get damaged, causing the system to depressurize - in this case, an immediate operation is required to replace them. Normal wear and tear is the more common reason for replacing this brake system component.
The procedure for expanding the tube itself consists of three stages:
- definition between the tube sheet and the tip of the tube;
- flaring of both tubes and tube sheets;
- removal of the damping load from the inner walls of the tube.
The deformation technology requires that the metal of the brake tube is subjected to the so-called plastic deformation, and the metal of the grille is subjected to elastic deformation. To ensure this condition, the grating is made of a harder metal, which allows, after the expansion stage is completed, the tube grate completely “grasp” the tube.
Ensuring the required tightness of such a connection is carried out by applying the contact pressure method formed between the outer surfaces of the contacting parts. In some cases, the technology for connecting flared pipe ends involves the use of welding - this method is called combined.
In the factory, flaring is carried out using a special machine equipped with a hydraulic, pneumatic or electric type drive, which provides for the possibility of controlling the rotation speed. It is up to the drive to ensure the required reliability of the connection.
When replacing brake pipes, flaring is carried out using a special tool that can be purchased at an auto shop.
When flaring of brake pipes is required
Brake fluid, which ensures compliance with a number of the above requirements, has a high hygroscopicity, that is, the ability to absorb moisture. This is a retribution for a unique set of characteristics, which is why the complete tightness of the line is so important. is fraught with the fact that under the influence of high temperature it significantly increases the compressibility of the liquid. And this means that pressing the brake pedal will lead to the actual braking with some delay, which is unacceptable for reasons of traffic safety. And the more air there is in the system, the more noticeable the delay will be.
Depressurization manifests itself with quite definite symptoms - a significant increase in the braking distance, pedal failures and the appearance of extraneous sounds during braking.
Fluid leakage is usually accompanied by overheating of the brake drums, since the boiling point of the fluid diluted with air drops markedly. As a result, the brake pads begin to wear out more intensively and, which is especially unpleasant, unevenly.
Another clear sign of a violation of the integrity of the brake line is the departure of the car during braking from the original trajectory.
Note that the breakdown of the brake pipes (or rather, the need to replace them) can be caused by other reasons:
- deformation and cracks of the hexagonal head;
- clogging of threaded connections;
- coking of the brake fluid at the interfaces.
Not a single car is immune from such troubles, therefore it is so important to periodically (at least once a year) test the braking system as a whole. Diagnostics of the components of the brake line should be carried out every 50, routine replacement of rubber hoses and tubes is carried out every 125 thousand kilometers, regardless of their condition.
And since the replacement of these elements requires special processing, we will consider how to flare the brake pipe with our own hands and what tools will be required for this.
Self flaring
In industrial conditions, special high-strength shafts are used for expanding pipes, while the profile of the pipe end is formed as a result of their repeated rolling. Such a rolling machine allows you to perform the deformation as accurately and evenly as possible.
When self-flaring, they usually use kits that can be purchased online or in specialized stores. Such a kit includes a pipe cutter, a clamp, as well as dies with holes of different diameters (with metric or inch sizes) for flaring using a cone screw.
Many car owners, in order to expand the brake pipe at home, use a more primitive method that does not require the purchase of the device described above - a conical blank with the desired angle. If the tube is made of copper (these are not often seen now - manufacturers are massively switching to metal in order to save money), it has sufficient plasticity to perform such an operation on its own. But you will need not just strength, but precisely dosed efforts when pulling the tip of the copper tube onto the cone. Any skew upon impact - and the result may be unsatisfactory: from breaking the rolled surface in the place where the stronger impact fell, to jamming a surface that is too thin with such a surface treatment. So this method can hardly be recommended as acceptable - it should be resorted to only in case of emergency.
Much more predictable results are obtained when using an expander. Here you will also need to use physical force, but the process itself is simplified, since the pipe is pulled onto one of the interchangeable nozzles using a rotating handle.
The expander allows you to flare the tube to the desired diameter quickly enough, in just one approach, but even here a 100% result is not guaranteed. The key to success is the quality of the tube itself. If it is bad, that is, the walls are not perfectly even (they have different thicknesses in a certain area being processed), then in this case, thin walls will stretch more, thick ones less, and as a result, the flaring will turn out to be not ideal. Attempts to "squeeze" the connection can end in failure - it breaks or collapses.
The classic tool for expanding brake pipes is a set of rollers made of carbide materials. The rollers are rolled over the surface of the processed pipe, each time with increasing force. As a result, flaring is performed smoothly, and all the troubles that are typical for more primitive tools are impossible here. Each new revolution of the rollers increases the diameter of the workpiece by a minimum amount, and such a gradual stretching is very well tolerated by the metal.
A similar method is applicable even to a non-ideal workpiece, since in the presence of sections with thicker walls, they are rolled out to the required size, while the surface of the tube becomes even and smooth, without any defects and roughness.
Another common flaring method is the use of a solid-state cone, which is pressed with a certain force into a tube previously fixed in a vise. The quality of this method is comparable to the use of shafts, but here it is important to dwell on exactly the pressing depth that corresponds to the desired flaring diameter.
Of course, the ideal solution would be to purchase a ready-made factory-made machine. But if you belong to the category of craftsmen who try to do everything on their own, including rarely used tools, a copper tube flare can also be made at home. Without this tool, it will not be possible to ensure a reliable connection of the brake pipes.
The main condition is that the metal blanks must be durable, this will allow the device to be used for decades. The design of such a flaring machine is quite simple - it is a frame made of two equal-sized corners.
We will need the following tools and materials:
- drilling machine;
- sharpening machine;
- Bulgarian;
- corners (100 x 32 x 5 mm., 2 pcs.);
- mandrels (you can make it yourself or ask to turn it from a familiar turner);
- bolts M8 (2 pcs.).
The flaring tool itself is made very simply: both corners are fastened with a bolted connection, after which holes are drilled in the base of the bed, on the edge of which a chamfer is made. Such a tool will allow you to produce almost perfect flaring of brake pipes, regardless of their length.
The algorithm for processing pipes with such a home-made device practically does not differ from the method of expanding using a purchased factory machine:
- we install the workpiece in the holder and fix it in such a way that the outer edge being processed protrudes beyond the edges by about 5-6 millimeters;
- install a cone of suitable diameter on the tube;
- after the fittings are put on, we make sure that the direction of the thread turned out to be multidirectional (when viewed from the side of the tip of the workpiece, the thread should be directed away from each other);
- we begin to screw the cone into the workpiece, which will lead to a uniform flattening of the edge of the tube. You need to work slowly, making sure that the cone does not go deeper than the set value;
- we take out the part, carefully get rid of the burrs.
As a result, we get a neat, high-quality flared part that can be used for its intended purpose. It might not be a great first try, but once you get the hang of it, you'll be able to finish the edges of your brake lines just as well as you would with factory tools.
Pros and cons of expanding tubes with your own hands
There is no doubt that, working for yourself, you will treat all stages of the technological process with the greatest possible responsibility and diligence. Of course, in this case, you will not need to go somewhere and pay someone to do such work.
But there are obvious disadvantages - we have already given the approximate timing of the scheduled replacement of brake pipes. And since they break down relatively rarely, it is quite possible that you will have to use the tools you purchased or made on your own once, at most twice. However, if you are the owner of a heavily worn car, it is likely that the tubes will have to be replaced much more often.
Do-it-yourself flaring of brake pipes is a simple task, but subject to the availability of a specialized tool. And what is more profitable - to buy it, to make it yourself, or still take the tubes to specialists, you must decide for yourself. The main thing is that the braking system of your car is always in perfect condition.
People who travel a lot quickly become interested in the question of how to flare a brake pipe with their own hands. First of all, this is due to the understandable desire of manufacturing plants to save money: in the old days, for the manufacture of these parts, as a rule, copper was used, which is much more resistant to aggressive living conditions and temperature extremes. Now they are made of steel, which corrode much faster. The second culprit of unscheduled brake pipe wear should be considered utilities. Chemical reagents and salt, generously sprinkled to fight, for example, with ice, significantly accelerate the rusting of the metal and reduce the life expectancy of many parts released by the factory. And the third factor that makes it premature to engage in brakes is the infamous Russian roads. Potholes and potholes create off-design physical stress, due to which the tubes are deformed, or even burst; in addition, they act as a repository of chemical reagents even when the snow has already melted (in spring). All together leads to the fact that the mentioned parts fail not after 70-100 thousand km, as the manufacturer expected, but after 30-50, and even then - in the best cases. How to flare a brake pipe with your own hands: the process is quite simple, but it will require the purchase, self-production, renting or borrowing from a neighbor in the garage a special device for carrying out these works. But if you decide to buy a flaring machine, don't be tempted by the cheapest options available on the market. Yes, you can take a device for 700-800 rubles, but it will definitely turn out to be completely disposable. It has been experimentally established that a more or less high-quality machine cannot cost less than 1800-2000 rubles or even more. When is it time to change tubes? Signs to look for a flaring kit are:
- During emergency braking, when you press the pedal, a very characteristic creak is heard;
- Under the same outgoing conditions, a rhythmic vibration is felt;
- The braking distance of your car is noticeably lengthened;
- The brake pedal travel becomes freer, it seems to dangle;
- Leakage of brake fluid is possible (this is especially evident when the car is parked for the night for a sufficiently long time);
- Often there is a significant overheating of the brake drums and premature uneven wear of the pads;
- In indirect symptoms - car sideways withdrawal during rectilinear movement.
Flaring and its details Often the main body in the brake tube remains intact, but the structure of its 6-sided head is destroyed. There may be other options: coking of threaded connections as a result of liquid getting on them, clogging them, etc. In such situations, if the length allows, you can simply cut off the defective part. But it is better to replace the tube completely if you are going to carry out such repairs. In addition to the flaring machine, you will need pliers, a pipe cutter, a fitting and a drill. From materials - a little acetone. 
Having figured out how to flare the brake pipe with your own hands, provide yourself with a minimum of such work for the future: put the copper pipe in its intended place. We assure you: you will have to remember about flaring much less often. Even with very intensive use of the machine, you will not need it sooner than after 2-3 years.
