It is extremely important at first to learn how to feel the car, and not just perform some jagged actions with your feet. Having understood this, you will soon learn how to start moving smoothly. There is one exercise that you can do to check how smoothly you lower the clutch. To do this, you need to fill a plastic cup with water. Directly by the level of water that will remain after you complete the exercises, and it will be possible to determine the degree of smoothness of lowering the clutch by you.
Some people sometimes have an erroneous opinion in the matter of depressing the clutch that the heel should rest on the floor. In fact, this is not so. You need to choose a position in which your heel will be on weight. Slightly bend the leg at the knee, work with the leg, not the foot. That is, press the clutch pedal fully in weight, release to a certain point, and only then put your heel on the floor. The subsequent one is carried out with the feet.
Own travel of the clutch - about 2-3 cm relative to the total travel of the clutch pedal. That's why experienced drivers try not to depress the pedal to the end. As a rule, in driving schools, they first teach you to get under way and drive without gas. Then - learn to carry out the same operations, but with gas. Thanks to this, in the end, you can learn to release the clutch smoothly, gasping.
The most important thing in the process of starting the movement is to feel the moment of “seizing” of the clutch. You can visually track this moment on the tachometer. After that, gently press the gas pedal, the car will start moving, then gradually release the clutch. Practice more, over time you will learn everything correctly. Experience plays a huge role here. Do not be nervous, otherwise your actions will be abrupt, which will not give a smooth ride to the car.
A harsh clutch pedal is the most common problem for newbies learning the basics of driving. The inability to move off smoothly and accurately is inherent not only to girls, but also to young people who first sat behind the wheel of a car.

The reasons for a sharp reset of the clutch pedal, as a rule, are "misunderstanding" of the car and excessive excitement. If everything is clear with the last reason, then the first must be explained. So that the car does not seem uncomfortable to drive and cumbersome, it needs to be “felt”.
There are practical exercises to master the smooth depressing and releasing the pedal. To acquire the first skills, select a site, free and people. A plot of 30x30 m is enough. The driver must drive the car to this site.
The first exercise is aimed at keeping the engine speed. Place your right foot over the accelerator. Depress the clutch pedal and engage first gear. Release the handbrake lever while continuing to hold the clutch in. So you prepared the car for the exercise.
Start releasing the clutch pedal very slowly, while watching the behavior of the car: the engine will be loaded, its speed will begin to fall. Your left foot should memorize this clutch engagement position.
As soon as you feel that the engine has reacted with a decrease in speed, stop releasing the clutch in this exercise. Pause a little and depress the pedal, then disengage the gear. If the engine, having slowed down, does not stall, the goal of the exercise has been achieved. If it stalls, do the exercise again.
The next exercise is aimed at the smoothness of squeezing the pedal. To carry it out, you need to take a plastic cup filled to the top with water. The essence of this exercise is to judge how smoothly you start off by the level of water remaining in the glass at the end of the exercise. If the glass is still full, you did everything right. If not, you need to practice the previous exercise.

Clutch replacement is enough difficult process, for the successful implementation of which you must have the skills of an auto mechanic. But it is wise to choose according to the strength of any motorist.
Instruction
Pay attention to the mass of the clutch. This parameter is one of the most important. Almost all manufacturers try to observe and control this value. Therefore, when buying, check the mass by touch. Also decide on the amount of torque, because failure to comply with this value can lead to damage to the transmission, as well as make very hard pedal clutch.
Pay attention to the clutch mass, given parameter is one of the most important. Almost all manufacturers try to observe and control this value. Therefore, when buying, check the mass by touch. Also decide on the amount of torque, because failure to comply with this value can damage the transmission, as well as make the clutch pedal very tight.
Carefully inspect the surface of the driven disc lining, which should be uniform and free of signs of damage and roughness. Also unacceptable is the presence of oil stains. Examine the quality of the riveting, as well as the springs in the damper, which should not show signs of play.
Not the last selection criterion is the cost of the product. Remember that expensive equipment is not always of high quality. Pay attention to manufacturers who have been in this market for a long time. These include Valeo, Luk, Sachs and Kraft. However, often famous brands are under attack by numerous fakes. Therefore, before going to the store, be sure to analyze the information that can be found on the Internet or learn from familiar motorists.

When driving a car with a manual transmission, the most problems arise with clutch. Many people find it difficult to get used to the shifting sequence and the manipulations that go with it. But if you learn to work right clutch, you are provided with competent driving.
Instruction
The main role is that when it is pressed, the engine stops interacting with the gearbox. At the moment of braking, this manipulation, roughly speaking, disconnects the engine from the wheels. Wrong work clutch pedal may cause it to overheat.
To start moving, you need to squeeze and turn on the first gear. Then press the gas pedal and at the same time depress the clutch pedal. All these manipulations must occur simultaneously. If you release the gas slowly, then your foot is in no hurry to go anywhere. If you want to start fast, then all pedals are pressed quickly. But in all cases, the clutch pedal does not rush. As soon as it goes, hold your foot a little at the very end of the clutch and release it completely only after driving a few meters.
For the next gear change, you need to release the gas pedal, press the clutch and select the desired gear. After that, simply release the clutch and hit the gas. If you press the gas without releasing the clutch pedal, the car may jerk uncomfortably. This big mistake.
At the moment of braking, it is necessary to grip at the same time. After a complete stop of the pedal, do not throw, but turn on neutral. If you release the clutch early, the car will stall. For quick braking while riding, do not put your left foot on the floor. It should rest on the heel and lie on the pedal.
When driving slowly in traffic jams, many hold the clutch constantly so as not to turn the speed back and forth. But in this mode, overheating occurs, and you may feel a sharp burning smell in the cabin. In a single case, this is not scary. But with a constant neglect, the service life of the cable is noticeably reduced. And on some foreign cars it is expensive. The first signs can be considered the inclusion of a gear not the first time and a characteristic growl when the clutch is released while driving.

If during the movement of the car there is a smell of burning, if acceleration has noticeably worsened, if the speed begins to fall when overcoming the rise - all these are symptoms of clutch slipping. To determine the problem more precisely, tighten hand brake with the engine running and shift into gear. With a good clutch, the engine will stall, with a slipping one, it will continue to work.
Often common causes of this unpleasant phenomenon are a violation of the free play of the clutch pedal, oiling friction linings in the mechanism, wear of the pressure springs or a malfunction in hydraulic drive off. To eliminate slippage, first measure free play clutch pedals. It is he who ensures the operation of the mechanism during slipping. The measured value is compared with the value set according to the instructions for the car. If there are discrepancies, they are adjusted in accordance with the recommendations set out in the same instructions. If the free play of the pedal is correct, check the oiliness of the friction linings. It is more likely that this may be due to advanced level oil in the gearbox or clogged flywheel drain hole, or due to careless lubrication thrust bearing input shaft gearboxes. Oiled linings are washed with gasoline (kerosene), wiped dry and cleaned with fine sandpaper. A heavily oiled disc is changed along with the friction linings and the causes of oiling are eliminated. When the friction linings of the driven disc are worn clutch can also slip, as the free play of the clutch pedal is reduced. With a slight wear of the linings, the free play is adjusted, with a significant wear, the driven disk is replaced along with the worn linings. Friction linings are also subject to mandatory replacement when cracks are found on their surfaces, when they are unevenly worn and burnt out. Loss of elasticity of pressure springs is a natural process that manifests itself as a result of their long work. However, they do not create sufficient pressure on the driven disk, and clutch starts to wobble. To check the condition of these springs, special devices and devices, so it is recommended to do this at a service center. Another reason for clutch slipping may be swelling of rubber parts or clogging of the compensation hole in the hydraulic drive to turn it off. These parts can be: rubber sealing rings and a rubber annular floating valve of the master cylinder piston, rubber seals of the working cylinder. The reasons for their swelling are the use of low-quality or inappropriate brake fluid, as well as the ingress of gasoline, kerosene or mineral oil.
To predict the behavior of a car on the road, the driver must take into account the coefficient of adhesion of tires to the road surface, in other words, the slipperiness of the road. This factor depends on weather conditions, and from the type pavement.
Instruction
Remember the factors that reduce the coefficient of grip of tires with the road. This is a wet coating (puddles), oil and oil stains, sand and snowdrifts, ice They also include weather factors that increase the slipperiness of any road surface. One of the most dangerous is driving through large puddles, which can cause hydroplaning, which reduces the grip of the wheels to zero.
Always keep in mind that ice is a selective phenomenon. In other words, it appears more often in certain sections of the route, interspersed with unfrozen places. Be prepared for icing to occur in the shade of trees, buildings, on bridges and overpasses, and on lighter traffic lanes. Always check the road for icing when the air temperature is around zero degrees.
Pay attention to the intersections of the asphalt pavement with dirt roads. During the period of field work, mudslides or after prolonged rains, mud is dragged in these places by wheels. In addition, in hot weather, asphalt releases a binder that significantly reduces traction. Be careful when moving on leaves, especially wet ones.
To check the grip coefficient of the tires with the road while driving at low speed, lightly apply the brake or depress the gas pedal sharply. Moreover, in order to more accurately determine the degree of slipperiness of the road, this must be done several times, each time sharper. The sooner the wheels begin to spin, the lower the friction coefficient.
On slippery road reduce your speed prudently. Avoid problem areas if possible. Try not to drive the machine on its own wheels on the site with good grip, and others by slippery surface. At the slightest sign of braking, the car can spin.
Also remember that the coefficient of adhesion of the wheels with the road decreases in proportion to the increase in speed. So, at a speed of 150 km/h, tire grip will be several times less than at a speed of 30-50 km/h. Hence the conclusion - at the very beginning of braking on high speed tire grip is always less than at the end. This fact is the reason for the non-linear dependence stopping distance from speed.
Monitor the condition and wear of the tread on the wheels of your car. The tread pattern, namely the abrasion of its protrusions, significantly reduces the coefficient of adhesion of tires to the road. Tires with a completely worn out tread will have the lowest value of the coefficient of adhesion - one third less than new ones.

Check the condition of the suspension and air pressure in the tires. These factors also affect the grip of tires on the road.
Some people are familiar with such an unpleasant phenomenon as swelling of the legs above the feet (in the ankles). In most cases, such swelling does not pose a health risk. However, they can also be a symptom of a number of serious illnesses, so you need to see a doctor.
What diseases cause swelling of the legs above the feet
Why do legs swell? Swelling of the legs in the ankle area can appear as a result of heart failure, when the heart is not able to "pump" the volumes necessary for the body. Then the kidneys try to somehow compensate for such a shortage, retaining fluid in the body. Due to the stagnation of fluid in the tissues, it accumulates in the lower part of the legs (under the influence of force). And they swell.
Edema often appears due to kidney disease, as well as disorders in the lymphatic system. In addition, swelling of the lower legs can occur due to chronic diseases of the respiratory system, varicose veins, thrombophlebitis, diseases of the endocrine system, leading to a change in the hormonal background in the body.
They also often have swelling during or, because the composition and concentration of hormones at this time changes.
As you can see, there are many reasons for this phenomenon. Therefore, you should consult a doctor for proper diagnosis and treatment.
Swelling of the legs in the ankle area and the physiological characteristics of a person
Swelling just above the foot can also occur due to excess weight, especially in cases where a person is forced to stand for a long time. Often, similar - a long stay in an uncomfortable position, immobility (for example, during long flights, car trips).
If at the same time a person uses uncomfortable, tight shoes (option - women's stilettos), the risk of edema will increase many times over.
The legs above the feet may swell as a result of taking certain medications, especially those containing, as well as steroids and non-steroidal anti-inflammatory drugs. The same side effect is often caused by drugs to lower blood pressure.
It also happens that the cause of swelling of the ankles is an ordinary sunburn. This is one of the manifestations of the protective reaction of the body to ultraviolet radiation.
Swelling of the legs in the ankle area can be caused by injuries, bites of certain insects, such as mosquitoes. Finally, the cause may be natural age-related changes in the body in older people. In any case, even if you are sure that swelling is not caused by a disease, it is better to consult an experienced doctor. Perhaps, in your case, to remove edema, it will be enough to change the daily routine, nutrition.
A faulty clutch is a much more serious problem than people sometimes think. At the same time, you can diagnose a breakdown yourself by paying attention to extraneous sounds, incorrect "behavior" of the clutch and other problems. Observation and the habit of monitoring the condition of the car will be very useful.
The main signs of a clutch failure
One of the most common "symptoms" of a bad clutch is strange noise that occurs when you press the pedal. You may hear knocking, grinding, or other unusual sounds. Noise can be a sign of a number of breakdowns: failure release bearing or parts of the vibration damper in the driven disk, severe wear and deformation of the splines, loss of elasticity or movement of the return spring. Please note: the pedal may make noise not only at the moment it is pressed, but also when it is released and it begins to rise up. According to the features of the noise, you can determine what kind of breakdown in question.
An even more unpleasant sign of a clutch failure is the occurrence of problems when shifting gears. If you notice this problem, immediately contact the service station, because over time the situation will only worsen, and it will not be safe to drive a car. Diagnosing a breakdown is simple: when shifting gears, a rattle appears, the clutch pedal is not pressed all the way. Later, some transmissions simply stop turning on. There can be many reasons: malfunctions of the clutch cable, failure of the friction linings, diaphragm spring, driven disk.
Faulty clutch: what to look for
To diagnose a clutch problem, it is worth trying to pick up speed on a straight road, gradually shifting gears and carefully observing the behavior of the car. If the car accelerates more slowly than usual, as if it has lost some power, and the clutch often "slips", then it's time to visit the service station. Probably, the surfaces of the flywheel, driven or pressure plate are heavily oiled. It is also possible that the cause of the “slipping” was the incorrect adjustment of the drive, which leads not only to problems in gear shifting, but also to accelerated wear of the elements.
Finally, to understand that the clutch is faulty, sometimes just sniffing is enough. If, after pressing the pedal and shifting gears, you notice a sharp bad smell burnt rubber, the car probably needs to be repaired. In this case, the problem may be the wear of the linings, as well as the failure of the clutch disc. Interestingly, in some cases, the smell may appear only from time to time, and not every time you press the pedal, but this does not mean at all that the car has repaired itself.
Since the clutch is a key part of the car, any signs of a problem in it should immediately attract attention. So, a creak may indicate cable wear, lack of lubrication, or a broken clutch fork.
Proper work with the clutch allows you to operate it without any problems up to a run of 75-80 thousand kilometers. However, for a number of reasons, complications of varying severity can occur much earlier. Talk about serious symptoms that clearly indicate that this car assembly requires urgent repair (the clutch "leads" or it slips), it is worth it only in a car dealership. But you need to pay attention to the case when the clutch creaks.
The main types of clutch squeak
Vehicle operating experience shows that two main types of clutch squeak can be distinguished.
1. A creak that does not affect the operation of the clutch drive or the assembly itself, the so-called "light" creak. Rather, it only annoys the car owner with its sound.
2. "Heavy" or hard creaking. Usually accompanied by a hard pedal stroke or it goes jerkily. Often, motorists talk about the clicks they feel when working with the clutch pedal. Such a squeak can lead to a break in the drive cable or breakage of the clutch fork.
How to try to eliminate squeaks yourself
As people say, the car loves lubrication and affection. Very often, the cause of clutch creaking is precisely the lack of lubrication on rubbing surfaces. Try following the recommendations of experienced motorists.
1. Lubricate the pedal assembly from the passenger compartment with WD type grease.
2. On the clutch fork, slide the rubber washer, remove the cable pin from the slot, wipe off accumulated dirt and process graphite grease the cable itself and the fluoroplastic bushing.
3. Using a syringe, try to lubricate the cable under the corrugation from the side of the fork and clutch pedal.
4. Remove the boot from the clutch fork and work well on the shaft itself and the bushings in which rotation occurs, suitable lubricant. Experts recommend using aerosol molybdenum.
Many believe that the cause of squeaks is a design flaw that allows the clutch fork to vertical movements with a fairly large amplitude. Over time, the fork drops down, and the bearing directly rubs against the input shaft. The problem can be solved by centering the fork by placing washers of the desired thickness in the seat saddle.
Sometimes the pressure finger that connects the pedal to the master cylinder creaks. But lube won't help here. The only thing, do not forget about it when you install a new one.
Can be called more whole line the reasons for the clutch squeak, but in any case, if the simple manipulations described above do not solve the problem, you should contact the specialists.
If the car has a manual transmission, then the driver must know well how to use the clutch pedal correctly. What is this mechanism for and what function does it perform? Even the name "clutch" speaks for itself. With this pedal, the rotation of the wheels is reduced, and the engine operates in the same mode. To be even more precise: there is a spring between the two discs, it closes them, in order to weaken this spring, it is necessary to squeeze the clutch.
In order for the car to start moving, you need to press the clutch and set the first speed. The clutch pedal is on the left, then the brake and the third - gas. It is difficult to press the clutch: it is very tight, a matter of habit, over time you don’t notice it. You need to train to touch flat road so that there are no passers-by or vehicles nearby, and the wheels of the car are straight. For training, insert the key into the ignition, the car must be on the handbrake. We start the car, depress the clutch, remove the handbrake, turn on the third speed and do not press the gas, but just try to feel the car and listen to the speed. It’s great if there is a tachometer (speed sensor), for example, we wanted to catch 2000 rpm, it was displayed on the tachometer, we release the clutch smoothly, the car will not go, but will stall. For a beginner, this is what you need. future driver should feel how and when to release the clutch. Not abruptly, but smoothly and briefly. Repeat several times for skill.
With a strong desire, you can learn how to squeeze the clutch, the main thing is to calmly follow all the instructions and not worry if everything does not work out right away.
The double clutch release technique, in fact, is little known to ordinary people and is only possible on cars with a manual transmission. Its essence lies in the fact that the driver has gained such a number of revolutions of the power unit in the neutral position of the box, so that an optimal switch down one step occurs. This will provide the smoothest movement and reduce the load on the synchronizers. Properly applied double clutch technique increases their service life.
What is a double clutch release?
When the driver downshifts, once squeezing out, then all those present in the car during the movement experience a peculiar feeling that the car is being stretched. With dual clutch, the driver depresses the clutch with his left foot, but on downshift does not switch immediately, but falls into neutral for a fraction of a second. Next, the clutch pedal is slightly released and pressed a little to gain optimal speed engine, and then turn on lowest rung as fast as possible. Simply put, the speed when switching to a lower gear does not fall, which means that the force of tension is not felt. The faster acceleration to downshift occurs, the more you need to squeeze the gas in neutral in order to power unit scored required amount revolutions.
Double Clutch Technique
1. Accelerate the car in first gear to 3,000 rpm.
2. Depress the clutch pedal and release the gas pedal.
3. Engage neutral gear.
4. Take your foot off the clutch pedal.
5. Keep a short pause for synchronization. The engine speed will drop to 2,000, that is, as if you were driving in second gear.
6. Depress the clutch pedal again.
7. Turn on next gear- second in this example.
8. Release the clutch pedal.
9. Increase the engine speed by pressing the gas pedal.
10. In the same way, switching to other gears occurs.
How to master double clutch release?
Mastering the technique of double clutch release is possible only in a practical way, by conducting daily training and stocking up with a certain diligence. Be careful when depressing the clutch and shifting gears, as if handled roughly, you may damage the transmission system car. Remember one thing: everything must be done as confidently and gently as possible. After a sufficient amount of practical exercises gear shifting will become easy and natural. Once the double-clutch technique becomes commonplace, you're unlikely to want to use the conventional shifting technique.
The main problem in mastering this technique, as a rule, becomes the moment when it is necessary to adjust the engine speed up or down in order to synchronize with the gearbox. But just like other driving skills, these techniques are only difficult to learn. Over time, you will do everything on the "machine". Let on mechanical boxes gear modern cars and there are automatic synchronizers, but the use of such equipment will significantly extend the operational life of your manual transmission, because the load on the gears and synchronizers will be absolutely insignificant. The main thing is not to give up! The double clutch technique is excellent, even if it looks a little awkward at first.

Many modern drivers never even heard of such a thing as " double release clutch" when shifting gears in manual gearboxes. However, it will be useful for all drivers to know about this method. You need to start considering this issue with the history of the automotive industry. On old cars in, there were no synchronizers at all.
Synchronizers are devices that equalize the peripheral speed and do not allow the gear to lock up until the speeds of the input and secondary gears are equal. To avoid gearbox breakdowns and extend its service life, the so-called double clutch release(when shifting gears up), and peregazovka when shifting down. In other words, without such tricks without synchronizers it was almost impossible (there would be a rattle).
Let's take a closer look at these switching methods. So, double release is used when shifting gears from lower to upper. For example, let's take the shift from first gear to second.
Double Clutch Technique
- we accelerate in first gear (up to 3000 rpm);
- press the clutch pedal and release the gas pedal;
- turn on "neutral";
- fully release the clutch;
- we make a short pause, during which synchronization occurs (engine speed will drop to about 2000), i.e. if you left in second gear;
- depress the clutch pedal again;
- turn on the gear (in this example, the second one);
- release the clutch pedal;
- increase the engine speed by pressing the gas pedal.
According to the same algorithm, they switch from the second speed to the third, etc.
How to perform a re-gassing
Now about perepazovanie. It is used when shifting from upper to lower gears. For example, consider switching from second gear to first.
- release the gas pedal, and brake the engine in second gear. If necessary, slow down by pressing the brake pedal;
- depress the clutch pedal and fully release the gas pedal;
- turn on "neutral";
- fully release the clutch pedal;
- add a little speed to the engine by pressing the gas pedal, at this moment synchronization occurs (engine speed rises if you were driving in first gear);
- fully depress the clutch pedal;
- turn on the first gear;
- release the clutch pedal;
- moving in first gear.
The main points here are the observance of a pause or regassing, with the neutral gear. The main difficulty lies in right choice the duration of the pause and the correct regassing, but with experience everything turns out to be much easier than it seems at the beginning. With the advent of the skill, everything will happen, as they say "on the machine."
Of course, modern gearboxes equipped with synchronizers (which are just designed to save drivers from all these “double squeezes”) do not require the use of the above gearshift methods, however, if you master them, you can significantly extend the life of the gearbox. In any case, such a skill will not be superfluous, especially when shifting from top gear down. I want to note that regassing down will help extend the life of the synchronizers (the load on them will decrease), and also if the car does not pull uphill, it will help to switch without loss of traction, increasing the torque down.
