We will need: Clutch slave cylinder Clutch master cylinder Clutch cable Welding springs
Finally, we perform follow-up actions and get a 100% result.
Almost every car owner is faced with the problem of clutch pedal stiffness. The constant load on the left leg when driving slowly during city traffic jams is not for everyone. Why are the pedals on some machines soft, which can be affected by a simple finger press, and on others they are not? This question worries many drivers who are looking for an answer to it.
How to make the clutch pedal softer? Many believe that the main solution to the problem is to replace the clutch master or slave cylinder, as well as remove the spring on the slave cylinder or the large spring above the pedal. These images will not give a significant configuration of the problem. One of the proven methods is the lubrication of the bushing on which the hydraulic fluid bearing works.
In addition to solving the issue of softness, it is also important to take care of the correct regulation of the pedal. How to adjust the clutch pedal? How common image The solution to the problem is to tighten the clutch cable. In this case, the clutch pedal must visually be lower than the brake pedal. While it's best to get a professional clutch adjustment
It is likely that the gas pedal will need to be replaced. And how to carry out with a replacement, if the owner of the car is a VAZ? How to change the gas pedal vaz? In this case, than any other thing, turn to a welder who can weld the gap in a short time. You can usually try to buy and install new part. Having eliminated all the difficulties that may arise with the clutch and gas pedals, there is next question: how to depress the clutch pedal correctly?
This act is very important when driving and caring for the clutch assembly. In order to do everything right, you need to find out and prepare the seat for yourself before starting the ride, and so that the leg distance is longer than the pedal pressed to the stop. The largest is to squeeze the clutch pedal to the stop, without tearing away the heel. And I would like to let go already smoothly and slowly.
How does the gas pedal work? When you press the pedal, it moves to the lower position and pulls the cable. After this, it opens throttle valve, increases the power of the fuel in the cylinders. Then the influence passes to the piston, from it to the connecting rod, which, in turn, makes the crankshaft speed up faster. The harder you press the pedal, the faster the car will undoubtedly go.

So, the clutch... Let's just say it works well on a pit bike, but it essentially has two positions ON and OFF, there is not much smoothness in it. For city driving or cross-country trails, this does not seem to bother at all. But now, if you ride on an enduro theme, I’m sure that you would like the clutch to be smoother and longer-stroke, so that you can accurately dose it and, when necessary, tuck. Not everyone will understand, of course, but a small number of people will still be relevant. When you work with the clutch a lot, whether it's enduro riding or stunt, I would like the clutch to be softer as well, as the fingers really suck from permanent job oak levers.
IN this case Stunt Pete will be considered, but the essence is the same.
The logic is simple, in order for the clutch to be long-stroke, smoother and softer, you need to lengthen the release lever. Our lever is a release rod, which is located inside the cover.
We weld an 8 mm plate between the two sawn parts, due to which the release lever will be extended.
We get such a terrible and ugly thing.
We remove all unnecessary and grind.
This is not in a tricky way we lengthened the clutch release lever.
We insert the lever into place, and, as we can see, an extension of almost 1 cm did not create any problems. The lever does not catch anywhere and even has a margin)
We put the cover in place and install the STANDARD cable. No other changes are required, except for the banal settings.
Naturally, a new cable was installed, which: firstly, was lubricated through the lubrication of the inside of the braid by pouring oil into it, and the lower part was anointed copper grease, to which dirt does not stick, while ensuring good lubrication of the cable.
And finally, the YCF release lever was installed. It has a fairly large overhang, which just compensates for the lengthening of the lever on the motor. That is, with this lever, the release will be complete, without any loss.
What in fact? But in fact, the owner was satisfied with the work, and the clutch, EVEN on a 140 engine on the secondary, is squeezed out with one finger.
When you drive Russian cars for a long time, you get used to their peculiar comfort and it seems that everything is not so bad. But it's worth switching to good foreign car Then you immediately realize that you were wrong.
The finalization of the VAZ clutch pedal is that you need to drill a hole with a diameter of about 6 mm in a plastic sleeve, which includes the fork shaft. Rather, before that, you should first select a suitable cork, and then make a hole according to its size.
 |
|
| Before drilling a hole in the sleeve, select a suitable plug to plug it later. | |
 |
 |
| Flowing down the shaft, oil lubricates top support, and then hits the bottom one. | |
In the resulting hole for several days you need to fill in 5-10 drops engine oil and close it with a cork. Thus, the oil will seep into the gap between the sleeve and the fork shaft, flow down the shaft and lubricate the lower support. The clutch pedal will be soft without gearbox repair. Lubrication will also eliminate clutch pedal squeaks. Such a refinement is suitable not only for the VAZ 2110, but also for the VAZ 2109, because. the gearboxes of these cars are of the same type.
By the way, if the car is old, then the clutch drive already has wear, distortions and, as a result, difficult movement of the clutch. Fulfill
The hydraulic drive of the clutch release system has been used in the automotive industry since time immemorial, for hundreds of years. The design was practically unchanged for half a century. And yet, sooner or later, the drive fails, too late - if you are a fan quiet ride, early - if you like to light it up. The clutch pedal is the first indicator of the operation of the basket and the master cylinder. The clutch pedal has become soft, which means it's time to restore the hydraulics, often it is she who has exhausted her resource.
soft pedal clutch implies a whole bunch of related troubles:
- speeds switch poorly, hum and ringing in the box, synchronizers work at the limit of their capabilities;
- slow return to normal
- an under-squeezed clutch loses its performance and resource many times faster.
For your information! Job soft clutch you might even like it, there are often those who are looking for ways to make the clutch pedal softer. One of these options is implemented simply by adjusting the nuts on the rod of the working cylinder. But it is unlikely that the mechanism will like it.
The most annoying of options when the clutch pedal is soft and the gears are not engaged, the diaphragm spring petals are broken or destroyed, as a result of which the clutch is constantly not engaged. If, when trying to pick up speed sharply, the smell of burnt linings appears, not everything is in order with the spring, it may be necessary to replace the entire basket structure.
Often, drivers consider the cause of a malfunction and the fact that the clutch pedal has become soft, simply incorrect adjustment, deformation or breakage of the fork, non-compliance with the basic operating parameters of the device. To increase efficiency, it is worth increasing the stroke of the rod, and the soft pedal will disappear.
Most often, drivers complain that the pedal has become soft after replacing the clutch. If the adjustment does not help, you should pump the hydraulic circuit, tubes and cylinders as efficiently as possible. During any repair, air enters the piping system. If, after assembly, the fittings of the pipelines were not tightened thoroughly enough, the system will be sure to be airy, as a result, the pedal is soft, without a hint of work.
Sometimes a simple and effective procedure is carried out for additional verification. Perform a couple of strokes with a soft drive pedal and fix it in the depressed state. With a key of 8, the fitting for supplying fluid to the working cylinder is unscrewed until air bubbles appear or the “brake” leaks. After completing the procedure a couple of times, we check the fluid level in the tank. In a normally operating mechanism, the liquid will go into the system, but at the same time there should be no leakage of “brakes” in the area of \u200b\u200bthe stem and at the junctions of pipelines.
Both cylinders - the main and working ones - should be subjected to a separate check. The softness of the effort indicates the presence in the transmission chain of the pedal - fork - release bearing - a non-rigid element. As statistics show, the working cylinder is prone to jamming, and the main one is prone to loss of tightness and loss of pumping functions.
If these manipulations do not work, and the pedal remains soft, remove master cylinder drive and revise it. Usually, the loss of the ability to pump brake fluid into the circuit is associated with destruction, crease or catastrophic abrasion of the cuffs.
Important! If the soft pedal effect occurs when low temperatures air, and when the engine warms up, the clutch operation is restored, we can conclude that the cause of its occurrence is the loss of elasticity of the cuffs of the main cylinder.
Alternatively, the defect associated with the appearance of the effect of a soft pedal was often eliminated by selecting brake fluid with more high viscosity.
For cable clutch drive systems, the appearance of a soft pedal means deformation and destruction of the drive foot or release bearing. To check the operation of each element, you will have to conduct great job to disassemble the crankcase and gain access to the release bearing. If the defect appears periodically, the cause may be the destruction of one of the damping springs of the driven disk. A fragment of the spring got into the space between the discs, thereby preventing the spring from fully engaging the clutch.

If you own a vehicle with automatic transmission gears, then this article may seem uninteresting to you, because now we will talk about an indispensable part for vehicles with manual transmission. Of course, we mean the clutch pedal, which just plays the role of the main link between the desire of the driver and the “obedience” of the car. To engage or disengage the clutch, it is necessary to apply a certain force to the pedal, however, if excessive loads are required from the driver, then this clear sign the presence of any problems in the system.
1. Causes of a hard clutch pedal
Why, after all, do we sometimes have to deal with such a phenomenon as a “hard clutch pedal”? In fact, there are several of the most common reasons. Firstly, the pedal lever itself often jams or the cable is rubbed, and secondly, too much wear of the clutch fork bearing can also serve as a source of such problems, due to which it also begins to move tightly. In some cases, tight is due to a blockage in hydraulic system or wear of the release bearing.
Naturally, in order to restore normal operation of the clutch pedal, a number of steps will have to be taken. necessary action, but first, let's try to understand the various signs of the manifestation of certain malfunctions. For example, if the stiffness of the clutch pedal is the result of wear on the fork bearing, then when you press the pedal, you will hear a certain characteristic rumbling, indicating that the release bearing has already worked out its allotted time, and it is time to replace it with a new part.
The mechanisms produced today are designed to overcome sufficiently large distances (more than 1300 km), however, the driver will not interfere with regular diagnostics and the timely elimination of emerging problems (including the replacement of broken parts). In those cases when the system is treated negligently and inattentively, the clutch pedal will serve you on the strength of 50,000 kilometers, and in large trucks problems can be caused by poor lapping of new elements.
should not be excluded from possible causes"hard clutch" and the problem of incomplete inclusion of the mechanism. In such situations, when changing gear, the driver vehicle hear a characteristic rattle. This is due to the inability of the driven disk to normally break away from the pressure disk. To fix this problem, it is best to immediately contact the professionals.
Incomplete shutdown of the device also has its reasons. These include:
- incorrect cable adjustment;
Jamming of the driven disk;
Incorrect assembly of the system node;
Disk warping;
Strong wear of the switching mechanism.
The problem of a "hard" clutch pedal occurs in different machines, and hydraulically powered vehicles are far from an exception. If you are the owner of just such a car, then you should know that a tight clutch pedal can be due to several reasons: a bent fork, coked splines input shaft, along which the driven disk slides, contamination of the sleeve along which it moves, as well as damage to the inside of the flexible hose of the hydraulic drive system. These are the most typical explanations for the problem. tight pedal, but they are far from the only ones.
For example, a piece of rubber can peel off on old hoses, which in the end will play the role of a kind of valve, so if you look for the reason without dismantling the gearbox, you can replace the flexible hose and bleed the clutch yourself, and if this does not help, then contact the service specialists.
2. What should I do if the clutch pedal is hard?
If the clutch pedal on your vehicle suddenly becomes tight, and the gears shift with a certain effort (and it happens that the speed does not turn on at all), first of all, you need to establish the exact cause of this phenomenon. It is likely that you will need complete replacement and adjusting the clutch cable. This process has its own characteristics, and before installing a new element, it is necessary to lubricate it well special fluid. For this, WD-40 is often used.
In addition, often the clutch pedal is simply impossible to squeeze out. Often this is preceded by its excessively light pressing or complete "failure". Such breakdowns are often associated with improper adjustment of the cable or with its breakage. In such cases, it would be useful to check the condition of the release bearing, which can be damaged, which is why it is difficult to press the pedal. You should also check for damage and the diaphragm spring located on the pressure plate.
If you are accustomed to repairing your vehicle yourself and are familiar with the features of its design, then such a check can be performed in independent order, but in most cases, car owners prefer to seek help from service station specialists.
3. How to fix it?
The easiest way to "soften" the clutch pedal is to lubricate the release bearing guide and clutch fork support. Certainly, this way will help to fix the problem only if more than serious malfunctions and defective parts. To perform this task, it is not at all necessary to dismantle the gearbox. Just remove the cable from the fork, then the protective elastic band, and then fix the fork so that it does not slip out of the mustache thrust bearing. After completing these tasks, take a flashlight and see if there is enough lubrication in the mechanism.
If it is missing, then gently clean the dirt with a wire and lubricate the part. Move the fork to different sides, so the lubricant is better distributed over the entire surface. Also, do not forget about the support located behind the fork, it must also be well lubricated. Of course, due to limited engine compartment performing all of the above actions is quite inconvenient, but if desired, nothing is impossible. Therefore, be patient and boldly proceed with the task.
