Replacing the Clutch Slave Cylinder VAZ 2105 ~

Nobody wants to experience discomfort while driving, especially if it is associated with problems in driving. Owners of domestic “classics” have to devote more time and effort to the condition of their car, because they are used to doing everything with their own hands. We can say with complete confidence that if a car owner has already mastered the process of wheel alignment adjustment , then he can also repair the hydraulic drive of the transmission clutch, just study the technology.

General information

In order for the replacement of the VAZ 2107 clutch slave cylinder to be justified, it is good to know its purpose and the first signs of a malfunction. The torque transmission system on classic VAZ models is driven by a hydraulic drive, the main task of which is to transmit force when pressing the clutch control pedal.

In turn, the hydraulic drive consists of two cylinders: the main and the working. When the pedal is applied, pressure is created in the main center, as a result of which the brake fluid is pumped through the valve into the working cylinder (WC). The latter activates the rod, which squeezes the fork, thereby selecting gears.

Traditionally, the control center is located on the gearbox housing and secured with two bolts, so it can only be reached from under the bottom of the car. The operation of both cylinders depends on the presence of brake fluid, so you need to monitor its level, especially since this is not difficult to do - the container is located in the engine compartment.

Replacing the clutch master cylinder VAZ 2101-VAZ 2107: 2 comments

) What’s incomprehensible here)? 1) — pump out the fluid from the clutch reservoir so that after disconnecting the hose, it does not flow down. 2) We move the washer fluid reservoir to the side, as it will interfere with operation... (we move it closer to the radiator grille) 3) We unscrew the metal tube from the clutch master cylinder. This is where WD40 may come in handy and a good wrench is advisable. Also be prepared that these metal hoses may break if they have not been unscrewed for a very long time. 4) unscrew the lower clamp on the rubber hose supplying fluid to the clutch master cylinder, pull out the hose itself and drain the remaining fluid in it. (a cut bottle may come in handy here) 5) Unscrew the clutch master cylinder itself. This can be done with a regular key, but if you have an adapter tube, then this is just super) 6) An important point - when installing a new clutch cylinder, you should at least slightly press the clutch pedal. This is necessary so that the plug comes out at least a little and you put a new main one on it. That's all, good luck with the repair)

Purpose of the device

Cars are equipped with clutch master and slave cylinders, without which the operation of the mechanism is impossible. The VAZ 2107 clutch master cylinder is designed to push out brake fluid. Below is a diagram from which you can visually find out the operating features of the unit.

When you press the clutch pedal, the piston moves in the device in question, thereby pushing out the brake fluid. This fluid flows through a tube into the working cylinder

, where the reverse process is observed (the liquid pushes the piston out). Brake fluid drives a piston, which is connected by a fork to the clutch disc. As a result, the clutch disc and flywheel are separated, allowing you to change gear. The GCS is also called the main one, since it is with its help that force is supplied from the pedal when it is pressed.

The need to replace the device: when required

Like all parts of any car, the GVC tends to wear out, resulting in the need for repair or replacement. The simplest breakdown of a product is wear of the boot, which can be determined by the characteristic signs of a fluid leak.

To identify a cylinder malfunction, an initial visual inspection is required. It is possible to repair a failed main circulation system on a VAZ 2107; for this you can look for repair kits, but this is not always rational due to the quality of modern spare parts, so it is easier and faster to replace it entirely. The malfunction can also be determined by the characteristic loss of pressure in the system, which is determined by pressing the pedal. Let’s take a closer look at how to change a faulty VAZ 2107 mechanism.

Each car in its design is equipped with such a device as a clutch master cylinder. The car in question, like most modern cars, is also equipped with a master and slave cylinder in the design of the clutch mechanism. In this material we will pay attention to the clutch master cylinder on the VAZ 2107, its location, diagnostics and replacement features on the seven.

When is it necessary to replace a faulty clutch slave cylinder on a VAZ 2107: signs and causes

In most cases, clutch control problems are associated with loss of tightness, when the pedal loses its elasticity when pressed. However, this fact is not so bad, but the inability to engage the gear is already serious.

If we put together the signs indicating the need to replace the clutch slave cylinder on a VAZ 2107, we get the list:

A drop in the level of brake fluid in the reservoir, which indicates a loss of tightness of the hose or brake fluid. The breakdown is also determined by the spots under the car.
Periodic “failures” of the pedal or its soft movement indicate air entering the system. Failure may be the result of a worn cuff or cracks in the working cylinder body.
A gradual loss of pedal stiffness and difficult gear shifting indicate a broken RC spring. In this case, the fluid level remains unchanged, and adjusting the pedal does not produce any results.

Liquid leakage from the master cylinder is signaled by similar signs, so during inspection you need to pay attention to its condition.

Adjusting the clutch of VAZ 2107, 2105, 2104 cars

Correct and precise operation of the clutch on VAZ 2107, 2105, 2104 vehicles is ensured by certain adjustments to its drive. There are two of them: adjusting the gap between the pusher and the piston of the clutch master cylinder and adjusting the free play of the clutch pedal.

Adjusting the clutch drive of a VAZ 2107, 2105, 2104

Adjusting the gap between the pusher and the piston

The gap between the pusher and the clutch master cylinder piston is 0.1 - 0.5 mm. It is regulated by rotating the clutch pedal free travel limiter. In this case, a certain free play of 0.4 - 2.0 mm is formed at the clutch pedal, which the driver selects when starting to press the pedal.

The gap between the pusher and the piston, free travel of the clutch pedal for VAZ 2104, 2105, 2107

It is measured with a ruler or tape measure, which is installed from the floor to the middle of the lower part of the pedal platform. We move the platform with our hand relative to the ruler scale by pressing the pedal. If there is a gap, at first the pedal moves very easily, and then with difficulty. If there is no gap, turn the pedal travel limiter out a little. We ensure that the free movement along the ruler fits within the required two millimeters.

This gap is necessary for the clutch to disengage completely. If it is missing, then the piston will not be able to fully return to the rear position when the pedal is released and in the working cavity of the master cylinder, and excess pressure will remain in the entire drive. As a result, the clutch will not disengage completely, since the release bearing will press on the leafs of the pressure spring, and the discs will slip (not be fully pressed against the flywheel). Increasing this gap will lead to the fact that the clutch will not disengage completely and will “drive” (the discs do not fully move away from the flywheel).

How to change the Lada slave cylinder yourself?

To work you will need the following set of tools:

Pliers.
Open-end wrench “17”.
Head "13".

It is more comfortable to carry out the repair process on an inspection pit or overpass. If this is not possible, the front part of the machine must be jacked up and placed on supports, having previously secured the rear wheels with shoes. Further work is carried out on the following transitions:

Loosen the nut of the hose tip in the RC plug using a 17-mm open-end wrench.
Using pliers, disconnect the tension spring.
Unbend and remove the cotter pin at the end of the pusher using pliers.
Using a 13mm socket, unscrew the two bolts securing the cylinder to the gearbox housing.
Disconnect the bracket that was secured with bolts.

Having removed the pusher from the fork, take the RC in your hand and, using a 17mm wrench, completely unscrew the tip nut and remove the hose.
Replace the clutch slave cylinder on a VAZ 2107, and immediately tighten the hose tip to avoid loss of brake fluid.
Attach the new part in reverse order.

A certain part of car enthusiasts prefer to drain the old brake fluid before surgery, believing that this will allow them to get rid of dirt in the system. Be that as it may, you will have to bleed and adjust the clutch in any case.

How to bleed the clutch control system?

For the quality of transmission operation, the absence of air in the system is important, which is why bleeding is done. The procedure is similar to bleeding the brakes. An assistant is needed to complete the work:

Fill the reservoir on the master cylinder with brake fluid.
Place a rubber hose of the appropriate diameter onto the fitting. Place the other end of the hose in a container with some liquid.

Ask an assistant to press the pedal 5-6 times and hold it in the pressed position.
Using a “10” wrench, unscrew the fitting half a turn and release air bubbles, then tighten the fitting and repeat the procedure until the air in the liquid completely disappears.

During work, it is important to monitor the fluid level in the tank and replenish it in a timely manner.

How to repair a VAZ hydraulic drive

Main

remember that in all cases of such repairs, after it has been carried out, it will most likely be necessary to bleed the hydraulic system. It must be done according to the instructions for this car model. So, to replace the clutch master cylinder in a VAZ 2107 we will need:

wrenches;
syringe, container;
screwdriver, pliers.

Use a syringe to pump out the fluid from the master cylinder reservoir.
Having loosened the clamp, pull the tube off the tank and drain the liquid from it into a substitute container.
We unscrew the fastenings of the pipe connecting the first and second hydraulic drive units.
By pressing the pedal, we remove the broken link of the system.
We install the new spare part in the reverse order.
Add the missing liquid to the reservoir.

Changing the master cylinder of a VAZ 2106 is carried out in the same way. But the work of replacing the working cylinder of a VAZ 2107 will have to be carried out using a slightly different method. True, we’ll take the same tools.

Loosen the connection between the broken hydraulic cylinder and the hose.
Using pliers, remove the spring from the assembly.
Unsplint the pusher inserted inside the fork.
We unscrew the two bolts securing our broken element to the system housing near the gearbox itself.
We disconnect the accompanying bracket for the spring, and then remove the broken hydraulic device.
We completely unscrew the hose from the assembly and drain the brake fluid from it.
We replace the clutch cylinder with a new one in the reverse order.

Replacement

the working cylinder of the VAZ 2106 is carried out similarly. Moreover, during the work of reinstalling both the first and second links of the hydraulic drive on any modification of the “classic”, you must follow the instructions given.

Replacing the Clutch Slave Cylinder VAZ 2105

Clutch, replacing the driven clutch on a VAZ 2101-VAZ 2107

is working , not all people know that it is all the same, but you will still have to replace it from time to time, but how to replace it if not everyone knows what it really is? Short. In the car we are now looking at the classic, there are two clutch cylinders, one of which is the main one and the other is the worker. They actually perform the same function, when you press the clutch pedal, the piston (indicated by the green arrow) inside the clutch master cylinder moves and thus pushes the brake fluid further.

At this time, the brake fluid continues its own path and thus rests on the same piston (indicated by the blue arrow) that is already in the clutch suspension cylinder, and after the brake fluid has settled, it will begin to push on the piston. it moves forward, and when you press the fork, the clutch in the car is disengaged.

In general, we understand that there should be constant brake fluid , but why would either of you ask? The fact is that brake fluid is not compressed, and therefore is used as a brake system. So, in the clutch drive, let's get back to the topic.

To replace your clutch master cylinder with a new one, you'll need to stock up: you'll still need a basic set of wrenches, as well as some pliers and about 1.2L of new brake fluid!

Where is the clutch slave cylinder located?

It is located next to the box, and to be more precise, it is attached with two bolts to the box clutch housing, so it can only be clearly seen if you are under the car or if you look into the engine compartment. For a more detailed location, see the photo below, it is indicated by an arrow:

When should I replace my clutch master cylinder?

As we already understood, there is brake fluid inside the working cylinder, due to which the clutch in the car disengages, but it happens that over time this cylinder becomes unusable, and cracks begin to appear in its body, and gradually the fluid that comes out of it , begins. Based on this, it is not at all difficult to understand if you look at it visually, and you can also realize it without even looking at it, how are you asking about it?

The whole point is that if the cylinder fails and brake fluid begins to come out of it, the first thing that happens to the clutch pedal is that it is not difficult to press, in other words, the system will not be tight, so to speak, and if the system does not tight, the clutch won't work, in other words, you press the pedal, it's not at all difficult to press the clutch However, it doesn't get it, but this is probably one of the most common problems that occurs when a suspension cylinder fails.

VAZ 2107: clutch repair in garage conditions

And again we are repairing the VAZ 2107

Clutch problems? Does it not engage completely, is the clutch pedal “soft” or does it fail altogether? All this will tell us that the time has come to repair the clutch - the master and slave cylinders! How this is done will be discussed in this article. Here you will find: instructions for repairing the clutch on a VAZ 2107 car, a useful video, tips and features of this type of work. Here you will find information on how to change cylinders, repair and bleed them.

Preparing for clutch repair

What you need to prepare in order to repair the clutch yourself:

A set of keys
Screwdriver (preferably thin)
Special pliers-pullers
WD-40 or similar rust remover
Knife
Brake fluid
Bleeding hose
Bleeding container
Syringe

That's probably all that is needed.

Expanding pliers (circlip pliers)

Clutch replacement

Often, car owners prefer to simply replace clutch parts, since the cost is low and time can be saved significantly. Therefore, you can first consider the process of replacing clutch parts.

Replacing the clutch master cylinder

First you need to drain the fluid from the clutch reservoir. This can be done using a syringe - select the liquid and pour it into another container.
You can also remove the hose from the master cylinder fitting and insert it into the same container. Slightly straighten the clamp on the fitting to make it easier to remove the hose. Do whatever is more convenient for you.
After this, you need to unscrew the pipe fitting that fits the clutch slave cylinder.
Then spray the two studs that secure the clutch master cylinder to the car body with WD-40 or an equivalent to prevent breaking them when unscrewing the nuts.
Take a 13mm wrench or a socket with extensions (whichever is more convenient) and unscrew the two fastening nuts one by one.

Removing the nuts securing the main brake cylinder VAZ 2107

Remove the clutch master cylinder.

Ready! Withdrawal completed. Now let's install the new cylinder:

Advice! Before installing a new master cylinder, pay attention to the condition of the clutch reservoir flexible hose. It often happens that it cracks at the end. There are two options - either replace the hose or cut it (if the length allows).

First you need to get the drive rod from the clutch pedal into the hole in the new master cylinder. For convenience, ask a friend to press the clutch pedal a little.
Then install the clutch master cylinder onto the mounting studs.
Tighten the fastening nuts with a 13 mm wrench or a socket with extensions.
Using a 10mm wrench, connect the pipeline from the clutch slave cylinder.
Install the clutch reservoir flexible hose.
Fill the reservoir with brake fluid to the filler neck.

The master cylinder has been replaced.

Replacing the clutch slave cylinder

Clutch slave cylinder for VAZ 2107

Now we will change the clutch slave cylinder on a VAZ 2107:

Advice! When unscrewing and tightening the slave cylinder mounting bolts, be careful not to strip the threads in the gearbox housing.

Remove the spring from the slave cylinder.
Next, you need to unscrew the tube that connects the main and working cylinders using a 10mm wrench. Brake fluid will flow from it - put the cap on the end of the tube, which is located on the bleeder fitting of the working cylinder.
Unscrew the two bolts securing the working cylinder using a 13mm wrench and remove them together with the plate.
Remove the slave cylinder.

The procedure for replacing the VAZ 2107 clutch:

1 remove the gearbox

2 in the case when it is necessary to install the previous pressure plate, it is necessary to note the relative position of the flywheel and the disc casing. This is done to maintain balance by installing the disk in the same position as it was previously. The mark is made with a dash or paint.

3 Next, install the mandrel in the pressure plate hole

4, use a powerful screwdriver to stop the flywheel from turning, resting it against the teeth, then unscrew the 6 bolts securing the clutch pressure plate housing to the flywheel. We remove the bolts gradually, each bolt one turn of the flap, and so on around the perimeter of the flywheel.

5 Now we dismantle the clutch housing assembly with the pressure plate

6 then we remove the driven disk along with the frame

VAZ 2106; VAZ 2105; VAZ 2107; VAZ 2104; VAZ 2101

7 After removing the clutch driven disc, we carefully inspect it. If cracks are detected, the disc is rejected. Also, wear of friction linings 1 is not allowed; a recess of more than 0.2 mm in the rivets of head 2; oiliness of friction linings; loose rivets. It is also necessary to check the quality of fixation of damper springs 3 in the sockets of the driven disk hub. If the springs are broken, the disc must be replaced.

8 Next, we check the driven disk for radial runout. If the disc moves in diameter by more than 0.5 mm, then the disc must also be replaced

9 inspect the working surfaces of the flywheel, as well as the pressure plate. The main attention should be paid to signs of overheating (a dark smooth spot), deep marks, cavities, splinters, scuffs, scratches, potholes, and other signs of wear. Replace components if such defects are present.

10 we also visually assess the condition of the disc spring 1 of the pressure plate. If there are cracks, the part is rejected and must be replaced. Inspect the contact points of the spring petals with the clutch release bearing for wear. If wear is higher than normal, then the entire pressure disk assembly must be replaced. Also, if there are rivets on 2 parts of the casing and the pressure disk, the pressure disk assembly must be replaced.

Clutch repair

Now let's consider another option - using a repair kit for the clutch cylinders - main and working.

Master cylinder

So, we have removed the main cylinder and now we begin to disassemble it.

VAZ 2107 clutch master cylinder repair

We start by removing the fitting. Use a screwdriver to remove the retaining ring.
After which you can easily remove the fitting with the gasket.
Now remove the rubber boot (protective cap) by simply prying it with a screwdriver or other convenient object.
Now, using a 22 key on the other side, you need to unscrew the plug of the VAZ 2107 clutch master cylinder.
You also need to remove the retaining ring from the boot side. This can be done using two screwdrivers, or special pliers. It is more convenient to use expansion pliers.
Now you can easily remove all the insides of the cylinder.

Now about damaged parts and their replacement:

Clutch master cylinder of VAZ 2107 disassembled

All rubber seals should be replaced. 2 rubber rings - on the piston and pusher rod, one on the fitting, and we also replace the protective cap if necessary.
If necessary, replace the spring. If it is deformed or damaged.
Also pay attention to the internal mirror of the cylinder. It should not have burrs or chips.
If the piston is damaged or the pusher is bent, then it is better to replace the cylinder with a new one.

When assembling, all parts should be washed very thoroughly.

Note! Never wash parts in gasoline or oil and do not allow these liquids to get inside the cylinder. Lubrication is carried out only with brake fluid!

Put all retaining rings back.
Tighten the clutch master cylinder plug tightly!

Then install the cylinder back on the car. This is how the clutch master cylinder is repaired on a VAZ 2107 car.

Working cylinder
