How is the clutch master cylinder?

The clutch system performs the function of short-term disconnection of the internal combustion engine from the gearbox. As a result, the transmission of torque from the power unit to the drive shaft of the transmission stops. This system includes many components. One of them is the clutch master cylinder, which we will talk about today.

What is he?

This mechanism is a small cast iron steel with a flange for attaching to the body. On its upper part is a plastic tank with a lid. It is attached to the body with a threaded fitting. Thanks to this mechanism, a special fluid enters the clutch master cylinder. Inside the cast iron part is a piston with a cuff and a sealing ring. There is also a spring that rests on the check valve. It compresses the piston to the extreme right position. When these parts are heated, expansion occurs, respectively, the liquid in the system must go somewhere. For these casesthere is a special compensation hole through which it enters the tank from the cylinder cavity.

How does the VAZ 2107 clutch master cylinder work?

This mechanism is designed so that each time you press the clutch pedal by means of a pusher, it moves forward. And when the piston closes the hole, the pressure in the cylinder increases. Thus, the fluid flows to the slave cylinder and disengages the clutch. When the pedal is released, a similar action occurs, only in reverse order. The fluid flows back - the valves open, the spring is compressed and it moves from the working cylinder to the main one. If the pressure level drops to a point below the compression force of the spring, the first part closes and more pressure is formed in the system. This is necessary to select the gaps of the mechanical part of the drive.

If the pedal is abruptly released, then the liquid will not completely fill the space behind the piston. Then a vacuum occurs in the clutch master cylinder. Because of this, liquid will flow from the plastic tank through the overflow hole directly into the piston. Then it passes through the piston head and fills all the space that has arisen in the part after vacuum. The liquid at the same time removes the edges of the cuff and pushes the spring plastic. And again, if it becomes more than normal, all of its excess passes through a special compensation hole back into the tank.

That's rightthe master cylinder of the VAZ clutch is arranged. In conclusion, I would like to note several ways, thanks to which you can independently identify the breakdown of this mechanism:

• First, you should check the level of the working fluid in the tank. If this indicator drops rapidly, this indicates a malfunction of the piston or cuff.
• Secondly, this part is replaced if you feel the characteristic sound of gears when shifting gears.
• Third, the clutch cylinder is replaced by vibration of the gearshift knob.
