In the article, we will consider the replacement of the master and slave cylinder of the clutch of a car
Removing and installing the clutch master cylinder
We prepare the car for the task and remove the battery
Remove the cap of the reservoir of the main brake cylinder and pump out the brake fluid with a rubber bulb or syringe from the section that feeds the hydraulic clutch release
The reservoir has three sections: two separate sections for the brakes and one section for the hydraulic clutch release
Squeeze the antennae of the clutch release hose clamp, and disconnect the hose from the fitting of the master brake cylinder reservoir
Unscrew the nut securing the hydraulic drive tube from the clutch master cylinder
Unscrew the nut 2 (Fig. 2) securing the clutch release master cylinder, located in the engine compartment
We pry off the spring retainer 4 and remove it from the chamfer of the axis
Remove axle 8 from the fork
Unscrew the nut 3 and completely remove the clutch release master cylinder
We install the parts in the reverse order and remove air from the hydraulic clutch release
Replacing the clutch slave cylinder
We replace the slave cylinder when the clutch is not completely disengaged, most often this occurs when the sealing collars installed in the cylinder are worn
Pry off the edge of the spring clip with a screwdriver and remove it
Disconnect the tip of the tube from the working cylinder
We unscrew the two mounting bolts and remove the working cylinder
We install the parts in the reverse order, having previously lubricated with grease the mating surfaces of the slave cylinder rod and the clutch release shaft lever
Upgrading the system
Bleeding the hydraulic clutch
Pumping the system after depressurization, and after changing the fluid
Also, if the clutch is not completely disengaged (leads) when the pedal is pressed all the way down, which is accompanied by a characteristic grinding of gears when reverse gear is engaged
Check the level of the working fluid in the tank, if necessary, top up the fluid to the norm
Remove the protective cap from the air bleed valve on the clutch slave cylinder
We put a hose on the valve and lower its end into a container with a small amount of brake fluid
Ask an assistant to press the clutch pedal four to five times at intervals of 2-3 seconds, and then keep it pressed
Unscrew the valve 3/4 turn. Liquid with air bubbles will flow from the hose into the container
Repeat the operations several times until the fluid exits the hose without air bubbles
During the duration hydraulic reservoirs, you need to check the fluid level in the reservoir
The level must not be allowed to fall below 25 mm from its bottom
We twist the valve, put on a protective cap and, if necessary, add liquid to the master cylinder reservoir
