Bleeding the clutch release hydraulic drive (VAZ-2101)

Before pumping, check the fluid level in the tank and add fluid if necessary. Put on the head of the nipple 9 (see fig. 62) of the working cylinder, a hose, the lower end of which is immersed in a vessel with liquid used for the hydraulic drive. Sharply press the clutch pedal 3-5 times at intervals of 2-3 s and, holding the pedal in the pressed position, unscrew the nipple 9 by 1/2-3/4 of a turn, forcing the liquid in the drive together with air through the hose into the vessel by pressing the pedal. After the pedal reaches the extreme forward position and the flow of liquid through the hose stops, tighten the nipple until it stops.

Repeat the above operation until all air bubbles have come out and, keeping the pedal pressed, tighten the nipple until it stops, remove the hose and put on the nipple cap.

When bleeding, make sure that the fluid level in the tank is above the hole for the tube going to the master cylinder, and that the end of the bleeding hose is constantly immersed in the fluid.

If, despite prolonged pumping, air bubbles come out of the hose, then check the reliability of the connections, find out if there are cracks in the tubes or leaks in the connections with the fittings. Air may penetrate through faulty sealing rings of the master or slave cylinder.
