Bleeding the clutch hydraulic drive (VAZ-21051)

Air in the clutch hydraulic drive is indicated by incomplete disengagement of the clutch, as well as "softness" and "failures" of the clutch pedal.

1. Clean the tank and bleed nipple from dust and dirt.

2. Check the fluid level in the hydraulic reservoir and top up if necessary.

3. Place it on the head of the fitting 9 (see Fig. Slave cylinder and clutch release fork) working cylinder hose and immerse its lower end in a container with hydraulic fluid (30–50 g).

4. Loosen nipple 9 by 1/2–3/4 of a turn, press sharply and smoothly release the pedal until air bubbles stop coming out of the hose.

5. Press the pedal and screw the nipple all the way in. Remove the hose and put on the nipple cap.

6. If, despite prolonged pumping, air bubbles come out of the hose, 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 damaged sealing rings of the master or slave cylinder.

7. When bleeding, the fluid level in the hydraulic drive reservoir should be above the opening of the tube connecting the reservoir to the clutch master cylinder; the end of the bleeding hose should be constantly immersed in the fluid.
