Air in the clutch hydraulic drive is indicated by incomplete disengagement of the clutch, as well as "softness" And "failures" clutch pedals.
1. Clean the tank and bleeder from dust and dirt.
2. Check the fluid level in the hydraulic drive reservoir and add fluid if necessary.
3. Put 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 vessel with hydraulic fluid (30–50 g).
4. Unscrew fitting 9 by 1/2–3/4 turn, sharply press and slowly release the pedal until air bubbles from the hose stop.
5. Pressing the pedal, tighten the fitting to the full. Remove the hose and put on the fitting cap.
6. If, despite prolonged pumping, air bubbles come out of the hose, check the tightness of the fastening of the connections, find out if there are any cracks or leaks on the tubes in the connections with the fittings. It is possible for air to enter through damaged O-rings in the master or slave cylinders.
7. When pumping, the fluid level in the hydraulic reservoir must be above the opening of the tube connecting the reservoir to the clutch master cylinder, the end of the bleeding hose must be constantly immersed in the liquid.
