1. Remove the cap from the bypass valve of the wheel cylinder,
from the crankcase or from the proportioning valve (for non-
ABS motor vehicles) and put a special rubber hose (c. 400 mm
long) on the valve.
Drop the other end of the hose into a transparent vessel, no
less than 0.5 L, which is half-filled with brake fluid.
2. Press the brake pedal 3-5 times abruptly, hold it in the
extreme position and simultaneously unscrew the bypass valve
for 1/2-3/4 of a turn to release the fluid portion from the system
to a vessel. After the pedal goes forward up to the stop, screw
the valve. Repeat the operation until bubbles stop coming out
from the hose dropped into the vessel with brake fluid.
3. Once bleeding is over, press the pedal and hold it in the
extreme position, screw the bypass valve (see Annex 2) and
remove the hose. Dry the valve head and put on the safety cap.
4. Add brake fluid up to MAX mark into the master cylinder
tank.
Cover the tank cap. Screw the cap tightly with effort, carefully
to avoid breaking it.
While bleeding add the fluid to the master cylinder tank in
time and do not let the fluid level decrease lower than 2/3 of
the tank volume. Hold the hose end dropped into the fluid.
Check the brake system when driving the motor vehicle. If
the working brakes and their drives are adjusted correctly and
the brake system is bled correctly, full braking occurs within
1/2-2/3 of the pedal travel.
It is not recommended to add the brake fluid collected after
bleeding to the master cylinder tank.
Brake pedal travel
can be adjusted by turning adjusting screw
6 as required (Fig. 9.35). Free pedal travel should be 5-8 mm.
After adjusting tighten the screw nut with the torque of 14-18
N•m (1.4-1.8 kgf•m).
Adjust switches 4 with nuts 7, maintaining an air gap of
no more than 0.5 mm, which is indicated in the figure. After
adjusting, tighten the nuts with the torque of 4-6 N•m (0.4-0,6
kgf•m).
Parking brake system
Wheel parking brake, affecting the brake shoes of rear wheels
(Fig. 9.36).
