2. BLEEDING OF REAR WHEEL BRAKES
Bleed the system in the following way:
- Check brake fluid level in the equalising tank. Add missing volume of brake fluid
into the brake fluid tank up to the maximum level.
- After removing of the rubber cap, slide a hose on the vent screw (2) of the brake
cylinder and put the hose end at the bottom of a transparent tank (3) partially filled
with brake fluid. The vent screw must be permanently under pressure to avoid
aerating of the brake system through the screw threads. Place the tank minimum
300 mm above the vent screw at this operation.
- Loosen the bleeding screws maximum by 1/4 turn.
- Bleeding process is the same as mentioned in - Important (see page 178).
- Fully depress the pedal that is not blocked by the gauge and tighten the adjusting
screw.
- Release the brake pedal and repeat the process, until air bubbles cease escaping
from the hose.
