BLEEDING THE REAR BRAKE SYSTEM
− Check the level of the brake liquid in the expansion tank, replenish it with the fresh
liquid to the maximum level.
− Put a hose on the bleeding screw of the brake cylinder and submerge its second
end to the bottom of the transparent vessel partially filled with brake liquid.
− Depress the brake pedal, loosen the bleeding screw through 1/4 turn as maximum,
depress fully the pedal, and tighten the bleeding screw again.
− Release the brake pedal and repeat the procedure until air bubbles stop escaping
from the hose.
In the course of bleeding monitor the
amount of liquid in the expansion tank
for avoiding aspiration of air (A).
Keep the hose end submerged in
the liquid continuously with hold-
ing the vessel as high as possi-
ble (B). After two years, the
brake liquid must be exchanged
in the whole braking circuit:
