- Slide a hose onto the corresponding brake cylinder screw and immerse its other end to the bottom of a
transparent container partly filled with the brake liquid.
- Depress the brake pedal, release the bleeding screw by 1/4 turn at the most, further depress the brake
pedal and tighten the bleeding screw.
- Release the brake pedal and repeat the procedure until air bubbles stop escaping from the hose.
During the bleeding observe the liquid level in the
compensation tank to avoid aspiration of air (A).
Make sure that the hose end is continuously
immersed in the liquid and hold the container as high
as possible (B). After two years you must replace the
brake liquid in the whole brake circuit.

Adjustment of free travel of clutch pedal

Correct play between pedal piston rod and main cylinder
piston is not adjusted -play is adjusted by the producer.
Mutual position between the piston rod and piston rod eye
(1) is adjusted so that the piston rod might be maximally
pulled out from the cylinder and simultaneously the play
between the pedal and the upper stop screw (2) might be
0,1 - 0,2 mm. Subsequently the piston rod is fixed with the
nut (3) to piston rod eye. Check eventual deformation of
dust cap after adjustment, in case of deformation correct it
by hand.
