Bleeding Of Brakes Of Rear Wheels - Zetor PROXIMA PLUS 90 2012 Operator's Manual

2. BLEEDING OF BRAKES OF REAR WHEELS

Carry out bleeding as follows:
1. Check level of brake fluid in the expansion tank. Refill missing volume to the
maximum if necessary.
2. Slide a hose onto the bleeding screw (2) of the brake cylinder after prior removal
of a rubber cap from the screw and sink other end of the hose to the bottom of a
transparent container filled partly with brake fluid (3). The bleeding screw shall be
still under pressure to prevent penetration of air into the system through its
threads. Put the container at least 300mm above the bleeding screw.
3. Release the bleeding screw max. by 1/4 of turn.
4. The bleeding procedure is the same as in Warning, see p. 188.
5. Tread on completely the pedal that is not blocked by the gauge and tighten the
bleeding screw.
6. Release the brake pedal and repeat the procedure until air bubbles stop escaping
from the hose.
