BLEEDING THE FRONT PROPELLER SHAFT BRAKE
Bleeding of the braking system with the propeller shaft installed in the tractors fitted
with the front driving axle shall be initiated step by step in both pairs of yoke cylin-
ders. One pair of brake yoke cylinders is furnished with 2 bleeding screws (1), while
the other pair has 3 of them (2). For the bleeding uncouple the pedals by moderately
depressing one of the pedals while with the second of them carry out the bleeding of
one pair of the brake yoke cylinders of the circuit I. Then depress another pedal and
bleed the other pair of brake yoke cylinders of the circuit II. After bleeding the front
propeller shaft brake, bleed the rear brake.
CHECKING THE FOOT BRAKE FOR
PROPER SETTING-UP
With the uncoupled pedals of the foot
brake apply the maximum force of ap-
prox. 500 N on one of them. If the pedal
nearly descends to the stop represented
with a lug on the bottom part of the con-
sole, the foot brake must be set up.
