Bleeding Of Hydraulic Clutch Circuit; Foot Brake Check; Foot Brake Adjustment; Parking Brake Adjustment - Zetor Forterra CL 100 Operator's Manual

Bleeding of hydraulic clutch circuit

Bleed the clutch hydraulic circuit in the same way as rear
brake system bleeding. The vent screw of clutch hydraulic
circuit is located at the clutch control cylinder (1).
Add only fresh brake fluid into the brake fluid
tank, which is common for both brake and clutch
circuits.
Brake fluid must be replaced in the entire brake circuit
including the clutch hydraulic circuit after each two
years of operation.

Foot brake check

With the foot brake pedals disconnected depress the
pedal with the maximum force of approx 500 N. If the
pedal can be depressed almost to the stop consisting in
the boss on the bottom part of the console, the foot brake
must be adjusted.

Foot brake adjustment

Before the adjustment of the foot brake the parking brake
lever must be in the unbraked position and between the
nut (1) and pin (2) in the disc brake lever (3) there must be
some play. If you find zero play, loosen the nut (1) slightly.
Lift both the rear wheels and instruct your assistant to turn
one of them by hand. At the same time tighten the
adjustment nut (4) until the wheel cannot be turned. Stop
tightening. Then, loosed the adjustment nut by 5/6 of
a turn (5 tabs of the nut) and check the turning of the
wheel.
After this basic adjustment check the operation of the foot
brakes to see whether the braking effect of both the
wheels is the same. If not, loosen the adjustment nut (4)
by the required value on the side where the braking effect
is higher.

Parking brake adjustment

The adjustment of the parking brake follows after the
adjustment of the foot brake. The parking brake lever must
be in the unbraked position. Perform the adjustment in
such a way that the self-locking nut (1) of the parking
brake draw-bar can touch the pin (2) in the disc brake
lever (3).
After this basic adjustment check the operation of the
parking brake to see whether the braking effect of both the
wheels is the same. If not, loosen the adjustment nut (1)
by the required value on the side where the braking effect
is higher.
