SYSTEM AND PARKING BRAKE
For any intervention on the braking system (adjustment
and/or substitution of the brake discs) address to the

Technical Service Centre or the nearest
TEREXLIFT
authorised workshop.
Only for Telelift 4017-4514
The malfunctioning of the braking system may depend
on the presence of air within the hydraulic circuit.
The braking system has some valves to bleed the air in
the circuit.
There are 2 valves per side on the front axle to bleed the
service brake and the parking brake circuits, and other 2
valves (one per side) on the rear axle to bleed the service
brake circuit.
Valve
B
is used for the service brake circuit; valve
A
for
the negative parking brake circuit.
To bleed the circuit of the service brake:
-
Step on the brake pedal repeatedly.
-
Slowly unscrew valve
B
and re-close it as soon as oil
mixed with air bubbles comes out.
-
Repeat the operation until bubble-free oil comes out.
To bleed the circuit of the negative parking brake:
-
Pull the brake lever
C
to engage the brake and start
bleeding operating valve
A
until bubble-free oil starts
flowing out.
-
Repeat the same procedure for both sides of the
axles.
