4.2 RELEASING THE PARKING BRAKE
WARNING!
- Never release the park brake on
an incline without precautionary
measures.
Releasing the park brake on an
incline causes the vehicle to move
unintentionally. This can lead to
serious injury and damage to the
vehicle.
1. Place wheel chocks in front of and behind the
wheels.
NOTE: It is not permitted to use a
socket wrench to loosen the
releasing bolt.
2. Turn the releasing bolt anti-clockwise as far
as the stop using a ring spanner.
3. Carry out this operation for each spring
brake cylinder.
NOTE: Place a no brakes warning
label on the steering wheel.
4. Bring the park brake back in operating order
by turning the releasing bolts clockwise as
far as possible and tightening them to a
torque of 45 Nm (75 Nm for the releasing bolt
with control pin). The pressure in the spring
brake cylinder circuit must be at least 6.5 bar.
