34 00 012 Parking brake function check
Perform inspection in the following manner:
When 1st ratchet is engaged, no braking force should be exerted.
The difference in wheel circumferential forces between the left and right wheels may deviate by max. 30 % from the greater value (measured on brake test stand).
In event of larger deviations of wheel circumferential force: READJUST HANDBRAKE .
It must be possible to lock up the rear wheels by braking with the handbrake.
The handbrake must be readjusted if the application travel is greater than 6 notches.
NOTE:
Proper adjustment of the handbrake is only possible if the handbrake cables and all moving parts of the handbrake mechanism move easily and function correctly.
Basic adjustment of the handbrake is required in the event of:
- In event of excessive actuation stroke (6 teeth).
