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 analyzer).

In event of larger deviations of wheel circumferential force: READJUST HANDBRAKE .

Braking with locked wheels must be possible with the handbrake.

The handbrake must be readjusted if the actuation stroke is greater than 6 teeth.

NOTE:

The handbrake can only be adjusted correctly when the parking brake Bowden cables and all moving handbrake parts are free to move and fully operational.

Basic handbrake adjustment is necessary:

In event of excessive actuation stroke (6 teeth).
When replacing parking brake Bowden cables
When replacing handbrake lever.
