Parking brake function check

IMPORTANT: Follow instructions for BRAKE TESTING ON TEST STAND .

NOTE: If deviations are identified during the following check, the parking brake must be adjusted:

Drive vehicle onto brake test stand

Warm up brakes.

Check parking brake.

0th tooth (handbrake released):	Vehicles with manual transmission: Shift lever in neutral position. Vehicles with automatic transmission: Selector lever in selector lever position "N". Without locking differential ≤150 N. With locking differential ≤ 200 N (possibly odd display).
1st tooth:	No increase in breaking force with regard to 0th tooth. Indicator lamp can be lit.
2nd tooth:	Indicator lamp must be lit.
3rd tooth:	Increase in breaking force.
5th tooth:	The brake force display must have reached ≥ 400 N.

Checking brake force differential at wheel:

Apply parking brake until a wheel circumferential force (measured on brake test stand) of min. 1000 N is reached.

Max. permitted brake force differential right/left ≤50 % (referred to greater brake value).

Breaking with locked wheels must be possible with the parking brake.
