 Danger !

Risk of death caused by limbs being caught or crushed by rotating parts when performing tests on the brake test stand

Never leave the vehicle unattended on the rollers except in an emergency. Ensure that no one is under the vehicle or near rotating parts during testing. In case of emergency, use the EMERGENCY OFF switch to shut down test stand.

Check

1

Mount pedal force meter onto brake pedal



000 588 05 21 00 Roller brake test stand

WS42.00-P-0006B

 Pay attention to manufacturer's operating instructions.

2

Drive the vehicle on the roller brake test stand



000 588 05 21 00 Roller brake test stand

WS42.00-P-0006B

 Run engine.

3

Gradually apply specified test forces to the brake pedal, and compare the brake force reached on each axle against the reference values

 The reference values must be reached, to enable the specifications for the legally prescribed minimum deceleration to be fulfilled.

Reference values for pedal force in accordance with manufacturer's specifications, reference value method

*BE42.10-N-1001-17M

If the reference values are not achieved:



Determine causes and repair brake system as required.

4

Drive the vehicle off the roller brake test stand.


If the vehicle with a drive axle is on the rollers, drive it off the rollers only when the roller drive is running.
Otherwise, excessive roller acceleration could damage the drive of the rollers.

5

Operate parking brake

6

Turn off engine

7

Remove pedal force meter
