Brakes and Traction Control: Service Precautions

Brakes, Testing

Vehicles without Electric Differential Lock, Checking

The brake test is to be performed on a one-axle roller test stand.

Do not exceed a test speed of 6 km/h.

Volkswagen approved test stands meet these requirements.

Vehicles with Electric Differential Lock, Checking

Brake test must be performed on a regulated brake test stand driven in opposite directions.

"Moving in opposite directions" means: The rollers on the brake test stand turn forward on the one side and backward on the other side.

"Controlled" means: The speed of the test stand rollers must be regulated in such a way as to avoid any speed difference during the brake test.

The transferring of a force to the rolling wheels in the roller set is prevented by the stationary wheel (outside of the roller set) via the drive harness.

During testing, the wheel turning forward is measured, therefore two braking test are necessary on each axle.

Do not exceed a test speed of 6 km/h.

Volkswagen approved test stands meet these requirements.
