Brakes and Traction Control: Service Precautions

Brakes, Testing

General Information

• The testing takes place on a test stand.

• During testing, automatic transmissions must be in the "N" position.

• Always follow the instructions provided by the test stand manufacturer.

• When the ignition is switched off the brake control system does not work.

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.

Regulated 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.

This prevents the brake forces from being transmitted into the driveline.

During testing, the wheel turning forward is measured, therefore 2 braking tests are necessary on each axle.

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

Test stands approved by Volkswagen meet these requirements.
