Brakes and Traction Control: Testing and Inspection

Brake Testing With AWD, Testing Via Haldex Clutch

Testing with an Opposite Running One Axle Dynamometer

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

This prevents the brake forces from being transmitted to the drivetrain.

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

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

The Volkswagen approved test stand fulfills these conditions.

Testing with Standard One Axle Dynamometer

- Drive the vehicle forward onto the rollers.

- Turn off the engine and wait 2 seconds.

- Perform the braking test.

- Start the engine and wait approximately 5 seconds until there is enough vacuum.

- Drive the vehicle forward until the rear wheel are resting on the rollers.

- Turn off the engine and wait 2 seconds.

- Perform the braking test for the rear brakes.

- Start the engine and wait approximately 5 seconds until there is enough vacuum.
