Brake Testing Via Haldex Clutch, with AWD

With AWD, 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 transmission into 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.

The Volkswagen approved test stand fulfill these conditions.
