Test on a single-axle brake dynamometer for all-wheel drive vehicles
The rollers drive the wheels of one axle in opposite directions to avoid transmitting torque to the other axle.
Test speed must not exceed 6 km/h, otherwise the EDL control can activate the brakes if the rollers start at different speeds.
CAUTION:
The Torsen differential will be seriously damaged if test speed exceeds 6 km/h.
All brake test equipment approved by Audi meets these requirements.
