Brakes Inspection, AWD
WARNING: This page does not describe the selected car, but rather 23 other vehicles, including the 2017 Audi S5, 2017 Audi A5 Quattro, 2016 Audi S5, 2016 Audi A5 Quattro, and 2015 Audi S5. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Test on a one-axle roller test stand for all-wheel drive vehicles.
During this test, the wheels of one axle are driven in opposite directions, to prevent delivering power to the other axle.
The test speed must not exceed 6 km/h, otherwise, the brakes may lock up due to the roller start-up delay (EDL regulation).
WARNING:
If the test speed exceeds 6 Km/h the Torsion differential will be destroyed!
Test stands approved by Audi meet these requirements.
