cliffcoggin Posted March 22, 2020 Share Posted March 22, 2020 At a complete guess I suspect the ABS system is rapidly releasing the rear brakes because they are locking. Does the S3 have a different brake bias to the A3? Or perhaps the wheel speed sensors are different? Quote Link to comment Share on other sites More sharing options...
Magnet Posted March 23, 2020 Share Posted March 23, 2020 Hell Mr. Newbie, Another pointer to supplement Cliff’s comments:- When you fitted the (non standard?) rear brake discs, are you absolutely sure the hub mating service was completely free from corrosion, which might result in the discs not sitting properly on the hub? Vitally important consideration, as you probably appreciate. Perhaps you could let us know. Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
