Hello everybody, new guy here.

I have a problem with my 2000 A4 brake system. It all started after I changed my rear rotors and pads. After the change, there was a vibration during braking when comming to a slow stop, less than 20 mph. This vibration does not happen when the ABS light is on, which comes on at speeds greater then 60 mph and stays on until i shut the engine off,then it goes away until I go over 60mph again.

Thought it might have got some warped rotors since I bought aftermarkets. Went to the dealer and bought german rotors. No dice, problem still excists. Just got done cleanding the wheel speed sensors and abs sensors. Still same vibration comming from the ABS module (I think).

Any help would be appreciated.

 

Check for codes also inspect the abs ring on the axle sounds like there is a crack causing it to read improperly

 

Check for codes too it should help point you towards the responsible wheel, however if the toner wheel is damaged or dirty you can get abs operation at low speeds eventhou no wheels are locked up.
