so i replaced the front pads and rotors and at the time my mechanic told me the rears were good for another 30k. Well he was wrong and now i have all this brown gold dust onto my wheel which is really hard to remove and not sure how to get into the groves to clean them. ive got Volks. anyone ever have this problem? it looks like the pads are completely worn and its digging into the metal of the pads. needlees to say my rotors are crap too but i am replcing them tom as well. HOW DO I CLEAN THEM THE RIGHT WAY. IVED TRIED SEVERAL THING BUT NOTHIN WORKS WELL. THANKS RX
