I just put on all new drilled and slotted rotors and performance brake pads on my 2003 Audi A4 3.0 quattro and my right front wheel is making a pinging noise everytime I go over a bump. I checked all the bolts on the brakes and calipers and I can't figure wats making it?
Anyone have any suggestions?

 

Could be a loose pad. Could you describe the noise as a chirp? If so, I would check that the pads are in there tightly.

 

it sounds like metal on metal hittings
