ok problem is that when we changed calipers and rotors i don't think we got something tight... i'm not quite sure though...but what i get when i am driving down the road is a loud click sound when i go over a bump even a tiny one... we took the wheel off and saw that it is the caliper making this sound...the bolts that hold it on the rotor aren't flush so it hits the caliper... anyone know how to correct this?
