I have a squeaking from the front passenger side. It only seems to happen when the brakes get some heat in them, say after 3 miles of driving.The squeaking goes away when turning right, and gets louder when turning left. I've noticed a ring on the right front rotor. I did a full brake job about 1,000 miles ago but just yesterday I put on new front brake rotors to see if that would help and it didn't. Anybody have an idea of what this might be. Wheel bearing possibly?
