I recently changed the front brake pads, the rotors did not look like they needed to be turned. The sound seems to be coming from one side. I removed the pads and checked the rotors again. There is some evidence of uneven wear on the back side of the rotor. I did npt check this when I first changed the pads. Will this improve or should I have the rotors turned. There is not any pusing or pulling when braking.
