My mother in law has a 1990 camry, I think it is anyway. Her car drives fine for ten minutes, then it gets this strange shaky rubbing sound on the front right passenger side. I pulled the wheel and the brakes. The brakes are wearing unevenly from one end of the pad to the other. Also I pulled the driver side brakes and saw they were fine. The passenger side brakes are also very thin. The rotor looked fine and the wheel bearings and suspension tested fine. I noticed the dust cover was rubbing a little so I gave it more clearence. I don't know what else to do and I want to know why these brakes are wearing so unevenly from side to side and wheel to wheel.
