Thanks for your response. Yes, I jacked the car up and rotated the wheel by hand. The mechanic said he put it on the lift, though I didn?t see it. I had to pay the $80, otherwise I couldn?t get my car back.
Your suggestion of a twisted brake pad hanger sounds plausible, but I don?t know what that piece of equipment is. How would I be able to find out if that is the problem? Could I jack it up and look in there myself without having to do a lot of disassembly?
