A few weeks ago I had my brakes repaired and my exhaust replaced. Ever since my car has been back from the shop, The rear driver side tire area has been making a clicking/clacking sound related to how fast I'm driving (driving slower, clicks are further apart, etc...). It stops when I push the brake pedal, and it usually disappears once I am going over 40 mph. Today, a faint high pitched screeching sound started happening when it was clicking. What is this, and is there any way I can get the mechanic to take the blame if it was his fault this long after the original repairs? Thank you.
You may have a bent backing plate on the back side of your rotor, it may be catching the on tire rotation. I would call and explain the situation to them and request a free inspection, and take it from there.
It does sound like this problem may have something to do with the brakes. It's possible that something is rubbing or loose, which would be an easy fix. Since it is related to the brakes, I suggest having it checked as soon as possible just to be sure your vehicle is safe. If this is a reputable shop that you went to, they should have no problem taking a look at it to find the source of the noise.
