BRAKE PAD ROTATION????

2006 Volvo S40

Brakes problem
2006 Volvo S40 Front Wheel Drive Automatic 33000 miles

Had my car to the dealership today becasue I continue to hear a clunking sound when I begin to drive forward from reverse. I hear " something spinning" and then hitting something that sounds like its coming from the LF end. Had the motor mount replaced with hydraulic mounts after they said that was the problem, but it didnt fix the issue. Now they say the brake pads are rotating within the calipers and THAT is what is causing this sound.I dont know if I believe that, seems that brakes STOP rotation, they do not rotate themselves. Any thoughts on what I am being told here?

You can get a little bit of a sound from the brake pads from them moving back and forth. There is some clearance between the brake pad and the caliper bracket so when you go in reverse, the pad will slide down to make contact with the bottom bracket an when you go in drive, the pad will slide back up and the top of the pads contact point will hit the top of the caliper bracket. Usually cleaning the contact area of the pads and caliper brackets and applying brake grease on those areas will minimize the noise. But there has also being some issues with the front lower control arm bushings in the rear where they beging to split but they make more of a thumping sound when you apply the brakes. If you are still in doubt you may want to go to another dealership or another shop for a second opinion? Keep me posted as to what they find please.
