Rear Brakes clacking

OK, My right rear brake is clacking whenever I turn right at low speeds. The reason I think it is the brakes is that when I step on the brake it stops. Possible causes? I assume the pads are not staying/retracting and are getting twisted and hitting the rotors? How to fix?

I have a 99 taurus wagon.

Have you figured out what the problem is? I just started having the same problem in my 96 Taurus. I am not sure if its the brakes, but it only happens when turning right at low speeds. Please let me know.
