I my rear caliper was stuck and was causing pad wear. So I changed the caliper and decided to go ahead and change rotor. I realized there was a problem when I could hear the rotor making contact with worn pads or so I thought. I did not hear any noise yesterday after replacing rotor pads and caliper, but today the same noise is back. It is like the rotor is rubbing something as it turns. I hope my description of the problem is understandable.
