Rear brake seems to be working ok, except for noise. When I apply it I hear a clunk and sqeal. The pads, upon inspection look normal the rotor shows normal wear. I did observe the rear rotor wiggles a bit on its mounting as does the caliper. The fronts are mounted snuggly. Is the rear what is know as a floating rotor? Somebody run out and give their rear rotor and caliper a shake and let me know if it wiggles. Not sure if I have a dealer issue here or not. I read changing to a different pad may help. I have never seen a rotor and caliper that wiggles before perhaps I need to check the torques on the caliper pins. Dont know any info would at least give me piece of mind.
