I recently replaced my brake pads on all 4 wheels. I followed the DIY sticky to the letter. When I finished the job, only the passenger front wheel is squeeking loudly. I removed the pads, repasted them, and reinstalled. Same squeeking. I replaced both front rotors. Still the same wheel squeeks. I give up! Could it be the caliper? If so, should it replaced the caliper or attempt to rebuild?
