I was getting a brake squeel and grinding from the front passenger side when braking. I replaced the brake pads twice, rotors twice, new motorcraft caliper, guide pins, all hardware, etc., and the sound still persisted. The Ford parts guy suggested the wheel bearing, and it seems to have fixed my issue now. Took it for a short drive and the sound is gone, finally. Weird that the wheel bearing was giving me braking noises. This car must run on really tight tolerances in the suspension area.
