A few weeks ago from out of nowhere I started getting this sound of metal on metal coming from my front passenger wheel area. The noise would only STOP when I applied the brakes. It was also a rotational noise, starting and stopping very quickly. I pulled the tire and found that the rotors and pads had an uneven wear. The wear formed a serious groove shape over the width of the pad and rotor.
I replaced both front rotors and put in new EBC greens today and went for a break in drive. After about 5 minutes the same problem started again. The noise only goes away when the brakes are applied.
I've never seen a stuck brake caliper piston before but it sounds possible to me. I'm not positive it's not a bearing, but the fact that it stops when I apply the brakes makes me think a bearing is not the culprit. The uneven wear pattern from before did seem like it was happening because of too much force coming from the area directly under the piston.
Any suggestions? How would you test a caliper piston?
