Hey guys, so I have STI brembo's in front and thet stockers in the back on my 03 WRX. My brakes make a really loud sqeal, but only when I'm in reverse. So I had a local shop check it out, they took out the front pads and filed them a little around the edges. (I forgot what that process is called.) And for about 30 minutes it was all good, then it started up again. Could I need new pads?
I have 11,300 miles on the car, and the brembo's have only seen about 4k of these miles. Maybe the rear pads only?
