Hey guys I installed the Brembo blanks along with PBR MM pads a couple of weeks ago, and I can't say I am very happy with them. They have started to squeak even when clean and no moisture. Also, when I continuously brake to a slow speed from a high speed, it will start to vibrate and lot and make this loud echo sound. Sounds like the rotor is vertically grooved or something, and the car shakes at a high rate. Anyone else have this problem?
