I posted a few days ago about my brake pedal vibrating when braking, most everyone said warped rotors. I had both the rotors and brake pads replaced by a reputable shop, now the vibration is worse, and whenever I brake (from whatever speed) a terrible grinding sound comes out of the rear, brake pedal vibrates, and when below 5mph, hear a sort of grind-clicking(?). When I start to accelerate, I hear a faint grinding sound but then goes away. The shop said the rear passengers side brake cylinder is leaking brake fluid and that's why the pedal is soft. Would this cause this kind of vibrating? I had them replace a tire on that wheel as well, could they have damaged something when doing this? I can still break, I give myself extra distance, but still a bit scary to brake now
