.. just got back from my gfs house (2.25am -FIRDAY 13TH!!) and realised a heavy grinding noise coming from my front wheels.. drove cautiously shitting myself and realised the car wouldnt slow down when i hit the brakes! it only makes a grinding noise! i checked the pads, they were fine! what the hell could it be?! the car doesnt fully stop when i floor it on the brakes, it just slows down very quickly
