Just got a 2008 Mini with 23,400 miles on it. From the moment I drove it off the lot everytime I apply the brake it sounds like grinding. Have since taken it back to the dealership and they have replaced the rotors and pads (after market), still making the same noise. They are now in the process of putting factory pads on it. Does anyone have any insight into this? I love the care but this is a bit aggravating.
