I was in for an alignment jobbie at Firestone and i also needed new brake pads... however the guy there told me that my car and some or most BMW's u gotta change the rotors with the pads, that u dont just change pads only... it cost me $360 for both front wheels, and that was with a "$50 discount"..... so to me $180 per wheel for brake pads and rotors donr sound too bad.. but I'm no expert. They said the pads were just about totally done.
