I'm fairly sure the rotors aren't warped, you probably got oem pad deposits all over your rotors so they replaced them since BMW doesn't turn rotors. I bet you got a one time good will replacement.
I was talking to a brake engineer for a major supplier at COTA and he told me modern iron discs are very difficult to actually warp. I thought I warped my rotors but ended up being pad deposits from running stock and then track pads on top causing an uneven wear layer.
I used a rotor hone to clean off all the deposits and re-bedded pads and it was fine. |
I have a pad deposit issue now on my M2. What exactly is the procedure to fix this problem short of throwing new parts at the car?
