I am down to 35% on the fronts. I am told that translates to about two more oil changes. Rears are 65% which is good for a while. I have read on the forum that the rotors should not be turned on Brembo's so I am wondering what the front rotors and pads are worth to replace. I do not use my brakes hard. I have 25k miles on them. Probably normal for a performance brake.
