We will measure your rotors before turning them on the resurfacing machine. If your rotors are not within factory safety specifications we are legally bound to not turn them. In this case we will not be able to do your brake job and return the car to you no charge and no brakes. If your rotors are not within specification and you choose to have us replace your rotors, we will offer you the best price in town on the parts and there will be no additional charge for labor to install them, just the charge for the rotors, since it takes about the same amount of time to install new ones as it does to resurface the old ones. We recycle and would much rather resurface your existing rotors than have them go to the dump.
