[QUOTE="Michael Cacioppo, post: 556846, member: 57235"] In my opinion, rotors that are stessed relieved after machining should not readily warp if the stresses applied by the lugs are uniformly applied. Brakes and rotors should be what is called "bedded" to insure a good pad/rotor interface. Pad material actually covers surface of the rotors uniformly. Most people don't bed their brakes which I believe contributes to high spots, much of which is pad material. This aggrevates the warping procedure isasmuch as the applied heat pattern no longer is uniform when braking. Cutting rotors reduces their thickness and mass and contributes to higher brake rotor temperatures since the heat sump (rotors) no longer has the same capacity. Most of the time if the original had more than amble mass, this is not really a large factor. You are right about the rip off prices that many places charge when brakes are involved. as you know the job is not that difficult and rotors usually do not require cutting if they have not been warped. That's my opinion. [/QUOTE]
