[QUOTE="SlowSVT, post: 6103378, member: 20202"] That is not entirely true. I admit I don't know much about the pad material transfer to the disc, something that someone just brought up to me in a similar thread last night. The disc surface gets pretty well polished by the pads which would make pad material sticking to them a but difficult but that is something I don't have much knowledge of. But the claim of rotors not getting warped is something I have first hand experience with. I've done quite a few brake jobs due to brake chatter to the point of shacking the steering wheel whenever the brakes were applied. Took the rotors off and had them turned down. On the brake lathe when the machinist made the first skim over the dics you can hear and see the cutter taking down the high spots (working at a Porsche dealership I saw this repeated many times). After turning the rotors the steering wheel shimmy disappeared. It has been my experience that rotors do warp and is the leading cause of brake shimmy. Regarding the runout thing. Not sure if your referring to the bearing, hub or disc but I broach this subject on the post I mentioned earlier. Rather then repeat what was said here is the link to the thread.
