So less then a month ago I had all new EBC USR rotors and redstuff pads (bought them off Amazon) installed by a local mechanic who I used for years with all my other cars and never a problem. I moved to a different area for work and started to feel when braking from 60-40mph a vibration. I took it to my new local dealership out of not knowing anyone else in the area yet to trust. I dropped off my car and explained everything and asked if they would test the run out and true the rotors and I was told they would. They said to me the rotors were "out of round" and needed to be replaced. When I picked up the my CX-9 I asked them for the run out print out and they said they didn't do that. When I asked how they trued them they said they were warped because when they stepped on the brake it vibrated through the pedal and not the seat. These brakes are high end and I have used EBC on all my cars without them "warping" or even as much as a vibration. Now a couple questions:
1) Does Mazda have a document stating what must/or should be done to determine a rotor is warped or needs to be replaced?
2) Is it even likely that rotors could "warp" in 1300 miles of use?
3) I've read a lot recently about how rotors don't "warp" but just need to be trued from a run out, how would cast iron wrap anyway?
