Only thing I know is 90 percent of what people call warped rotors is really pad residue on the rotor. Turning does fix the problem. Pretty darn hard to warp a large rotor like the ones on the front, and the back brakes do so little on normal stopping that can't understand how they get overheated enough to warp.
Have not heard anything, and I have 17K and no brake problems or noises. In fact, the only noise I have is behind the new NAV system, and I would bet it is the adapter vibrating.
If we are having problems with rears heating up and warping, I would have the dealer make sure the park brake is adjusted correctly after the brakes are repaired. If out of adjustment, the brakes will be too tight, apply too much pressure to the rotor and overheat the rotor (and the pads).
I will add that I will not use factory pads when I change the brakes (if I keep it that long
). Factory pads SUCK, since they cannot use asbestos.
So, the pads are made with other organic materials that tend to cause them to wear too fast, and tend to leave residue on the rotors when heated up (mountain driving is good for this).
I'm hoping someone comes out with a low dust, kevlar pad for the H3 before I have to change; if I have to change.
