I'm hearing a stange noise coming from at least the right rear of my GXL when driving (it may also be coming from the left, but I'm not sure). I assume there is something wrong with the rear brakes. The noise sounds like a flat tire, and like a flat tire it's intermittent and increases with speed. It's not a flat since the rear tires are fine and fully inflated, and the noise changes pitch when I press the brakes. It's probably related to the brakes. My best guesses are:

a) A (really) warped rotor
b) Incorrectly installed pads

The P.O. said the rear rotors are Brembo OEM type and the pads are Hawks. I'm going to e-mail him and ask for some more detail, like how long ago the pads/rotors were changed and by whom. Any help would be greatly appreciated.
