That's great to know if I ever have that problem. I installed new rotors and pads on my wife's 4dr 02 GT and the front left is making a constant grinding/bent rotor/thud thud thud thud and is really annoying. This being about my 10th brake job on a W-Body car Intrigue/GP's i know what i'm doing. Her car does have a broken front left coil spring the same brake making the noise. My question is....would the broken coil spring cause the wheel to have a camber to it causing the noise or is it just a little bit of a warped rotor? It did seem to get better as I drove it. Maybe i'm just paranoid and it will go completely away as I get more than 2 miles on them. Any ideas would be well appreciated though.
