Thanks for replying randy. I know its difficult to diagnose the problem over the Internet but I dont know where else to look. I have tried taking the wheels off because I also thought the rotor might have been tilted as you said. The noise is kind of intermittent. This morning it was 30 degrees and I drove 50 miles to school and it was fine. Yesterday coming to and from work It was doing it. I do think they might have cut the rotor down too much but I'm not sure. I think if the dealer would replace the passenger side rotor it would be good since it seemed to fix the other side. By the way I drive the car easy, and it still makes the noise while slow and medium braking. It doesn't squeel. And I'm pretty sure it is the rotor because the noise goes with the same speed the wheels are turning. Does that make sense? I guess I will have to wait until the 9th and see what the dealer has to say. The best way to describe the noise would be like a rocking chair rocking back and forth. Thanks for your input
Yeah, it does sound like the noise is related to the rotation of the rotor. I takes less than 10 minutes to replace a rotor on that car. I would think the dealer would just replace the rotor and see if that fixes it.
Legally, the rotor can only be turned down so much according the thickness spec. range, I believe that is DOT law. Any good brake shop should mic the thickness before and after it's turned. I've had a brake shop, say "no they are too thin to turn" and they would be out legal spec. I then I took them to another shop, and they turned them with no problem.
I am not a machinist, but I would think that the amount that needs to be removed from the surface is just very small, enough to smooth the surface, or correct any warp. Usually, if the rotors are warped, due to excessive heat, turning them will NOT fix them, they will warp again almost immediatley.
Keep us posted. Good luck.
would my problem more than likely be that since the rotor is too thin it is moving while braking?
