About a month ago something in the rear of my car started making this high-pitched squeaking, metal on metal noise when I was reversing. Not constantly, but like something turning was binding and releasing, binding and releasing. I only had the rear bearings replaced 6 months ago, so i hoped it wasn't that.
With the car up on stands and the rear wheels removed I've isolated it to the driver's side rear wheel. If I turn the rotor by hand it rotates freely and then gets really hard to rotate, and then gets easy, and so on. My first guess is that somehow I've warped the rotor. Does that sound right? I've never tracked the car, but I do ax it. Or could it be something else? I have the 5 lug conversion, so I believe they're off a 911.

Pull the pads out and see if the noise continues. If so, inspect where the rotor goes through the caliper. Might be the edge of the rotor rubbing on the bridge of the caliper; this happens when you use Six rotors (solid) with -4 calipers. Might also be happening with your mix of parts.

Check both top and bottom of rotor for clearance. I think I have about 3mm on each side. |
