I have a 997 C2 with roughly 9000 miles on it and I've noticed that all four of my stock brake calipers have faded in color from the original black to an irregular grayish color. I am concerned that I may be overheating the brakes, but I have not tracked the car yet and I don't tend to ride the brakes during daily driving. Is this typical, or should I be concerned?
Thanks,
Dave

I have a feeling that you use an automatic car wash.....
And whatever caustic compound they use has etched the paint on the calipers.
I have seen what you describe
It's not from overhating the brakes

My car is 8 months old and I have 9000k + miles and mine are red as well. After at least 50 wheel cleanings the calipers look the same as the day I brought it home. Do your calipers still have a glossy finish? What wheel cleaner are you using? My 996 had black calipers and after 4 years and hundreds of wheel cleanings the clear coat started to peel and where it did the caliper had a grayish hue. I was told that different wheel cleaners I used over the years could have been the culprit. From your description it sounds life the clear coat on the caliper has clouded or peeled off which would give a grayish appearance. This may be a warranty issue but you'll probably have to convince your dealer you didn't use anything to harsh when you cleaned your wheels.

I'd recommend getting the wheels really clean, then hitting them with a coat of Rejex... that way, you can wash with soap and water and reduce contact with potentially nasty wheel cleaners.
Have you tried Simple Green to clean wheels? It- works almost as well as some of the more agressive cleaners...
I'm assuming that the black calipers are wearing a high temp paint like the red ones... it may be an epoxy, I don't know the formulation - regardless, they should not "go grey" on their own.
Just MHO.

I had the same issue, the dealer had the body shop paint the calipers black and stencil on the PORSCHE logo. I was driving a new Cayanne (sp?) with 2k miles and it had the same problem. My guess is this is a defective issue

My selling dealer did it as a favor, I don't think the factory would pay for it.

This happens on all of our cars that we drive in the winter. The salt appears to cause the paint on the calipers to 'grey'. This is one reason the 911 is parked inside during the winter months.
