So it sounds like "harsh" chemicals were used on the calipers and caused them to "fade".
Leading evidence: 'Use on the calipers and caused them' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'previous owner having spilled brake fluid' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Clean calipers' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I use Testors 1103 Red model paint to touch up the small chips, and Krylon or Rust-Oleum 7701 crystal clear spray for the clear coat delamination.

mea culpa, I have used wheel cleaners in the past!

Suspected cause
The calipers on my 4s were like that (faded with clear coat peeling)- always thought it was due to previous owner having spilled brake fluid on them while bleeding the brakes etc.

Suggestion
So what's the conventional wisdom on this board on the "Porsche" logo on the brakes (assuming it has faded and needs to be redone) - use a stencil and spray paint, or apply decals?
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

All,
I'm looking at a '02 C4S and I have a question in regards to the brake calipers. The factory calipers are powder coated red. What would cause the red to fade on various parts of the caliper? Is this normal? Or is it from a lot of 'heat cycles' from the tracking the car? (owner says he never tracked the car).
I would assume the powder coating would not fade.
Thoughts?
Thx!
They should stay nice and red unless they get real hot and then they go black via a maroon color. If they are not red then they have been real hot, and easiest way to get them like that is the track...
Fading... Not sure what would cause that, mine look like new, never been repainted
S -should be a red caliper.
My silver ones(C-4) are faded in places, not pristine anymore.
Seems like the brake dust has affected the paint.
Also flushing the brake lines getting brake fluid on the paint of the caliper
may change the gloss of the paint.
All four of my calipers have faded in places and have some clear coat peeling off. I think it's a fairly common issue. I try to clean it up the best I can with the wheels off every now and then. I also wax them on a regular basis, which really helps. Eventually, I will remove them and have them rebuilt and professionally refinished.
If they look like they have patches of flat red on them now, that is because the clear coat has flaked off. It is a common problem with the brembo calipers. It happens all the time to my calipers, and what I do to fix it is to feather the edge of the clear coat delamination with some 1500 grit sand paper, and then give the affected area a spot shot of Kyrlon clear enamel. After it dries, you can't tell there was a problem.
So it sounds like "harsh" chemicals were used on the calipers and caused them to "fade". It looks like it's on all 4 of the calipers. I thought powder coating was suppose to be pretty darn abuse proof! Ugh, removing it and sending it out for powder coating would be a PIA...
For the folks that are "touching" up their calipers, how is that lasting? I assume you're doing this on the car and not removing the caliper, etc..
I don't think factory calipers are powder coated. I believe they are painted.
Even if I have mine refinished, I plan to go with paint. Powder coating is nice, but it's not any better than paint in some applications.
The calipers on my 4s were like that (faded with clear coat peeling)- always thought it was due to previous owner having spilled brake fluid on them while bleeding the brakes etc. I bought the car that way and never bothered to repaint. It wasn't a garage queen and thought it looked good with a little wear. ;-)
The 4s calipers are red. I find it odd that some have the dark maroon discoloration due to track use. I've been to the track countless times and I've never gotten the darkening of the calipers, and I'm a heavy braker/late braker too.
Odd. New fluid each time though and track only pads.
Mine are peeling also, apparently its a very common problem with red Brembo calipers on all makes and models. To be honest, it really does not bother me too much.
I use Wurth/saBesto "GL Laquer Spray Pnt". Clean off the loosened clear coat, hit the calipers with caliper cleaner, then give them a shot of this product. Viola!
This approach seems to last for a year or two...then repeat.
