That is pretty normal. All paint colors fade and change color with the heat cycling you see on track.

My red Brembos on my previous car turned dark and the lettering fades.

Before track:

After track:

These weren't that bad as I didn't track as much. I've seen pretty bad ones where the paint gets burnt and it bubbles off the caliper.

That's fairly extreme.

Wow that doesn't even look like the same caliper

pad changes are faster by a magnitude. it's off and back on with the removable bridge. I know this because I ran wilwood dynapro's that had a similar construction. I can't imagine the pain with dealing with brembos having to take the caliper off EVERY SINGLE TIME there is a pad change.

Also the pads are extremely cheap and are a standard size.

ok if you're balling with brembos maybe you have your own trackside support and your fav shop that does everything for you. Then again you may not be tracking much or at all with brembos lol (note I said MAY NOT

I do know lots of guys who picked up brembos just for show)

it takes about 1min to take 2 bolts off and get the brembo calliper off.........lol

Actually, it is not. We see painted calipers fade like this all the time, some are worse than others. This is what heat does to painted calipers.

That is true, but doing that a couple of times over then you will find yourself pulling the threads right out of the alum. mounting brackets unless you have converted to studs and jet nuts.

In addition, you will almost need another hand to hold the caliper while you compress the pistons and R&R the pads. Try to do that in the pits with hot calipers and you will know what I mean.

I've never seen anyone's like that before. Fading, yes. That's an all out color change!

Obviously they are not pushing hard enough at the track. You will see more of the rear calipers doing this as there is almost no air flow to the rear.

Must be an EVO. I have seen some worse than that, but no photos.

Dartanium · 02-03-2012, 11:28 PM

any updates? 2 cases of same coating problem, wonder if there are more cases out there due to wrong wheel cleaner used? Perhaps the coating is too delicate afterall...

tibra1 · 02-03-2012, 11:49 PM

Why do they paint instead of powder coat thier calipers?.

4sevens.com · 02-04-2012, 06:53 AM

My stoptech trophies just came in. Can't wait to put them on.

My company makes aluminum flashlights with hard anodizing so I know all about it's characteristics. The aluminum oxide (anodized) finish is actually very resilient ceramic-like coating that is much harder than the aluminum allow beneath it. It's very resistant to wear and actually conducts heat better than raw aluminum alloy. It's not a paint or coating but a layer of aluminum oxided. This actually forms naturally - think of it as "aluminum rust" but never flakes off. When occurring naturally it's clear - so you normally don't notice it and would never think that the aluminum is "rusting." The annodization process is just a way to make that ceramic-like surface thicker. Unfortunately hard annodizing may stain easily from oils and grease.

my two cents

kchu221 · 02-04-2012, 10:37 AM

stoptech is known for these issues... my friend that had this problem called and emailed ST but never got any helpful response. all they said was they never had this problem with any other customers... hope you figure it out soon!

STIHLBOLTS · 03-16-2012, 04:45 PM

The bolts you are looking at are correctly called "Socket Cap Screws" They are a hard alloy steel that in most industries are used black or bare (no coatings other than oiled from the factory.) They can come in stainless steel and the alloy can be zinc plated which is what from the pictures they look like to me. You can coat any plain steel bolt in any plateing under the sun to fit a specific application. I can not speak to what coatings ST has coated or had coated the bolts. If regular zinc coating was used and chemical cleaners and regular wet envornment were used then I believe that it's very possible to get just such a result. There are some seriously corrosive wheel cleaners out there that specificly state to stay alway from aluminum surfaces in the disclaimer part of the bottle. The only other way to go would be to use a hardend strained stainless in the 300L family of bolts to achive the heat resistance and not cause embritlement on a standard commercial stainless bolt. They are a expensive option if you can find them.

How is that Stoptech known for this issue when only a few individuals are involved and may have involved the use of chemical wheel cleaners?

Yes, I had two Evos, an Evo 8 and an Evo 10... both did the same thing. It's like a badge of honor. You can tell who really drives their car when you look at the brake caliper.

Zzhou · 03-29-2012, 12:28 PM

OP any update？ does stoptech helping you?

maaicher · 03-29-2012, 02:20 PM

Stop-tech replaced all my bolts and I reinstalled everything last week. I only have one picture I will try and get some more up this weekend. They didn't do anything about the finish but I did not expect them to. I wasn't asking for them to warranty the bolts after a certain point, all I wanted was to purchase them. After months of calling for the parts list and getting no where it took the OP's and my posts to get them to act. In the end they replaced everything for free so i guess overall I am happy with the outcome.

4sevens.com · 03-29-2012, 08:25 PM

^ did you even try to wipe it down?

Here is mine after 3000 miles and a couple trackdays (160mph down the back straight of VIR).

I just washed my car and noticed the calipers looked dirty, removed the wheels and wiped it down. I only used soap and water. It's a good as new.

I think maybe you guys are using cleaners that are too abrasive.
