How could the calipers handle the temps of braking but not baking? Are you baking ?

I’ve read that powder coating calipers is not recommended for calipers. My preference is to powder coat my calipers due to the fact that I have a great powder coater nearby. However I am tracking the car so I am concerned about its ability to withstand the heat. Anybody successfully powder coat their calipers for track use?

Who says that?

Paint not Powder

We get the calls daily “Can you powder coat my STI calipers purple”? No. Here’s why; as mentioned above, the calipers are completely assembled prior to painting. The assembly process requires assembly lube. The powder coating process involves heat over 450 degrees. If you’ve ever powder coated something, “out-gassing” is a real thing. Try powder coating a control arm with an old bearing in it. The heat causes the grease in the old bearing to liquefy and melt out, ruining your finish. Assembly lube does the same thing. Now let’s revisit “reinventing the wheel”; these calipers were meant to be painted, not powder coated. Powder can be too thick causing pad fitment issues (yes, we know people who have to grind their pads to get them to fit). Let’s Segway into paint.


I think I saw something on Brembo’s site too, can’t find it now.

Well you don't powder coat them with the seals/fluid in. Nor do you powder the insides (like the pad pins) where a thick coating would impede movement nor do you coat the mounting surfaces.

Here’s the other one:

Brembo does not recommend repainting calipers due to the potential issues that can be created when done incorrectly. If you choose to paint your calipers regardless, please read below.

Special Notes:

• Brake fluid, harsh brake or wheel cleaners can damage any caliper finish.
• Powder coating is not recommended.
• Two piece calipers should never be taken apart.
• Pistons should not be removed.
• Stiffening bridges, stainless abutment plates or any other parts that are not listed below should not be removed.

Seems you all disagree, which I prefer, but that was part of my question. By this I take that you have successfully powder coated calipers without problem for a track car?

Wait wait wait, brembo wants you to spend $8k on new brakes rather than refurbish old ones?

[Mattn1192]

There’s nothing wrong with removing ur pistons. Safety is what you should be focused on while doing it IMO. Just seems like a way for Brembo to make more cash, which I don’t blame them. But you can disassemble the whole caliper, get rid of all the fluid in it, then blast to remove whichever paint is on it. Rebuild. Powdercoat. Good as new. That’s what I’m currently doing.

No, Brembo doesn't want to have to deal with people who do stupid shit with their calipers then try to get customer support. If you do what you do to a caliper and it works out, that's great. But if it doesn't work out, Brembo doesn't want to hear from you.

[Maxhouse97]

Ok great, on top of this I had my local powder coater say he didn’t do calipers as well, so all added up and caused me to ask. I suspected like most here that the finish would have no problem standing up to the heat on the track (my main concern was the finish).

Yes agree when they say we don’t recommend refinishing at all … both money and safety involved in that 😊

[Tbonem3]

So stick with stock brakes then, they're good as is.

FWIW, I purchased a set of Porsche 996 Brembos on eBay, completely stripped them, masked appropriate areas, placed bolts in all threaded locations, got them powder coated, and reassembled with new seals and hardware. Reinstallation went smoothly and haven’t had any issues during operation.

So I’m coming back to the well again to see if anyone has any tips or tricks to eliminate or reduce front brake squeal when the brakes are hot (zero noise when cold). It is so loud that you cannot hear the radio and everyone stops to look to see where the horrible noise is coming from. I also have a Macan turbo which was referenced in the Porsche bulletin that was shared in this thread and the two sequels are worlds apart in both tone and volume with the Macan being very tolerable and in no way a nuisance. Thanks!

I have done,

-new shims
-coated all metal on metal pad to caliper surfaces with anti squeal coating
-moved from stock brembo pads to akebono ceramic pads (which claim zero noise)

What seals did u go with?

I did Brembo or Porsche parts for everything. Seals specifically were genuine Brembo. They were harder to source but I found a race shop online that sells them.
