Porsche Brembo 996 BBK conversion

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

Here’s the other one:

https://www.racetechnologies.com/art...ing-calipers-0

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?

[Tbonem3]

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.

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.

Fake news

[jbfrancis3]

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?

[Tbonem3]

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

I have to say that this modification has made me hate my car. The squeal makes me avoid driving it. It is so intrusive. Does anyone know of anything that can be done to fix this or if this is also an inherent problem with Brembo BBK’s in general like this set,

Make sure you are running updated pads and spring kits. Lube all contact surfaces but don't go nuts. Get the sticky dampers that sit on the back of the pad. Look up my post of a Porsche bulletin about why brakes make noise. It's not unique to this mod.

Also remember these pads and calipers were not engineered to function with our rotors. Results will vary. My car squeaks like crazy with genuine Porsche pads. Oh well. The braking is far superior to stock I live with it.

Check your clearances and make sure nothings rubbing

I have these brakes on my car and do not get any squealing. Are you running dampeners? Maybe it is the pads you are running?

Yup those are the numbers.

I actually just saw a Low milage 28k set in near dam mint condition on eBay. Shouldn't need rebuilding I called up the supplier directly and just bought them.

Anyone have any tips on were to source 996 Rear set 996352421 996352422 ?

Are those the caliper part numbers? (responding via mobile, away from my laptop)

If yes, eBay always has these available. So long as nothing major is wrong with them, you're good. You're rebuilding and refinishing them presumably, so the risk is minimal IMO. eBay is where I got mine.
