Seems like most companies on here powdercoat the brembo calipers as part of the refurbishing process, how does that hold up when putting some heat through them on trackdays?

I haven‘t managed to turn mine brown in the few track outings I‘ve had so they don‘t look too bad for their age but I‘d hate to have them refurbished just to mess up the coating!

Not according to Brembo, but if you want them shiny, it's the toughest. I've always had alloys wet painted because of similar concerns. Too many cycles of heat.

Yeah, I saw they have an article on the brembo website talking about paint and not to use other companies but the arguments seemed pretty flimsy and at no point did they say anything about concerns of the heat cycles of powdercoating. I just wonder if the powdercoating itself would withstand the high brake temperatures.
Surely someone on here must have found the limits!

How much power are you running and how heavy are you on the brakes?You can cook a Brembo caliper on track regardless of the paint finish as they are quite a heavy/bulky caliper,and they are not the best at dissipating heat....it's still a very good caliper though!.SJ.

We powder coat calipers , have done for years , and don't find it a problem , it's baked on at 180 degrees centigrade , so be very surprised if your caliper bodies got anywhere near that temperature , the original Brembo calipers are not powder coated , and will turn brown with hard track use , powder coated calipers we do don't.
Powder coating is a lot harder wearing than wet painting , and you can get some real nice finishes as well

I have seen red powder coat turn pink Ian on one track day,but that was on a friend of mines Evo with 500+bhp,just to add it was not a caliper refurbed by yourself it was another companies powder coating attempt so not on your level Ian.SJ.

Just over 330, can‘t see myself going for more than 400 in the future. Ideally I‘m as heavy on the brakes as the equipment will allow me, but there‘s limits of course. Cooking the finish would be lame. Like I said I haven‘t managed to turn them brown yet so maybe I‘ll be ok.

That‘s good to hear that you haven‘t had problems. Of course every coating has a limit wether paint or powder.
180C doesn‘t sound that crazy hot for track temperatures tho. I guess the alloy wheels get hot, too and the powedercoating doesn‘t just fall off.

As what Ian from godspeed said above if the coating is done efficiently you should not get any problems,and he has more experience then me as he refurbs them,so would recommend you getting them done if its from Godspeed.SJ.

Your discs and pads would see higher temps than 180 degrees C , the caliper bodies wouldn't , with the most extreme drivers on track , you would start to get bubbling on the outer dust seals on the pistons , and could even crack the dust seals from the heat , but that's only because they are very close to the ends of the pistons , which are touching the pads , which are touching the disc.
The calipers are liquid cooled , so you would start having problems with the liquid first , in this case brake fluid , which would boil and you'd lose the pedal , the powder coat would be the last thing to be effected
Hope this helps

Great, thanks for expanding on this, so it would take some serious effort for the calipers to get that hot.
