" Powder-coat painting is not a process you should use for brake calipers"
really?? I'm sure there's at least 100+ of us on here that can prove that wrong

My car is crazy unsafe with its powder coated calipers now...

Oh yeah. Metric powder is a bitch. You need to heat the oven in degrees Celsius. What was I thinking?!

all cars out of factory have a sticker finish. NOT PAINT. its super dangerous to use paint on anything now a days.

I ended up reading into something Brembo wrote and it mentioned that using a powder coat paint process on their calipers is not recommended. Powder coating traps heat in.

$20 for a set of stickers? That's gotta add like what, 15hp?

That simply is not true. They do not recommend it because why would they? It is in NO companies best interest to recommend or support you in disassembling their product and rebuilding it (outside of the factory or authorized service location). Especially not brakes. It's far too much liability. But that doesn't mean it cannot be done.

Powder coating does not trap in heat. It is not some magical coating. It has many of the same properties as paint. However, it is typically much more durable than paint.

Think about what your saying. It is physically impossible to "trap heat in." Since brakes are designed to work at extremely high temperatures, it's not even reasonable to say that the baking process changes the properties of the metal in any negative way, because repeated use of the brakes would have the same effect.

Isn't paint not particularly great at promoting heat transfer vs bare metal? They do make special paint for heat exchangers so I had assumed so. Now does it matter to the average joe, probably not. I'd powdercoat the heck out of my calipers to keep them shiny even if I do track days. But I could see how some labcoats over at Brembo are not going to encourage the practice.

I realize it is pretty much a non-issue but you two last posters are making it like you've never heard of an insulator...ooh it must be magical...its physically impossible for any material to "trap heat in" i.e. all material known to man has the same thermal conductivity...that is about the dumbest thing I've heard this week. An kpluiten you been around here for a while...I thought you were a smart d00d with this stuff.

What are you on about? Of course I know what an insulator is. Of course I know that different material have different thermal properties. In fact, I study heat sinks all the time in the course of my day to day job. No one said that all materials have the same thermal conductivity.

Powder coating is typically applied at a thickness of 0.001-0.006" thick. The average human hair is 0.002" thick. So we've established that properly applied powder coat is relatively thin. Paint is typically applied at nearly the same thickness range. Have you ever stripped Bembo calipers? I have. The paint is THICK. In fact, I found it to be as thick as the powdercoat I replaced it with. Neither coating has any sort of ceramic additive (they can, but neither the Brembo paint nor typical powder coat does).

So the point of all this rambling is that it is my firm opinion based on the facts, that powdercoating in this instance does NOT insulate the caliper to any significant degree more than the OEM paint. Which is what I said in my previous post.

Furthermore, in a brake system, the ROTOR is the primary heat sink. By design. The caliper absorbs/transfers far less heat than the rotor. In fact, manufacturers go through great pains to try to keep it this way. The put the binder material on the pad in the caliper, not on the rotor (with steel plates/pads in the caliper). They put titanium shims between the pad and the pistons in the caliper. They make the pistons ceramic as to not conduct. My point is that the caliper plays a minor roll in heat dissipation for the system. Go touch your caliper after a drive and touch your rotor. Tell me which one your fingers stick to. The caliper still heats up, but to a much lesser degree. Powdercoat isn't going to impact the system to any measurable degree.

You could have just stated it that way in the first place. I know you are an engineer, I thought you should be more accurate rather than spouting off about magical coatings. "Sure it insulates to some degree but its too thin to matter in a practical sense" was how I thought of it, looks like we are in agreement.

I was addressing KrazyKarls comments too so that wasn't all attributed to you.
