Default Does painting the brakes (Caliper / Drum) reduce braking efficiency ??

Hi guys,

Just out of curiosity, wanted to know whether painting the brake (Caliper / Drum) reduce braking efficiency ??
OR
Changing the OE colour of the brake caliper / drums reduce braking efficiency ??

Since every colour absorbs or dissipates heat at a different rate.
So would painting or changing the colour of the brake caliper / drum have ANY adverse effects on the braking efficiency or heat dissipation ??

Absolutly no!! these parts are painted anyway during underbody coating.

What does braking in our car has to do with the amount of heat decipation, seriously . Our cars have have semi metalic break pads, incase of high end cars like porsche you have ceramic break pads which might get affected by small change in parameters.

BTW what car do you drive?

The faster you dissipate heat from the pads, the more effective they are. If you cannot dissipate heat fast enough, you will experience brake fade, where your brakes become practically useless until the pads are cooled down again. However, this paintaing business is not going to affect heat dissipation, it all depends on the circulation of air around the brakes.

In the case of Disc brakes, brake fade is more dependent on the dissipation of heat from the rotors rather than from the pads. [Is this so?]

You can't paint the rotors.

For Drum brakes, im sure that there are vents that facilitate the cooling.
if those are covered up then it could be a problem

Thanks for enlightening me but my question was, "every colour absorbs or dissipates heat at a different rate”. Seriously, since we are just covering the calipers with paint would that any way affect the breaking? (Sprucegoose posted the question i was trying tio ask :-), you are little faster dude)

No, like I said, it wouldn't affect the braking. You might look like a dork though . Btw, please don't color the drums, it looks really lame.

Can someone enlighten be as to how long does the paintwork last keeping in mind the serious heat stress that the paint will be exposed to? Also, where can such a job be done or is it just a DIY thing.

Brake calipers need to be painted with heat-resistant paint. Not the one that goes on the car body.

I've got mine painted with normal standox paint and there are no problems at all.

Question: If I have a red car then what color calipers would look best ? Red again or some other color. Kindly suggest.

Nope, these parts are not painted during the under boding coating (Anti-Rust Presumed).
Heat Dissipation has a LOT to do with braking efficiency.
I drive a SX4

Many components within the engine compartment are painted BLACK or are black, because the colour black gains & dissipates heat the fastest.

On the other hand the colour SILVER takes time to get heated but it also takes time to dissipate the heat hence it blocks the heat absorbed or being emitted from a source in the vicinity

You can't paint the brake pads either, my query was about the calipers housing the pads.

I must admit with those alloys and the blue callipers your car must be a killer. Btw can you help me with a place in bangalore where I can get my callipers painted and also the vitamin M that would be required ?

Golden(ish) yellow, don't know correct name of that hue but most bike calipers come in that color and it compliment black color of tyre well and look good.
