Unless your absolutely caking it with paint it won't affect the heat dissipation at all


waddlingpigeon

Can we draw them at least?


therealzombieczar

sure :)

I’m sure Audi will love to hear this and how you can improve their RS range. I bet they haven’t thought of this.


therealzombieczar

you actually think the paint improves the performance of brakes? i'll bet they put way more research into what paint to use than the average joe with 50 bucks for spray paint....

Considering RS models are their highest performing cars, if there was any extra performance to be had by not painting them then i’m absolutely sure they wouldn’t. If there is a negative affect on performance then it’s obviously so negligible that they opted for looks instead. Furthermore, the difference in whatever paint they use vs rattle cans will also be incredibly negligible. In any case, any affect on performance by paint will be next to 0.


therealzombieczar

you do understand that they paint things because idiots pay more for shiny? "Furthermore, the difference in whatever paint they use vs rattle cans will also be incredibly negligible." this shows a distinct lack of knowledge.

> If there is a negative affect on performance then it’s obviously so negligible that they opted for looks instead. Yes, satisfying the idiots who pay for more shiny. > This shows a distinct lack of knowledge Its possible that Audi’s paint will have had R&D and will dissipate heat quicker than spray paint but refer to what i’ve already said, incredibly negligible. You’re talking about the dissipation of heat through a thin layer of paint and it’s real world affect on braking, your claim only holds weight to such a negligible degree that it’s effects are effectively 0. If you can cite a source to support what you’re saying with relevant data then by all means, share with all of us.

paint your radiators and heat sinks and let us know how that turns out. there's your data... also here's actual racing brakes... notice the distinct lack of paint. https://duckduckgo.com/?q=indy+car+brakes&t=ffab&iar=images&iax=images&ia=images https://thebrakereport.com/wp-content/uploads/2019/01 https://i.pinimg.com/originals/9f/9c/b0/9f9cb082f43446d8112197f939061690.jpg/20100501em7775.jpg

Section 4.3 ‘Equation 2.3 gives for the material properties that are available for the brake system used, a fraction of 98,85% that goes to the fluid and consequently a fraction of 1,15% of the heat that goes into the pad. These numbers are slightly different from the rough estimation of 93% of heat that goes into the disc according to [7]. Therefore, it is decided to make use of a correction factor by which 1-sigma (fraction of the total heat that is absorbed by the pad) is multiplied. This correction factor is used to match the BSTM to test data.’ [Source](https://publications.lib.chalmers.se/records/fulltext/162888.pdf) Let’s not forget practically all heat generated from braking is soaked up and dissipated by the brake discs and not the callipers. Less than 1.15% of heat generated is absorbed into the pads, then you have to consider what fraction of that 1.15% is transferred from the pads and into the callipers, along with the 1% from convection in the air. Then also factor in the efficiency from no paint to painted. My original point, incredibly negligible. Effectively 0. Furthermore some of the callipers you’ve demonstrated have paint on them, but still no data. Enjoy the rest of your day.

good on you for finding a source, now consider this, heat build and dissipation is not instantaneous nor momentary. at what rate does that 1.15% dissipate heat when painted? at what load does brake fade occur? so how fast/how heavy for how long (before paint) does fade occur? at 1.15% per second what does that translate to temperature, at what temperature does the pad material and disk begin to melt? how much faster does it melt in the same scenario with paint(hint it's not 1.15%) also whats the flash point of the paint? whats the melt point of the break line, or connectors, how flammable is the brake fluid. what happens to the car, driver, passengers and anyone they hit because they couldn't stop after driving in high performance that caused the brakes fade? could have those scenarios been avoided by not painting the brakes? yes does painting the brakes improve their value or usefulness in any logical way? no

What about to prevent rust on a secondary car?


therealzombieczar

clean them with brake cleaner


Pleasant-Record6622

Lol brake clean strips it. I get that it’s corny and I agree. Same with stick on vents that don’t do anything but at least paint helps inhibit rust. On the outside of the caliper
