painting brake rotor hat ok? anybody done it?

[VanIsleDSM]

not the flat part with the holes for the wheel studs, just the step from the rotor surface.. especially in the back, it's a big step, and it's starting to look a little ugly, never heard of doing this before, dont' see why it would cause a problem, just thought I'd check in before going ahead.

Well it may not cause a problem but the brake rotors can reach temperatures in excess of 2000 degrees. I don't think any paint will hold up to that.

EDIT: If you ever have a brake seize on you and you see smoke coming from the rotor. Do me a favor and don't touch it, you will leave skin on the rotor. Don't ask how i knew that, it was early in the morning and I was on my way to class.

Haha, yeah it does get a tad warm..
I don't think it'll intefere with the performance of the brakes, but make sure that you get paint that will bond to the surface good, make sure you have a nice clean/rust free surfice, and paint that has a high enough temperature rating. I've seen caliper paint rated at 1500+. I've never logged brake temps so i can't tell you. But I've come across higher temp. paint before, i'll try to find it again.

Logged brake temps... Lol. Why do you want to paint this anyway? If it's what I think you're talking about, you can't even see it with the wheel on.

 

[VanIsleDSM]

with my wheels you can, they're small light 5 spokes, it's very visible.

 

[blackbyrd]

Haha yeah, I mean I assume theres some sort of temperature sensor you can put on your brakes to read it? Dieseltech said 2000+.. Yeah it doesnt really seem that you could see it that well, but if the guy wants to do it what the hell.

Jet hot was what I found earlier, although primarily used on headers I doubt you'll get them to paint it for you, but it's rated up to 2,450 degrees, it does exsist..haha.

I wish I had a picture for you but I'll explain what I did for mine.
I use stock, painted, GSX wheels and they would clearly allow me to see, from almost any angle, rust all around the the edges of my rotors.
The rust was distinguishable and unwelcome. I was suffering at the time from having all 4 of my locking lugnuts stripped. Never trust a guy holding an airtool. Even if you're at Midas.
So I sprayed a bunch of Napa brand Generic black high-temp paint, same stuff I used for my valve cover, into a cup and used a dank old paintbrush to paint the rust black. Now the center and the vanes or outer edge of the rotors don't look so bad. It's a half assed job, but it looks way better.
The paint went on pretty thick and so far I have not suffered any mal effects. It hard to say if you would experience the same.

I'd only say to keep it clear from where the wheel will be mounting. I suspect it might make an awfully good bond under high heat.

 

[wret]

I spray mine once or twice a year with high temp aluminum.

 

[andymoraitis]

I also do mine a couple times per year with VHT Flameproof black (good up to 2000 degrees). Looks good and it seems to last for quite a while.

Picture of with and without for comparison?

 

[smokey8667]

that surface is visible on mine to and mine are silver now. worked great.

 

[VanIsleDSM]

excellent, thanks for the help, I'm gonna get some brake calliper paint and do the rotor hat sides/callipers/torque plates.

Painting rotor hats/vanes had always been done to resist rust. Painting thos areas not swept by the pad with high temp paint is ok esp. if you did not have zinc-coated rotors.

Some Corvette guys even go up a level and paint the holes of their cross-drilled rotors with high temp clearcoat. That's a little extreme (or OCD) for me but it does help in keeping your rotors looking new.

Just remember to buy zinc-coated rotors on your next brake job.

 

[VanIsleDSM]

when you say vanes, I assume you are reffering to the ribs between the disk surfaces that circulate the air? that would be worth painting aswell.

Painting the holes I would have to agree is ocd!! I just would never have the patience for that.
