Talking Anyone tried the Brake Caliper Paint Kit ?

I like the way Porsche does it, if I used red they would look like ceramic !
Anyhow, I think it would be neat with the Z4 sport package wheels.
I wonder who makes those wheels ?

I used Red Spray kit

Like the subject line says, the red spray kit worked really well.
I removed the wheel, then cleaned the beejeebers out of the calipers. I masked everything in sight, including the neighbour's car just in case spray travelled across the road.
5 or 6 coats of paint (it dried quickly) followed by many coats of clearcoat made the job perfect.
They've been painted for over a year now and still look great.
I clean with a sash brush and found a couple of benefits: it gets into all the little nooks and crannies of the wheel and gets through to the caliper also.
Would I do it again? Sure.

I got mine from the TireRack. It's been 2 years and I'm still happy with it. With the kit, after you mix it, you only have about an hour before it hardens, so you have to have everything ready... car up on blocks, all four wheels off, calipers cleaned really well. I didn't remove the calipers, just hand painted them carefully with a small brush.

You are correct, yellow is ceramic on Porsche.

i used VHT brake caliper spray paint. you have to cure it in the oven at 250F for 30min. after it is cured, it becomes solvent/chemical resistant and nice and glossy.

1. removed the calipers
2. cleaned like mad (brake cleaner, steam cleaner, dremel w/ stainless steel brush)
3. masked the piston and screw threads
4. hung them via coat hanger wires, sprayed 2-3 coats
5. cured in oven
6. install them with brass bushings, stainless steel lines, and chromed springs

Painted mine silver. It all depends on what color your car is.

Just to confirm... You can do all of this without removing the calipers??? That has been the main reason I haven't wanted to try it... I didn't want to mess with removing the calipers and rebleeding everything.

Not confirming the message you responded to, but in general, yes, you can do this without taking the calipers off. But to be honest, I don't think that would result in a professional looking job. That is a personal opinion of course.

If you decide to do this without removing the calipers, I would recommend using a non-spray paint kit. No matter how well you mask off the wheel well, it may only take one gust of wind to carry the spray paint to other body panels of your car. I would only do the spray kits if you remove the calipers and do the painting in an isolated area away from anything you don't want to get painted.

Removing the calipers and bleeding the brakes is not hard. The hardest part is cleaning the calipers correctly or risk painting over crusty brake dust and other contamination.

Though I like the look of painted calipers, I still have a hard time believing that hot painted brake calipers cool off as fast as bare-metal calipers. I mean, I wouldn't paint any heat-sink with a thick paint, and your calipers are basically heat-sinks when you're driving hard (the Dragon, Autocross, Track-day, etc.)

Yes, I see lots of factory-painted calipers from Porche and other factories, but I sort of assume that they were designed to shed heat with the paint already on them. Were factory-bare calipers designed to shed heat when covered in paint? I dunno.

If someone has some technical evidence either way on this, I'd love to see it. I actually have a set of blue caliper paint in the garage, now 4 years old, that I would love to use...

Greg,
I didn't take the calipers off but I did remove the wheels/tires and clips. Masking everything in sight took a while but the process worked well. The spray paint dried quickly so I was able to recoat fairly quickly.
The clearcoat spray I used also dried quickly so multiple coats happened fast.
I'm waiting for a sunny day for pictures but the multiday forcast looks gloomy.
Do you have sun in your area? Can I come live in your garage? Do you have beer in your fridge? I still like your TR6.
Enough questions, go and paint your calipers.
-John C.

You sir do very nice work! I like the finish of the paint, and I like the black color as well. I'm going to do the same to my E46.

Where did you get the chrome anti-rattle springs? Very nice touch!

How many cans of paint did you use? Which VHT product did you buy?

Thanks! Be happy to help you out if you need; just contact me whenever.

The chrome anti-rattle springs i bought from someone who got them chromed. You can buy new springs for $6/ea (so that they are clean) and get them chromed for $3-$5 a piece.

I bought 2 cans of VHT brake caliper paint in "gloss black". However, I didn't even finish the 1st can. I'll probably use the 2nd can on my E39.

With VHT caliper paint, you have to bake them at 200F for 30min to cure the paint. After that, it becomes solvent & chemical resistant. That way you don't have to worry about dripping brake fluid on it or anything. The cheapest place to buy VHT brake paint I found was Autozone.

Thanks for the follow-up and Autozone recommendation. Next time I swap pads for HPDE I'll paint the calipers.

And if I have some motorcycle parts at the chromer, well, maybe I'll throw those springs in the pile too.

I used VHT in yellow on our Roadster. I have a couple of the kits that Leather Z sells, but haven't used them yet.

I didn't oven cure the VHT. I just drove the car hard enough to heat up the calipers. As long as I clean them, they look great 3 years later.

Just did mine today. THe Pagid brake pads I recently put on were red. And I warmed up to the look. So painted the calipers red today. Didn't use a kit, just some red caliper paint that was rated high on amazon. Didn't do a complete disassemble, pulled the wheels, and the caliper (as if doing a brake job). Pulled the brake pads off, then remounted the caliper. That gave me enough room to properly mask the rotor and other components.

don't need to bake nuthin' in arizona. in summer we fry our eggs on the sidewalk.

i agree with sledgehammer, it depends on your car color. the green car looks good with red calipers. i'm considering orange for my blue car. just try to match the color values.

Space Gray '07 Z4 w/ Roundel Blue Calipers

I have been spraying my calipers for many years. Always use high heat engine paint. I found that Ford engine blue is a near perfect match to the blue in the BMW Roundel. One six buck can will easily do 4 coats. No mixing, no primer, no curing, very glossy finish, withstands wheel cleaner and high pressure car wash blasters. Have never experienced chipping or peeling. I'll send a pic when I clean my car.
