Powder Coated my Brake Calipers
This weekend I decided to try out my new harbor freight sand blaster and powder coating machines. The results are impressive!
Took me about 8 hours to do all four wheels.

I have powdercoated calipers on all my cars. T/A & vette are PC from mfg (Baer brakes), my BMW & wife's Pontiac done @ local shop - never had a problem with any of them - heat related or otherwise...

Uh, that's not true. Thermosetting Polyester TGIC paint is good for at least 250-300 degrees. Your calipers should never get that hot, rotors yes, but not calipers. You'll start to boil your brake fluid at that temp.

What is a joke? Go look up brake/caliper temperatures vs. powdercoating heat tolerance/heat retetention. I'm not suggestion OP's brakes are going to explode, but if he is going to track his car - or used a coating with a low heat tolerance - it *could* be an issue.
The powdercoating material itself ranges greatly in heat tolerance. From thepowdercoater.com: "Most powders are manufacturer rated at 250-300 degree operating temperatures." In comparison, G2 Caliper paint is rated at 980 degrees tolerance. "It is not uncommon to have caliper temperatures exceed 200° F" - Michael Romano, Mechanical Engineer (Source) Not stating it is a problem for all people, but rather it could be a problem for some people. |

I suppose that if I were track the car hard the calipers could reach into the upper threshold of the powder coating temp, but its HIGHYLY unlikely unless I was driving with my foot on the break and probably warping my rotors. I would think that for my calipers to reach 300 degrees, my rotors would be glowing...

Glowing rotors are awesome...assuming that your brake system is designed to handle such extreme conditions. |

What did you bake it in? That's always been the hangup for me, wife would take a dim view of using the oven and I really don't think I want to install one in the garage just for powder coating.

Toaster oven. Target had a huge one on sale for $40 a few weeks ago.

Lol. That's fantastic, albeit somewhat limiting on the dimensional requirements of the items you're coating.

You see glowing rotors on stock brakes frequently at the track

Breaking down the calipers is actually very easy. By the time I got to the third wheel, I could have the entire assembly removed from the car and completely broken down in 10-15 minutes. Rebuilding was as simple as doing everything in reverse. Just be prepared to get dirty. As for the tape I used, home depot/lowes sells metal based tape for HVAC ducts. It's basically aluminum foil with adhesive on one side. It's pretty cheap and worked great.

The crappy cell phone pictures I posted don't do justice. The calipers looks incredible. Powdering coating is very tough, smooth, and glossy. Hosing the brakes/calipers off when washing the car actually cleans them now.
