Finally got around to that how to. This is devoted to those of us who don't like to see tape-and-spray jobs with paint on the pads and brake lines, and bare crevices that didn't get any paint at all. It does not take that much longer to do them right.
Jack up vehicle and put on jack stands.
Remove wheel of choice.
Compress brake piston to allow pad removal.
Remove retaining pins, pads and all hardware.
Disconnect brake line and plug or cap to stop fluid flow. (many ways to do this from vacuum line caps, wood plugs in the line or a piece of plastic bag stretched over the end and tied with a rubber band.)
Unbolt and remove caliper.
Pull caliper halves apart like so.
Plug the openings to the piston so keep out dirt water and paint.
Clean them up with a wire brush. Scrub them with hot soapy water to remove any grease or grime that might make the paint not adhere.
Rinse and dry. Apply primer. Don’t half-ass it and forget the primer.
Follow the labels directions for dry time and apply two to three coats of high temperature chemical resistant paint of your favorite color.
When it has thoroughly dried, reassemble the caliper halves, and remove the plugs you put in the piston.
Now all you have to do is reinstall and bleed. There are many ways to bleed brakes, but this is what I did. With the brake line hole facing up fill the piston with clean brake fluid. Check the reservoir on the car to make sure it is full. Bolt the caliper back on the car holding your finger over the hole in the piston so the brake fluid does not all drain out. Then as quickly as you can remove the plug or cover on the brake line and screw it onto the piston. Then open the bleeder valve. The fluid should begin draining. Gently tap the piston with a soft mallet till no air bubbles are coming out in the fluid and then tighten the valve. Install the pads and hardware and pump up the brakes. Crack the bleeder valve again and let it gravity bleed a little while checking for bubbles. There should be none.
Note that this post is supposed to be about painting calipers, not the definitive how to on bleeding brakes. That can be found elsewhere.
You should have something that looks like this.
Have fun. |

How'd you neutralize the surface rust that wouldn't come off with a good wire-wheeling?

When I did mine I decided the timing was good for a caliper rebuild. At about 18.00 bucks a kit, it was cheap insurance and the crap that builds up in the calipers over the years will amaze you.
