Painting the Calipers
I got the calipers off and wanted to paint them to match the rest of my upgrade.
I took the banjo bolts that held the brake lines onto the calipers and screwed them back into the holes, this way brake fluid doesn't leak out and dirt/water doesn't get in while cleaning them.
I washed the calipers and brackets one at a time in the sink in my pantry, I wouldn't suggest doing them in a kitchen sink because of massive dirt
I used:
Simple green
Regular dish soap
Scrubbing brush
Old tooth brush
Scrubbing pad
220 grit sand paper
I sprayed the whole thing down with simple green and let it sit a minute then I started scrubbing. I used the tooth brush for hard to reach areas and the scrubbing pad+brush for the big areas. It took quite a while and lots of simple green to get the front calipers clean. After I was satisfied with how clean they were I used the 220 grit sand paper and hand sanded all the surfaces that I could get to easily. This should help the paint stick a little better. To finish I cleaned them off with the dish soap and dried them with a towel. I did the same for the rears but they weren't nearly as dirty.
Once they are all dried I used painters tape to cover the bleeder bolt, the banjo bolt, piston and rubber boot, and the rubber boots on the caliper brackets.
I used silver/aluminum 1200˚ paint on them. After they had dried enough to handle I brought them into the house and let them dry completely for a day.
