I thought about doing the brackets blue to match, I agree the black brackets do make the caliper appear smaller. But because of the difference in material in the bracket and caliper, I didn't think the colors would match or age the same. I dont have a write up per se with pictures, but I can give you a basic idea of how I did it.
Products used were all aerosol: Blue Duplicolor Break Paint- Eastwood (wasnt sure if my local store would have blue, and they didn't), VHT Black VHT high temp engine enamel- Advance Auto, Clear VHT high temp engine enamel- Advance Auto, Black Veloster Decal- GTAdecal, Painters tape and paper from Lowes. The only thing I didnt just have laying around was the Blue and Clear paint and the decal, my total cost was around $20 and time was around 2 hours.
1) Remove Wheels
2) Remove 2 Caliper bolts and remove
3) Slide paper over rotor and bracket, replace caliper. This allows you to make sure you paint the areas that are seen, along with giving a solid place to leave the caliper. Tape paper around wheel well to catch overspray
4) Paint Caliper- I did about three medium coats
5) After the Caliper has dried remove the caliper and tie it up out of the way and cover it with paper.
6) Use paper to cover the rotor, I used a note card to cover the break pad.
7) Paint Bracket- three medium coats again.
8) After paint has dried remove paper and reinstall caliper.
9) Install Decal
10) Tape up as much as possible
11) Paint clear over caliper and bracket to seal the decal
12) Remove paper and reinstall wheels
