I just finished doing my calipers & rear brake drums with a popular brake
caliper paint system you get from the local parts store. I used a degreaser
cleaner to remove the any grease or contaminates first, then I used "prep sol"
to remove any silicon or dot 5 that may have gotten the calipers. To prevent
"fish eyes" you must have two clean rags. One is for the application of the
"prep sol", and the other to wipe off. That way you don't re-contaminate the
paint surface.
I used the gloss black finish and brush it on . The flow characteristics of
this finish is excellent, so that it looks likes like it has been "powder
coated".
I had enough material left over after applying with 2 coats on the drums & 3
coats on the calipers, that I was able to paint the tie rod links as well.

I will have to take exception with that statement. Acryli-clean and
similar
solvents are absolutely insufficient for removing silicon brake fluid. Ask
me how I know this!
No, don't, I'll volunteer it anyway. I have a fiberglass bonnet on Tiny
Tim
that was a victim of the DOT 5 spray from both the brake and clutch
circuits. When I went to convert the car from racer to street rod, I ran
into the problem. It appears that the extreme measures I am referring to
are no less than scrubbing the surface with AJAX or similar abrasive
cleanser.
Among the things that do not work are:
Alcohol, Acrili-Clean, Fin-L-Wash, Lacquer Thinner, turpentine... Need I go
on?

I agree, except the "extreme measures" can be as simple as wiping down with
a purpose-made solvent, like Acryli-Clean (PPG DX330) or Prepsol (DuPont).
Most solvents (like lacquer thinner) won't touch it, but Acryli-Clean takes
it right off.
It usually also picks up a lot more rust than you thought was left, too <G>
