Sand Blasting Calipers for repaint, Question.

I would not sand blast them just to eliminate any risk of sand staying behind. ESP if you have the four piston calipers since you cannot split them in half.
If you use a base coat make sure it is high temp primer.
I used a brass wire wheel on the end of a drill. It worked great. I would go that route.
You should rebuild them while you are at it. It is SUPER easy to do the front and the rebuild kit is rather cheap.

You could use a chemical paint stripper.... but again, it could be a problem with the rubber seals. Its also messy, and dangerous to the clothes and skin.
Personally, I use a plain old brass wire wheel, either in a drill or a 3600rpm bench polisher/grinder. I can control where the wire goes, it works quickly, and leaves a nice finish for paint to adhere to. Its not very messy, and provided you wear clothes, gloves, and eye protection, its very safe.
For paint, do NOT primer. Brakes get very hot, and will destory primer.
Instead, lay down 2-3 wet coats of VHT brake paint. Its $5/rattle can, it leaves a nice, high gloss finish, and the paint is very resistant to scratching off or being eaten by brake fluid/ brake cleaner. Also, the heat from the brakes will cure the paint, and actually improve its gloss.

OT, but a have a correction for Wankel7. You CAN split Mazda 4-piston calipers in half. They are bolted together and use 2 o-rings to seal the mating halves. I have done this with my own hands, so I know this is true for at least some of them. Now, there is little reason to split them, but I was rebuilding them, wanted to do a good job of cleaning and was curious ;-)

I don't wanna mess around and risk a front caliper leaking when i might need them the most.
