Sorry if I misunderstand. Is it your intention to remove the calipers to facilitate a brake bleed? Normally the calipers are left on. Check this page out for brake beeding tips.

Stuck pins are not desireable though. I would consider removing the calipers and driving out the pins with a hammer and a steel rod so that you can clean them off. If they stick they don't release the pressure off the calipers and pads properly leading to either premature brake wear or even brake failure. Maybe you could obtain a used set from a wreckers real cheap.
