Place a piece of wood, 1/2 or 3/4" across the opposite pad support ears such
that the pistons won't go flying, and but air pressure to the fluid input to
pop them out.  If you want to paint them for pretty, sand blast them and the
pad carriers before disassembling the calipers.

No, just sludged up, overhaul is long overdue.

If clean and lubed they should push in with light thumb pressure.  You can
reuse the seals and boots if they are not torn.
