Use air to blow the piston, stoping it with a block of wood across the
caliper fingers. Plan on bleeding the MC and lines to at least the front
calipers when they are out. You can plug the hose ends with carved tapered
sticks while playing with the calipers. To be complete, do the rears at the
same time. Wash the caliper internals with rubbing alcohol, isopropal or
methyl (save the ethyl for drinking). Polish the chrome plated piston OD
with 600 grit paper wetted with alcohol lightly, don't go thru the chrome!
I use a heavy Si oil as an assembly fluid, but brake fluid will do.

I didn't pretty up the UFO caliper exteriors either when rebuilding 6, 7 yrs
ago. One of my first new to me, used car jobs.
