Where the rods go in should be a snap ring in a groove. Using snap ring pliers, remove the rings.
To get the pistons out, cover put a piece of cloth on your work bench (or a piece of lumber) and begin somewhat forcefully smacking the master onto the cloth flat on the opening side. once they unstick, they should come out without too much difficulty.
inspect inside the bores for rust or debris rings. if you see anything like that, use a scotchbrite pad and some type of solvent to clean it out.
If the seals on the pistons look ok, (no tears or really chafed edges) they should be able to be reused.
Next to where the seals are on the pistons is a metal portion that is just a bit undersize to the bore. smooth that off with the scotchbrite--if there's any burrs etc on those, sand or file them off.
Use carb cleaner or brake cleaner to flush everything clean, blast it all out with compressed air.
reassemble, fill & bleed.
