Bruce,
If you already have the circlip out, the only thing keeping the piston
is corrosion and/or resistance from the cup. If tapping the cylinder on
a wooden block doesn't cause the thing to come out, you might (very
carefully) use compressed air to force it out. I say carefully, because
those things become quite lively missiles when they finally do let go.
You might try letting the thing soak in penetrating oil overnight before
going to extremes.
Regards,
Joe Curry
