Hey guys - I should have clarified...that there piston and brake pad were totally seized up and rusted all to hell on the inside. Pumping the brake to get the piston to push it out was a no go, so I had to take it to the next step!
As long as you don't drill the housing to push the piston out

Somebody had a picture here what the PO did to a brake caliper. Drilled a hole, pushed the piston out and plugged the hole again.
For stuck piston off the bike or when the MC is not strong enough there is either grease gun or compressed air. Compressed air - from what I understand, I always use grease gun - is more fun, since the piston shoots out very fast, but grease gun is the preferred method.
