non-sticking pistons but it may not work on sticking ones.
Part the two halves of the caliper (four bolts). Place one half in a
vice with the inside of the caliper facing up. Remove the retaining ring
at the base of the dust boot then remove the dust boot. Re-position the
caliper in the vise so that the top of the piston is just about a 1/16
to 1/8 inch below the top surface of the vice jaws. Using two flat screw
drivers, on opposite sides of the piston, pry the piston up by placing
the end of the screw driver in the lip that retains the dust boot at the
top of the piston. Use equal pressure on both sides. With a little care,
you should be able to pry up the piston with little damage to the
retaining lip which can be filed smooth latter when the piston is out.
Once the piston moves up, re-postion the caliper lower in the vise and
begin the next round of prying. You may also want place some kind of
spacer under the shaft of the screw driver between the top of the vice
jaw to increase leverage.
This method does not work as well as the grease gun method but then
again you won't have a great gob of grease to clean up either.

This method does insure that you'll have to take it to Apple or someone else
for rebuilding though. You will not be able to properly reassemble the
calipers after you take them apart, so you might as well not mess with things
and take the calipers in for a rebuild to start with.
Alan, did the brakes work at all before you started working on them? What
was the problem you were trying to fix?
