Screw it (literally). The rear pistons typically must be screwed
clockwise while pushing. It can take a number of turns before you see
them start to move. If there are two indentations across a diameter of
the piston face, this is probably your setup. There is a nifty tool
that looks like a cube w/ pins sticking out that will help immensely.
Cost ranges from <$10 to $20, depending on brand and where you buy; many
auto parts stores carry this. It fits on a 3/8 drive; best way I've
found is to put a 1/4 x 3/8 adapter on it, and run it w/ a 1/4-drive
nutdriver handle. I filed two of the pins _slightly_ to get a perfect
