There is a tool for doing the rear calipers. Don't know what it's called (maybe caliper piston tool?), but it fits on a 3/8" drive ratchet and it fits into the four notches on the outer edges of the piston. I had to push and turn clockwise simultaineously. Be sure to spray lots of WD-40 on the rubber boot on the piston, or it can rip. Also, don't forget to take the cap off your master cylinder.
