If the parking brake is connected to these calipers they thread in clockwise special tool is available (not expensive) at Sears or auto parts If parking brake is not connected to these a "C" clamp should work to retract piston release the bleeder screw then either push them in or use a c-clamp to push them back in... this will waist a significant amount of brake fluid so make sure you have some handy I generally use a "C" clamp, but you can use whatever you have that will put pressure on the calipers to retract. The calipers move slowly and more pressure won't speed the process by much. If the calipers are moving, just keep even pressure on them.
