On most cars, you can't just compress the disc piston on the rear caliper like you can with the front because of the mechanism associated with the parking brake. On Saabs (my experience is with the 9000), there is a hex head screw that you turn counter-clockwise with an Allen wrench to retract the piston. It usually works rather easily. On other cars I have worked on (Ford) the piston is compressed by turning the piston itself using a special tool with nibs that engage in notches in the piston. It works well enough, but isn't as easy as on a Saab. After installing the new pads, make sure that the caliper/piston/pads self adjust properly before you make any adjustments to the parking brake cables.
