The parking brake is integral to the rear calipers on this vehicle. So, you have to rotate the caliper piston, usually clockwise to get it to retract.
Actually I own a 2008 Saturn Aura. I just had that problem. I was replacing the rear pads and couldnt compress the caliper piston. I thought the caliper was siezed. What I did and found out was the correct way to compress a rear caliper with the EBrake attatched was to simply take a pair of adjustable plyers and put it around the rim of the caliper piston being careful not to pinch the rubber and slowly turn it clockwise until the piston is flush with the caliper itself. It slipped right on with no problem at all. It was the easiest thing. auto parts stores also rent a set of tools for that type of caliper. FYI calipers with the e brake attached cannot be compressed with a c clamp or plyers no matter how hard you try. The piston must be rotated to compress. Hope this helps !
I not sure if it's the same brake set up but if it's a e-brake built into the caliper, on my Saturn aura 2007 I had to put the c clamp on the bolt on back of caliper and it directly on the caliper and it rotated back into housing as it pushed. I tried it with the brake pad between it and the caliper much like you typically do and it would not budge. Do it without and it will rotate back in worked like a dream for me. Yes Ideally you should buy the tool but i used just the c clamp and took off the cap to brake fluid and it worked like a dream. No tool needed and no damage done to it, you can't go wrong in my opinion. But ps I just did this about 20 minutes ago and it worked on both sides.
Worked perfectly for me too. I made sure the c-clamp had a rotating base. It was tough to turn at first, but after that, the caliper rotated right back into place.
