Could be sticky pistons or the slides. When you pull it apart, make sure the pin is well lubricated with high temp silicone grease made for this purpose. If its the piston, rebuild the caliper. The GM rebuild kit is very complete and its a fairly easy job.

If the pin has been sticky for a while now there's a good chance the piston is sticky as well. The calipers are so cheap, I'd replace it rather than risking a bad rebuild. Change the front 2 rotors too because they'll be warpped

When I replace the pads, I always remove most of the fluid in the master cylinder resoviour and push both pistons all the way into the calipers prior to removing them. Then I pump them back out. I do this a few times. If you have a stuck piston, that is where you will see it. i bet you that the slider pins are frozen or excessively stiff. Pull the pins out, and clean the pins and the wells that theu slide in with solvent. (Brake Parts Cleaner) Examine the pin boots and make sure that theu are not torn or defective. Grease the pins with the "SPECIAL" high temp silicone grease made for this purpose!!!
Once you do all of this, your problems should be resolved.

NOOOOOOOOOOOOOOOO!!!! 
DO NOT REMOVE THE PISTONS!!! Unless there is a problem with the pistons, just cycle them before you take them apart! Just pry the brake pads all the way in and pump them back out.
Yep, brake parts cleaner is the ShIZs! It is safe on the paint, cleans well and evaporates easily!

Do not remove the pistons, I would clean / lube the slides, and push the pistons in, making sure the caliper is free and the pads are free from causing the friction material to "drag" when the brakes are not applied is one cause, another could be a warped rotor, if you take the pads off the car and look at them is the friction material wedge shaped like holding one pad is one side worn more then the other? this can be a sign of one slide sticking more or a warped rotor.
just some ideas...
