you need to turn the caliper piston clockwise as it is being pushed in. There is a special tool but you can work it in with a c clamp, just make sure you don't tear the rubber boot. Also, make sure the nepressin area of the head of the caliper aligns with the raised point on the inner pad

The front brake caliper should retract with minimal effort with the aid of a c-clamp and an old brake pad. If it takes alot of pressure to make it retract I would replace the caliper. The rear brake caliper is a different story because it houses the e-brake also. The brake caliper piston must be rotated clockwise as you apply pressure to retract it. This requires a special tool that you can purchase from your local auto parts store. This tool is not expensive, it should be less than $20.
If it is the front brake use a "C" clamp to retract piston If it is the rear and the parking brake is used by this caliper piston is threaded and a special tool (not expensive) available at Sears or auto parts to "screw" piston into caliper body
Compressing the rear brake caliper piston on a 2008 Chrysler Town and Country requires a special tool that pushes in and turns the piston at the same time.
