the rear brakes on this stratus and the right rear caliper will not release

I replace the rear brakes on this stratus and the right rear caliper will not release. There seems to be nothing wrong with the caliper itself. The pressure does not back off when you take your foot off the brake. I think it has anti-lock braking system. Any Ideas.

Is it only one side that will not release? How do you know that. Did you try squeezing the caliper back away from the pads?
1) Sounds like the rubber part of the line has collapsed,that line has a inner line that gets weak and when you press on the brake pedal it lets the fluid flow out to the caliper but when you let off and the fluid tries to return back the line collapses keeping pressure on caliper not letting it release...
2)And to prove this, get a c-clamp and push the piston back into the caliper. Remove the clamp and the piston should stay in the caliper. Start the car, push on the brake petal, turn the car off, and check to see if the piston stays in the out position. If so, replace the rubber hose. You will need to bleed the air out of the lines when that is done. Get some penetrating oil. I like Kroil, others on this list like PB Blaster. Spray the bleeders until you can loosen them. You will also need a friend to help with the bleeding.

Do you know the the stratus has screw in rear calipers and not push in calipers???
