there is a special tool that can be purchased at any auto parts store made specifically for compressing brake caliper pistons. I personally use a 4 inch c-clamp. works every time.
with a c clamp. put a block of wood or your old pad over the piston and tighten with clamp.
The piston in the rear caliper on the 2008 Grand Caravan is the "screw in" type. A special tool is required to do the job.

You don't remove the piston, you just compress it. Loosen the cap on the master cylinder and then compress the piston all the way in. You can then remove the old pad and install a new one.
with a tool that looks like a cube and you attach to a ratchet
Caliper front? Use a "C" Clamp Caliper rear? Threaded Need a special tool available at Sears or auto parts (Not expensive)
caliper piston does not retract with moderate C-clamp pressure - not willing to force it
I have used a large "C" clamp, to compress the caliper flush to the face.
Remove wheel, remove the two bolts in the calipers, pull up calipers, remove pads compress caliper piston with a c-clamp, be sure to have the brake fluid cap off the reservoir under the hood. - replace pads and reverse the order.
Replace the caliper and bleed the brake system.
If parking brake uses these calipers - they are threaded special tool (not expensive) is required, availlable at Sears or auto parts to thread piston fully into caliper body
There is a tool used to twist the piston back into the caliper I bought mine from Canadian Tire.
