It may require downward pressure and spinning at the same time. I just did my rear brakes on an escort with rear disc brakes and this was the case.
You need to turn the piston clockwise and it will slowly retract as you turn.

Proper Torx bit or wrench for caliper C-Clamp to retract piston to get it off the disc
Clockwise to retract piston into caliper body
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.
