How disc brakes work

(1990 Chevrolet 1500 Pickup)
in Pilot, VA on April 19, 2009
I understand stepping on brake pedal pushes fluid to apply pressure. What force returns pads to not applying pressure on rotors?

Actually, it is just the release of the pedal pressure combined with the rubber piston seals that very slightly pull back on the pads. They still actually touch the rotors, but they are not putting any real pressure on them.
