The clearance between the piston and the bore is pretty tight, when you apply pressure to the piston its important to make sure the force applied is in-line with the bore of the cylinder in the caliper.
If you are applying force from a 'funny angle' the piston could jam against the cylinder wall and it would not move. Make sure the force is applied parallel to the bore of the cylinder.
Has the car had regular brake fluid changes? Since its been in your family since 1987 I'd guess it has and if so the piston should move with very little force - like maybe 10-20 pounds.
