rear caliper piston pressure

2002 trail boss 325
how freely should the pistons move inside the caliper? thinking my O rings may have swelled up or something causing too much pressure on the piston to allow it to move.

brakes are not working so i disassembled the rear caliper and had a %&^#$#$ of a time getting the pistons out. once out, they were not rusted/pitted or anything. cleaned and smoothed everything up, and the O rings looked good. when trying to put the pistons back in the caliper, i had to use a C clamp to press them in. brakes still dont work.

if i open the master brake cylinder by the hand brake and squeeze the hand brake, i can watch the fluid level rise/fall about 1/8"-1/4" or so. if i open the bleeder, fluid will squirt out.

the fluid reservoir by the foot brake does nothing when the foot pedal is pressed. i get 0 fluid out of the bleeder from the foot pedal, but i can hear a slosh/squishing noise from the caliper when the bleeder is open and pressing the foot brake.
