I would wonder if the lube used on the power piston assy was too heavy or the leather seal is damaged, or out of position. The recommended lube for the leather seal and vacuum canister is vacuum cylinder oil so a fairly light material. Is the condition of the canister interior smooth with no trace of any brake fluid that might have leaked in and gotten gummy. Anyl of those situations would cause a lot of drag on the piston the return spring might not be strong enough to overcome.
