Passenger brake won't bleed seems as if there is a blocage in the line

Decided to replace brake pads, they had 1/4 life, had to replace the caliper and the flexible hose. Tried to bleed the line, no fluid coming from the nipple the wheel would lock up solid and would take a minute or so to relieve the pressure. Replaced the brake line (did a pressure in a 5 gallon pail of water) next replace the Kelsey-Hays controller. Very little has changed.
What am I missing.
It has become an urgent matter for me, I live in a small town. My wallet was stolen and I need to get into the city to get a new debit card, other wise I would pay the standard rate of $40.00.
