The brake plunger does not move "past the front then to rear". There is a brake bias valve that controls pressure front to back. So I am thinking, if that valve is out of adjustment (badly), and the rear drums are sorta stuck, then you would have a hard pedal but almost no brakes. Solution >> pull the rear drums and/or verify the rear drum pistons are working. I bet there not (recall that from time to time, you have to do the backup and brake to 'set' the rear drums). But I also have to suspect there is something going on with the brake bias valve which would explain why your not getting any pressure to the front. This assumes the fronts are OK of course. ADD>> there is a special tool to set the front/back bias. But it would be cheaper just to have Ford do it. Hope you find a solution quickly.
