Front to Rear Brakeing Problem

I have a 1990 F-150 that I dont drive very often. ABout every two or three weeks. The last time I went to use it. The rear brake lines were rusted out and the pedal went to the floor. Before this it was working just fine. I repalced the brake lines and bleed them. Before I start the truck the pedal is firm. When I start it up it goes near the floor. When I drive it the pedal is soft and the rear brakes will grab and lockup with them doing most of the stopping power. I have bleed the front brakes endlessly and there is no air in the lines. I have bleed the master cylinder and the antilock module. No air is coming out anywhere. Any ideas what might be causing this???

Sounds like you still have air in the rears. Did you check the rear wheel cylinders for leaks?
Check to be sure and then try a gravity bleed and see if you get a firmer pedal.
