The brakes on these trucks should be recalled!!! I just got mine back from getting axle seals put in, and i had the guy look at my brakes. he said he can't find anything wrong.
but yet they just suck. I tried all that I am willing to try (running out of cash).
best of luck with your 1/2 tun turd.

basically i changed all of the things i mentioned and now i press on the pedal and there is nothin no pressure i guess. when the truck is off they will pump up and get hard while i bleed it but as soon as i start the truck there is nothing the pedal goes all the way to the floor. i thought maybe it was just soft but i put it in reverse and i still couldnt stop i checked all the lines and no leakes. everything blead fine i have couple buddys who are techs and they are racking there brains

ok i guess my real question is what to do next if i have replaced the calipers and the master and the resevoirs in the drums and all pads. Do i replace the booster or do i have someone do a pressure test on the lines and if so could i test it myself or if you have something else in mind just let me know this is my only vehicle and i need to get to work so anything is appreciated thanks again

Don't replace the lines. You said the pedal pumps to a firm pedal when the truck is off. It's when you put a vacuum on it (engine running) that it drops to the floor. That doesn't have anything to do with the lines or anything at the wheels. And I doubt the proportioning valve. There's something with the power booster and the master cylinder. There's a hose that runs from the engine to the power booster. Remove it from the power booster and see what happens when the truck is running.
