the dreaded brake bleeding thread for a 71 C-10

[bmxbang]

alright guys here's the backstory. Brakes of course worked fine before I screwed with them. I overhauled the front suspension over a two month time span and left the front master cylinder dry because I took the brake calipers off it. now everything back together and low and behold my brakes suck. I have bleed them by hand with a vacuum pump and also with a pneumatic pump and no big difference. they have gotten slightly better but not by any means safe for the road. they will in fact stiffen up after I pump the pedal a few times so that makes me think I still have air in them. If I where to hop in the truck now the pedal feels very soft and will go all the way to the ground with out changing dramatically in pressure resistance. No leaks that I am aware of. ill take any advice. The front brakes are disk.
