WTF no brakes!
as you guys may or may not know I brought my truck to the body shop a few weeks ago, on the way there I hit the pedal and it turned into mush, no prob I figured, just air in the lines, I can bleed them when I get it back. Got it back, bled the brakes, still mushy, bled them again, still mush. I figured the master went to hell so I replaced that, still no brakes. I replaced both front calipers, still no front brakes (ended up rebuilding the whole front end....again) Now I just replaced the proportioning valve and I still got no front brakes. The rears lock up and the front dont do ****.
WTH is wrong with this thing!

RE: WTF no brakes!
when you bleed the fronts, have you got strong fluid pressure (squirt) at the calipers ?
just a thought. the proportioning valve somehow magically ? senses the pressures from the rear, and is supposed to balance the front vs rear. manually adjust the rear shoes up good and snug and see if that helps any.
another thought. if the rubber brake hoses on the front are old and soft, they can swell and absorb the pressure, robbing the calipers/wheel cyl of the pressure they need to operate. my old chevy did this.

plus one on the flex lines, mine went but they would lock up not absorb.
i had a squishy pedal for the longest time and i would bleed it and it would be hard for a few days then it would get squishy again. it turned out to be the line that goes in the frame over the gas tank, it was just rotten enough to let air in and fluid out but not enough to burst to let me no a line broke. pissed me off cuz it wasnt wet under the truck anywhere.

well, master cylender number 2 didnt fix it. checked the rubber lines going to the calipers and there is no swell going on at all, and when the fronts are bled there is strong fluid coming out of the bleeders. Im gonna jack the rear up and check the adjusters...again, but Im positive that they are already correct. Both rear wheel cylenders are working fine.
If you go down a blacktop road and lock the brakes up (just a quick smash on the pedal) it seems like they will alllock up, but than fade to nothing in the front and locked up in the rears
Makes me sick, i think im gonna buy a uni-mog
