SAS brake question

[maroon ranger]

So I've swapped in a Dana 44 and a Ford 9" out of a 78 f150 into my 94 ranger. The brakes worked but the pedal wasn't solid. So I went with an 86 f150 master cylinder. Had to die grind the mounting holes and use one different flared fitting. Bench bled it and hooked it up. Now the pedal goes to the floor. I can pump the pedal and get good pressure and the pressure won't bleed off. But when I let off the pedal and push it again, it goes straight to the floor again. Vacuum bled them and got a couple bubbles out of the lines and let it sit for about 30 minutes while still holding vacuum pressure and tapped the lines all over and no more bubbles. No leaks either. Figured that would help but nothing. Pedal still goes to the floor. We plugged off the master cylinder, pedal was tight. Master cylinder is good, brakes are brand new front and rear. I'm at a loss. Need some help.

did you adjust the rod between the MC and vac booster?

No I didn't.

Figured out the problem! Had the calipers on the wrong sides. Swapped them around and bled them. Brakes are solid now!!!!!
