Brake bleeding issue - 1970

[markedman90]

Car is equipped with Anti-Skid rears, new master, brake lines / hoses, wheel cylinders and calipers.
Front brake regulating valve opened with special tool as per manual, and I'm using a pressure bleeder @ 20psi.
Rears will bleed, but fronts will not.
Has anyone else experienced this, and if so, what would you think I'm doing wrong? 😕 😱

I know this is an old thread, you've probably figured out by now, but if not I had a Car I did brakes on years back that had same problem. Turns out I put the left caliper on right side, by doing that the bleeder was facing the wrong direction. I had three of the best mechanics come by, couldn't figure it out. Rotated calipers to correct side and bingo, solid pedal. Let me know what you found.
