I had a time where the front brakes worked so well that it didnt allow enough pedal travel to push the fluid to the rear. what you had was a misadjusted master cylinder pushrod or bad mc. The situation you described should not happen.

For 71 the FSM says to replace the valve. 73 and later have an external plunger nub you can reset it with.
I would take it apart, clean it recenter it and reseal it.
I suppose you could pull the switch and try to recenter the shuttle thru that port.

with the valve been shifted over to the low psi side, with that corrected iirc there was something about slightly opening the high side making it now the low side & bumping the pedal to shift the valve back the other way to center it. Not sure how holding the "pin" valve open plays out with this procedure but others will clarify. I always thought the center valve was strickly an electrical on/off switch (to warn you of a leak on the "low" side) but did not shutoff flow so I learned something on this.

If nothing comes out of the M/C that is your issue. Kinda why I would start at the master. 1st, being you didn't install it, are you sure it is the proper unit?
I have mechanical Aptitude. I can screw up anything.

I believe to reset the valve the electrical switch must be removed.Open a bleeder on the brake circuit that works and have someone push the pedal down.If the shuffle valve is not jammed or or stuck that should re-center the valve.Install the switch and everything should bleed normally.

Never used their stuff.
I always grabbed one out of a Diplomat, just match the rear drum sizing.

Just thinking out loud & someone may clarify better if this ain't right. I would crack the line slightly (a bit downstream from the prop valve) on the side that was not opened/leaking & pump the pedal (fast/brief) (till the light goes out) to shift the valve back the other way to centered.
