Right? With all reason it should make the wheels spongy, not lock up. It's weird. But she's road worthy again that's all I care about now 😂

Found the problem,.it was indeed the brake booster. Put on the old brakes and they were still dragging after a few minutes. Pulled the master cylinder and checked the guide pins on the booster and those were fine and still cause the dragging.
Finally lucked into some place that sold a brake booster but it took 2 weeks to ship. It arrived and I got it installed yesterday and the dragging is gone now. So whatever it was was caused by the original booster.

I've seen that a couple of times but this was WAY back in the 1970's and early 80's. A slight leak in vacuum at the wrong spot would cause the pedal to slowly engage. Normally it will cause a loss of amplification. I traced one like that on a '59 or '60 Studebaker.
