any ideas as to what the hell can cause this? 68, all drum, power booster and new master put in a few months back, done this once before, then was fine and it just did it last night causing me to tow it home,

If the new master/booster is not exactly like the old ones, your brake pushrod may be too long. If its too long there isn't enough free pedal. If there isn't enough free pedal, the master will not detent and release pressure.
How do I know this? I did the same thing last summer.
Disconnect both front and rear brakelines. The pressure should release. Then get a shorter pushrod and rebleed.
I had an old truck ('86 F150) that would do that. The shaft from the pedal was binding in the booster. I would have to pull the pedal back with my foot everytime I used the brake.
I'm not sure whether or not that is the same problem.

alright i have tomorrow and the following day off so i will have to pull it and see, as far as the pedal, when they locked up it would not move at all, was harder then anything. today it moves, but dont want to drive it with a chance it will do it again, the car is really a pita some times,

I'm with you on this! Did this many years ago putting a new master in my brother's 50 Merc.
Adjusted it so the pedal was high, very little free play. The phone rings late that nite. My brother is stuck the car won't move!
I learned very young...read the manual and set it up like it says! All that free play is to allow for heat expansion.
This is a self generating failure. As the brakes drag things heat up and it gets worse. When things cool you wonder what was the problem?
