your master cylinder pedal is not allowing the cylinder piston to return to allow the brake fluid back into the resevoir-adjust the pedal free play-do you have a return spring to hold the pedal up so it does not put pressure on the master cylinder? you need one inch of free play with no weight on the pedal rod to master cylinder piston.

I had that happen on a 1946 sedan. The body mounts had settled enough that the pedal didn't come all the way back up and covered the return port. The vibration thus pumped up the brakes.Check that the pedal is returning. You perhaps can adjust it.

I have a stock 1949 Ford F-1 that has had no issues for the last 9 years since I put it on the road. About 3 weeks ago, I was driving it and noticed that the brake pedal got higher and higher until there was no play and noticed the brakes were dragging. I bled one of the bleeder screws and all 4 wheels released. I returned home, but again, every time I braked the pedal got higher and higher. I removed the master cylinder to check it and it looked like new inside. I ordered a kit anyway, installed it and bled the brakes only to have the same thing happen again. The pressure is so high in the system that with the truck sitting, the brake light switch is engaged and the brake lights will not go off unless I bleed one of the wheel cylinders. Before I change out any more parts, does anyone have an idea what might be going on? All the lines are stainless and were installed 9 years ago, all the wheel cylinders were new 9 years ago, as was the master cylinder. Thanks, SMB
