Obyray,
My '64 had even a "better" issue with the brakes. The day I drove it home, the brakes locked up completely. I pulled the master cylinder off and discovered that the booster (push) rod to the piston in the master cylinder wasn't adjusted correctly. It has an adjustable rod end; the booster rod and master cylinder piston aren't connected.)If the booster rod isn't set correctly, the booster won't allow the rod to pull back from the master cylinder, thereby maintaining pressure to the wheel cylinders and making the brakes drag and not letting the brake pedal return fully, making you think that there is binding in the system.
There is no return spring externally for the system; it's in the master cylinder on the piston just for the the piston.
The shop manual has the correct min and max extension of the booster push rod from the booster housing (also, a diagram of a gauge that can be made and used for approximate adjustment). :cool:
