Manual brake push rod length?? Brake pedal is in the sky!

May not be it but I did notice when I was working on my 75 that the rod can get hung up inside the brake pedal and keep it up more than it should be. Found if you lift the pedal up then reach back to the rod and giggle it till it falls all the way in then the pedal goes back to normal.

May not be it but could be something to check on.
