As I said before thanks to everyone for all the information. It always helps to know more about what you're working on. When I was speaking of rebuilding the cylinders I meant the Brake master cylinder and the inching pedal master cylinder. I adjusted the clevis to what I believe to be the point indicated by a couple of you in this thread. After putting everything back together I have functional brakes, for now. They worked well the last time too, until they built up enough pressure to lock up. I will keep you posted on their functionality and request further guidance in the event that they lock up again.
