I am going to try some more things in the morning. I didn't have much time today. Thanks a lot for the advice. The brakes, although I'm pressing them pretty hard, don't really have that much strength to them at all. Maybe, I just need to press harder. There definitely is a vacuum. I need to look up what is involved with this procedure. I have never dealt with brakes before. Do I just unbolt the master cylinder and the booster from the firewall, then, just replace with the new unit? Take care-
