Greg, give me a call and let me know of your travel plans. As always, we'll buy you a good meal if you come to town. 931-378-2060.
I went to a few websites this morning and many of them say a bad GM booster will, amongst other things, cause the pedal to go to the floor. There is an obvious, loud suction sound coming from the (booster?) when brakes are applied.
I replaced my booster a couple of years ago. It was one of the nastiest jobs I've had to do on the bird, as the 4 nuts holding the bracket to the firewall were totally seized. Nothing would free them up so I had to cut the old bracket/booster off and install 4 new bolts through the firewall.
Good luck!
