Pete,
I know you said they replaced the master cylinder, but with them
going to the floor and no sign of brake fluid on the ground (and a
mostly full MC) It pretty much has to be the master cylinder. I had
the same thing happen to my '69 when I was in college... it's truly
terrifying.
Can you get the brakes to 'pump up' if you pump on the pedal?

Need some advice on brakes.....Second time out last April, my
brakes failed on my '69 Chevelle. Had a repair shop that I have
delt with in the past and was very satisified with their work look
at and make the repairs. The master cylinder was replaced as well
as the rear shoes and rebuild the rear wheel cylinders . Checked
the front discs and they were fine . Brakes were working fine until
yesterday...brake pedal went to the floor and the brake lite came
on . Good thing this happened in my driveway and not on the road
like the last time the brakes failed . Put the car back in the
garage and checked the brake fluid level and it fine, about a 1/4"
fom the top. The brake job has less then 1000 miles on it. Any
ideas went could have happened ? Could it be the vacuum booster?
Thanks ,
