Hmmm, if the problem isn't in the brakes/lines/cylinders...my memory is
that I had a vacuum leak at or near the deceleration valve and that
there is a vacuum brake assist on my '80.  Others might know where this
connection is as I had this trouble years ago.

...not sure if a failure here would give you the symptom you mention
though...likely that it would just make braking harder, requiring more
effort rather than letting the pedal go to the floor.

I'm more likely to think that you still have air in the system some where.
