Steve,
This happened on my car many years ago and it turned out to be a bad
"tipper valve" (also sometimes called a "tipping valve") in the master
cylinder. Apparently this valve allows fluid to flow back to the
master cylinder reservoir when you let off the brakes.
I'd say you either have a bad tipper valve (the fix would be a
new/rebuilt master cylinder) or perhaps bad front brake hoses, as
another lister already stated.
