In post #12 of this thread, Trog indicates:
"..has both an Edsel and a '56 Lincoln Premiere with Treadlevacs and we've not experienced the problems we've known on the Packards. Also he rarely needs to top off the reservoir. On all four of my '53-56s, I need to top the reservoit off several times a year. And"

AND trog mentions pedal return failure.

SO, has the vacuum can sucked enuf fluid from the MC over the years thus creating a hydraulic lock in the vacuum can. If it was just vacuum it would release normally. But if it becomes a full body of fluid then it would be very slow to release.
