Only 2 possibilities.
One, a leak in the hydraulic system allowing fluid out and air in.
Two, a bad mastercylinder.
I vote for number one.
How far was the ride home?
Where the front wheels warm/hot?
If I had to guess from what you desribed. I would take a close look at the rear wheel cylinders. Out of sight and out of mind. Pull the drums and peel the rubber cap on the wheel cylinder back. If it is wet inside it leaks. Rebuild or replace. Do both sides even if you only find 1 side wet.
Good luck and let us know. :)
