I had a problem like that once, a leaking seal in the master brake cylynder.
I don't think I lost any fluid, it would just leak past the plunger that was
supposed to make the pressure to apply to the brakes. I've noticed that some
of my present day cars have a little leak if I sit and play with them long enough,
but if you can consistently get the pedal to the floor I would have it fixed.
