Sounds like a faulty Master Cylinder.
If you continuously pump the brakes, and you get no pressure, yet there is plenty of fluid (and no brake fluid on the ground anywhere)....then this points to the master cylinder.
Have you checked the pads? Mine was doing the same thing, and when I went to get brake work done, I found out my pads were almost bare! Of course it may be some other defect, but I would definately get it checked out. Brakes or problems associated with them, can be costly if you hold off long enough.
