Do you hear a hissing sound down by the pedal when you press it? Is brake fluid level ok?

No hissing sound and fluid level stays fine! I've been told that ther is an adjustment on the master cylinder

Spongy brake pedal with no hissing sound around pedal typically means failed brake master cylinder or low fluid. Your master cylinder might be shot. But for giggles inspect all brakes for leaks. A leak will also make a spongy pedal.

If the system has been open, the Ford ABS is noted for getting air in the RABS valve, you might try bleeding it there is a bleeder valve on the unit, unfortunately if you do find air in the RABS then you will still have air in the rest of the system.
