98 GT Brake Proportioning Valve Leak??

My valve seems to be leaking from the hole in the nut on the bottom of the contraption, which normally has a rubber boot over it. I took the rubber off and nut off and a spring and some fluid popped out (lets not read into that too much ehh?). The nut has a hole right through the middle of it, clear as day.

(I'm not sure but...) This proportioning valve seems to be the same kind as the older mustang models who are "gutting" the valve and plugging the hole with a solid plug... but I think mine is rotated sideways because my nut with the hole in it is on the bottom and not out the front.

What is this nut for?
Why is it leaking?
How do I fix it?

The only advice I can offer is to get a Haynes manual and read the master cylinder overhaul procedure. The Haynes manual is very good (well written, lots of pictures) and it costs about twenty bucks.
