Brake Bias Valve leaking

'95 GT w/ABS: the Brake line junction under the master cylinder, I think it's the Brake Bias Valve.
Anyway, it leaks brake fluid at the front where a hex with a rubber seal is in the center is located.

What is this part called?

How do I fix it? Is it a remove & replace?

Weird thing, the brake pedal has been firm - so it's not sucking air. Brakes work fine - just loosing fluid.

Thanks!

should set you back about twenty dollars at a junk yard... its held in by a thirteen mm behind the strut iirc... then just use a line wrench or open ended on the lines... i dont remember the size on them sorry... you can always cut the lines with a wire cutter at the yard and mess with them at home... 3/16 line cuts like butter lol
