thats very strange,  i assume then that the front connection on the b/b is just being used as a straight connector so you dont have one long pipe to make and fit.

Nooo... I don\'t know for certain, but I think Archbish is right. The top ports marked \'F\' on the Brake Bias will, I suspect, have a pilot drilling down into the rear brakes part of the B Bias. probably to push a spool valve down further as front brake pressure is sensed.
