you guys have me confused. mine is installed EXACTLY per hurst's instructions- after the block. one front brake line at the block is plugged, the other is teed to the front calipers and the line loc. i'll find out if it slips this weekend. it does push the fronts on the street, but i figured it's getting too much traction on dry pavement for the front brakes to hold. it never consciously occurred to me that the piston in the distribution block may be releasing some of the front line pressure. we'll see.
