Juddering on braking is normally warped discs.

Have you checked the hard/norm switch is actually connected, or that you even have the orginal adjustable shocks, lots have been relaced by now on these trucks.

The switch does very little in the real world anyway, working or not they won't make that difference to what you are describing, if you bounce the front of the truck are the shocks actually worn out?
