On Bendix brakes, regardless of what vehicle they're on, the conventional procedure has always been to tighten the adjuster to get a "firm drag" (not locked up) and back the star wheel off one turn. That's usually 10 clicks. Once you start backing off, ignore any slight drag- - - -the bottom of the assembly "floats", and it's not uncommon to get a little scuffing noise even with the right adjustment. The brake shoes self-center every time the brakes are applied. On self-adjusting brakes with the fine tooth star wheel, adjust for a firm drag, release the one-way ratchet with a thin screwdriver, and back off 20 clicks.
