I may be totally wrong here(so I'll apologize in advance if I am), but doesn't it depend on which side of the car he is on?Facing from the outside (where you'd be anyway), rotating the star wheel down tightens it. When you've tightened it as much as you can with a screwdriver, back it off (rotate up) 5 notches on the star wheel.
Canderson, thanks for the explanation. That makes it quite easy to remember the direction.As it happens, no. If you could set the RH and LH assemblies side by side you would discover that unlike a normal drum brake (where the star is offset to one end to contact the automatic adjusting pawl), the stars are centered and the adjusters are oriented the same way in both assemblies. In other words, as you would look down at the pair of assemblies, you would see the male threaded bit is on your right in both cases, for example.
So (and I hope this makes sense visually) once mounted, the adjusters point in opposite directions, and the action remains the same regardless of which side you're on.
