right or left side of the vehicle. The adjusting pivot nuts can be distinguished by the number of lines machined around the body of the nut. Two
lines indicate a right-hand nut; one line indicates a left-hand nut. Another way to identify adjusters is to check thread pitch. The right side adjuster
has right-hand threads while the left side adjuster has left-hand threads. The adjuster will also increase in length when the lever is operated if
properly installed.
Installing Adjusting Assembly
11. Place the adjusting socket on the screw and install the assembly between the shoe ends with the adjusting screw nearest the secondary shoe.
12. Hook the cable hook into the hole in the adjusting lever from the outboard plate side. The adjusting levers are also stamped with an R or L to
indicate their installation on the right or left hand brake assembly.
13. Place the hooked end of the adjuster spring in the large hole in the primary shoe web. Connect the loop end of the spring to the adjuster lever hole.
Checking Adjustment Lever Operation
14. Pull the adjuster lever, cable and automatic adjuster spring down toward the rear to engage the pivot hook in the large hole in the secondary shoe
web.
15. Check the action of the adjuster by pulling cable toward secondary shoe, activating lever. Lever should snap in behind the next tooth of adjuster.
Release cable to return adjuster lever to original position and the adjuster should turn one notch.
If pulling the cable does not produce the action described, or if lever action is sluggish instead of positive and sharp, check the position of the lever
on the adjusting screw toothed wheel. The lever should contact the adjusting wheel one tooth above the center line of the adjusting screw. If the
contact point is below this center line, the lever will not lock on the teeth in the adjusting screw wheel, and the screw will not be turned as the lever
is actuated by the cable.
