The adjusting sleeve must bottom on the shoulder
inside of the plunger. If the bolt is threaded too far
into the sleeve, the bolt will bottom in the plunger
and the automatic adjuster will not function.
Insert adjusting sleeves (4), bolt
(3), and seals (2) into adjusting
plungers (1) already in right side

The adjusting pawl assembly (5) employs an integral
key which mates with a slot in the adjusting pawl
guide hole of the actuator housing. This assures
correct positioning of the pawl inside the plunger to
allow the brake to adjust automatically. The keyed
adjusting pawl (6), spring (8) and hollow capscrew
(7) are pre-assembled to facilitate reassembly of
these parts into the actuator housing. The capscrew
and pawl have hollow ends, and the spring has one
large diameter coil at each end which force-fits (pre-
snaps) into the open ends of the pawl and capscrew.
