11. Measure the distance from the center of the large clevis
to the air chamber mounting face with the brake fully
released. This is dimension “X” in (Figure 8-43).
12. Using a pry bar, move the slack adjuster so that the
linings contact the drum. Measure the distance between
the same points as in step 11. This dimension is “Y” in
(Figure 8-43).
13. Subtract dimension “X” from dimension “Y”
(Figure 8-43). The difference should be 12.7 to 15.9 mm
(0.5 to 0.625 in). If the stroke falls within these limits, no
adjustment is required. If it falls outside these limits,
proceed to step 14 through step 16.
14. Disengage the pull pawl (Figure 8-44).
15. Turn the adjusting nut approximately 3.1 mm (0.1250 in)
turn in the direction required and re-measure the stroke.
Continue this process until the stroke is within limits
(Figure 8-44).
16. Release the pawl and uncage the spring brake, if
required.
Slack Adjuster Style #2
NOTE: If your slack adjuster is as pictured in (Figure 8-45)
Style #2, use the removal, installation and
adjustment procedures that follow.
REMOVAL
CAUTION
There are no serviceable parts inside the spring brake
chamber. Never attempt to disassemble the spring brake
chamber as serious personal injury could result from
accidental sudden release of the high energy spring.
CAUTION
See (Figure 8-43) and (Figure 8-44), Free Stroke
Measurement. Pull pawl must be disengaged before
rotating adjusting nut. Pawl teeth will be damaged if not
disengaged. Pry on the pull pawl at least 0.8 mm (0.0313
in) to disengage the teeth. When the pry bar is removed,
the pull pawl will re-engage immediately.
