Installation Procedure
Caution: The procedures shown in this section are
applicable to vehicles originally equipped with Spicer
®
brand self adjusting brake adjusters only, and must not be
used for aftermarket retrofit. Specific retrofit instructions
are provided with retrofit kits.
Attach the Self Adjusting Brake Adjuster
WARNING: BLOCK WHEELS TO PREVENT VEHICLE
FROM ROLLING. CAGE SPRING BRAKES IF
INSTALLED.
NOTE: A properly working Automatic Slack Adjuster does not
require manual adjustment while in service. The manual adjuster
hex is intended for use during adjuster installation and brake
overhaul.
WARNING: Automatic slack adjusters should not be repeatedly
adjusted to correct excessive in service pushrod stroke, because
this condition indicates that a problem exists with the automatic
adjuster, with the installation of the adjuster or with related
foundation brake components which manual adjustment will not
correct.
1. Verify that the pushrod is fully retracted. Apply air to
release spring brake. If air is not available, spring brake
must be manually caged off.
2. Install anchor bracket loosely as shown. Do not tighten
anchor bracket fasteners. (See Figure 14.)
Note: Configuration of anchor bracket will vary depending on
axle. (See Axle Installations on pages 5, 6 and 7.)
3. Apply anti-seize type lubricant to the shaft splines. Install
the brake adjuster onto the camshaft with the adjusting hex
pointing away from the brake air chamber. Secure the
brake adjuster on the camshaft. Follow procedures in the
applicable Bendix Spicer Foundation Brake brake service manual
for checking and adjusting camshaft end play.
4. Rotate the 7/16" adjusting hex nut clockwise until the brake
adjuster arm hole lines up with the clevis hole.
(See Figure 15.)
5. Install clevis pin. Do not install the clevis cotter pin at this
time. It will be necessary to remove the clevis pin later to
check installation.
