42–06 Haldex Slack Adjuster
Lubrication
Automatic slack adjusters that have a grease fitting
must be lubricated periodically to ensure proper
brake operation.
WARNING
Failure to lubricate slack adjusters could lead to
dragging brakes or a brake failure, resulting in
property damage, personal injury, or death.
CAUTION
Do not use moly-disulfide-loaded grease or oil.
Both the life and reliability of the slack adjuster
will be reduced if this type of grease is used.
Lubricate the automatic slack adjuster at the grease
fitting. See
Fig. 10 . Use standard chassis lubricant
for Haldex slack adjusters.
42–07 Meritor Camshaft
Bracket Lubrication
IMPORTANT: Perform a brake inspection before
lubricating the camshaft bracket.
NOTE: If equipped with an extended-
maintenance Q Plus
™
brake system, the cam-
shaft bracket will not have a grease fitting.
These camshafts use a special NLGI Grade
synthetic polyurea grease and do not require
lubrication for 3 years or 500,000 miles (800
000 km), whichever comes first. The extended-
maintenance camshaft bushings are lubricated
during the brake reline service interval. For ser-
vice and lubrication instructions, see
Group 42
of the vehicle Workshop Manual.
For camshaft brackets with grease fittings, use an
NLGI Grade 1 or Grade 2 multipurpose chassis
grease. Lubricate the camshaft bushings through the
grease fitting on the camshaft bracket or the spider
until new grease flows from the inboard seal. See
Fig. 11 . Follow the steps below for proper greasing.
WARNING
If grease leaks out under the camhead, the cam-
shaft bracket grease seal is worn or damaged. See
Group 42 in the vehicle workshop manual for
