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. 5
. Use standard chassis lubricant for
Haldex slack adjusters.
