Air brake adjustment
WARNING:Failure to maintain proper air brake adjustment can
result in reduction or loss of braking ability.
Air brake inspection and adjustment or repairs should be performed by a
qualified service technician in accordance with the instructions in the
service manual.
Cam brakes - automatic slack adjusters
Inspect standard air brakes equipped with automatic slack adjusters for
proper brake adjustment as listed in the maintenance schedule charts.
However, more frequent inspection is required if your vehicle’s brakes
are subjected to heavy use or adverse operating conditions such as:
•Frequent brake applications while fully loaded.
•Operation on hilly or mountainous terrain.
•Frequent operation on dirt, gravel or mud.
Some aftermarket brake linings also require more frequent inspections.
WARNING:Do not manually adjust the automatic slack
adjusters to correct excessive push rod stroke as it may result in
reduced brake effectiveness and a vehicle crash. Excessive push rod
stroke indicates that a problem exists with the automatic adjuster, with
the installation of the adjuster, or with foundation brake components
that manual adjustment does not remedy. Seek service from a qualified
facility for excessive push rod stroke.
