There are three types of maintenance
intervals for general vehicle environments:
On-Highway, City and Severe Service. In
all applications, monitoring miles
(kilometers) and time and when the engine
is due for an oil change determine the
actual interval. When the engine oil change
is required before the truck lubrication
interval, perform the lubrication at the
same time in order to reduce your vehicle’s
time out of service.
Air Brake Adjustment
WARNING: Failure to maintain
proper air brake adjustment can result
in reduction or loss of braking ability.
A qualified service technician, keeping to
the instructions in the service manual,
should perform air brake inspection and
adjustment or repairs.
Cam Brakes - Automatic Slack
Adjusters
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.
Inspect standard air brakes equipped with
automatic slack adjusters for proper brake
adjustment as listed in the maintenance
schedule charts.
However, inspect the brakes more
frequently when subjecting them 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.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals.
