BRAKE SYSTEM PREVENTIVE MAINTENANCE
– 182 – Y53-6033
Regional Haul (R05/10)
WARNING! Do not use any replacement part
in the brake system unless it conforms
exactly to original specifications. A noncon-
forming part in your vehicle's brake system
could cause a malfunction resulting in an
accident causing death or personal injury.
Sizes and types are so related to one another
that a seemingly unimportant change in one
may result in a change in how well the brakes
work for you on the road. If parts do not work
together properly, you could lose control of
your vehicle, which could cause a serious
accident.
WARNING! Do not work on the brake system
without the parking brake set and wheels
chocked securely. If the vehicle is not secured
to prevent uncontrolled vehicle movement, it
could roll and cause death, serious personal
injury or damage to the vehicle.
• Use wood blocks (4 in. X 4 in. or larger)
against the front and rear surfaces of the
tires. Be sure the vehicle cannot move.
Lubrication
Cam-actuated brake components such as anchor pins
and brake camshafts are subjected to high temperatures,
and must be lubricated with nonmelting, water resistant
brake grease meeting R–S Specification 0–616 (NLGI–
Grade 1).
• Lubricate according to Table 1, “Recommended
Maintenance Intervals,” Page 150.
WARNING! Do not apply too much lubricant to
brake components—lubricate sparingly.
Excessive amounts of lubricant could con-
taminate brake linings, which could reduce
brake effectiveness and cause an accident
resulting in death or injury.
Brake and Slack Adjuster Lubrication
According to the interval, pressure lubricate the slack
adjuster and brake camshaft (bracket/tube). Two grease
fittings are provided for both the slack adjuster and cam-
shaft bracket/tube.
• Use standard chassis lubricant (meeting No. 1 grade
high temperature, water proof specifications).
