Brake System<br />
WARNING! Do not use any replacement part in<br />
the brake system unless it conforms exactly to<br />
original specifications. A nonconforming part in<br />
your vehicle's brake system could cause a malfunction<br />
resulting in an injury accident. Sizes<br />
and types are so related to one another that a<br />
seemingly unimportant change in one may<br />
result in a change in how well the brakes work<br />
for you on the road. If parts do not work together<br />
properly, you could lose control of your vehicle,<br />
which could cause a serious accident.<br />
WARNING! Do not work on the brake system<br />
without the parking brake set and wheels<br />
chocked securely. If the vehicle is not secured to<br />
prevent uncontrolled vehicle movement, it could<br />
roll and cause serious personal injury or damage<br />
to the vehicle.<br />
•Use wood blocks (4 in. X 4 in. or larger) against<br />
the front and rear surfaces of the tires. Be sure<br />
the vehicle cannot move.<br />
Lubrication<br />
Preventive Maintenance<br />
Cam-actuated brake components such as anchor pins and<br />
brake camshafts are subjected to high temperatures, and<br />
must be lubricated with nonmelting, water resistant brake<br />
grease meeting R–S Specification 0–616 (NLGI–Grade 1).<br />
• Lubricate according to Table 2, “Recommended Maintenance<br />
Intervals,” Page 120.<br />
WARNING! Do not apply too much lubricant to<br />
brake components—lubricate sparingly. Excessive<br />
amounts of lubricant could contaminate<br />
brake linings, which could reduce brake effectiveness<br />
and cause an accident.<br />
Brake and Slack Adjuster Lubrication<br />
According to the interval, pressure lubricate the slack<br />
adjuster and brake camshaft (bracket/tube). Two grease fittings<br />
are provided for both the slack adjuster and camshaft<br />
bracket/tube.<br />
• Use standard chassis lubricant (meeting No. 1 grade<br />
high temperature, water proof specifications).<br />
• Do not use moly-disulfide loaded grease or oil (they may<br />
shorten the service life of the slack adjuster).<br />
