144 Maintenance
Brake Safety Information
The brake system is a critical vehicle
safety system. For your safety and for
those around you, follow the recom-
mended preventive maintenance checks.
If any problems occur, have them inves-
tigated immediately by an authorized
service facility. Failure to properly main-
tain the brake system can result in
compromised brake efficiency and may
lead to loss of control of the vehicle re-
sulting in severe personal injury or death.
Do not use replacement parts anywhere
in the brake system unless it conforms
exactly to original specifications. A non-
conforming part in your vehicle’s brake
system could cause a malfunction, lead-
ing to loss of control of the vehicle
resulting in severe personal injury or
death.
Do not release the parking brake or at-
tempt to move the vehicle until brake air
pressure in both circuits is at least 100
psi (690 kPa). Failure to follow this pro-
cedure may lead to uncontrolled vehicle
movement and cause severe personal in-
jury or death.
Drain the air system tanks at the recom-
mended intervals. If condensation
accumulates, moisture can enter the
brake system air valves, causing corro-
sion or clogging. The safety of the brake
system could be compromised, leading
to an accident causing severe personal
injury or death.
Do not inspect or adjust parts or compo-
nents in the brake system without setting
the parking brake, placing the transmis-
sion in neutral and securely chocking the
wheels. If the vehicle is not secured to
prevent uncontrolled vehicle movement,
it could roll and cause severe personal
injury or death.
WARNING
Do not use penetrating oil, brake fluid or
wax-based oils in the air system. These
fluids may cause severe damage to air
system components.
