WARNING! If the brake fluid reservoir requires an
excessive amount of hydraulic fluid, the com-
plete system must be inspected for leaks and
repaired if necessary (consult your nearest
Peterbilt dealer). Failure to keep the brake sys-
tem in good repair may lead to loss of braking
and possibly cause serious personal injury.
Service Brake Component Inspection
Remove each wheel to inspect the brake components.
CAUTION: When replacing disc brake pads, be
sure to use the same lining material on both
axles. Mixing lining types can result in unbal-
anced braking, increased pad wear, or degraded
stopping performance. Consult your nearest
Peterbilt dealer.
Disc brake pads - Visually inspect all brake pad linings.
Brake pads should be replaced when the
remaining lining reaches 316 inch thickness or
less.
It is recommended that all disc brake pads be
replaced at the same time since this will main-
tain balanced braking. At a minimum, replace all
disc brake pads on one axle, both ends, at the
same time.
