Monthly Post-Trip Inspection
and Maintenance
Brake Component Inspection
Walk around the vehicle and inspect brake system
components for visible damage.
1.
Inspect all visible brake system components for
missing fasteners or signs of looseness, such as
rust tracks.
NOTICE
If the external breather tube or breather cap is
missing or incorrectly installed, road dirt and de-
bris can adversely affect the operation of the
brake chamber. Once inside of the chamber, dirt
and debris can cause the internal parts of the
chamber to deteriorate faster.
2.
Inspect the exterior surfaces of brake chambers
for damage. Make sure that breather holes are
open and free of debris.
NOTE: Do not route air brake lines on top of
anything likely to be stepped on.
3.
Inspect air brake lines for dents, swelling, kinks,
twisting, abrasion, and damage, especially near
moving parts.
4.
Inspect flex air lines for deterioration or signs of
abrasion.
5.
Inspect for cracked, worn, or oil-contaminated
brake linings and brake drums (or rotors).
