8. Inspect brake drums for wear.
DO NOT operate the vehicle with the
brake drum worn or machined beyond
the discard dimension indicated by the
drum manufacturer. The brake system
could not operate correctly. Damage
to components, death or serious injury,
could result.
Replace the brake drum if it is out-of-round.
DO NOT turn or re-bore a brake drum
beyond manufacturers recommendations.
Doing so could decrease the strength and
capacity of the drum which, if not avoided,
could result in brake component damage.
a. Inspect the brake drums for cracks, severe heat checking,
heat spotting, scoring, pitting and distortion. Replace
drums as required.
b. Measure the inside diameter of the drum in several
locations with a drum caliper or internal micrometer
(Figure 29).
c. If brake drum is excessively worn or out of round
replace brake drum.
Failure to replace an out of round brake
drum could result in damage to brake
drum or other components.
