Item to be
Brake drums can become very hot during
vehicle operations. Place hand near drum
to check for excessive heat but do not
touch drum. Failure to comply may result
in injury to personnel.
Brake drum clearance must be checked
along centerline of brake shoe. Failure to
comply may result in damage to equipment.
Over time a ridge will form on the outer edge
of the brake shoes. This is normal and does
not affect brake shoe serviceability.

adjustment, defective, or inoperative brakes, or
rust on braking surfaces.
