BRAKE SHOE RELINING
Brake linings that are worn to with-
in 1/32 inch of any rivet or have
been contaminated with brake fluid,
grease or oil should
be
replaced.
Failure to replace worn linings will
result in a scored drum.
When it is
necessary to replace linings on
one
side, they must also be replaced on
the wheel on the opposite side of
the vehicle.
Inspect brake shoes for distortion,
cracks, or looseness. If this condi-
tion exists, the shoe must be dis-
carded.
Do not repair a defective
brake shoe.
