Brake shoe lining wear
Check the
thickness
of the brake
linings,
and replace
both shoes as a set if
the
thickness at any point
is less
than the service limit.
If the thickness of the
brake
linings
is sufficient, check the
linings
for uneven wear,
and file or sand down
any high
spots. With a wire
brush,
remove
any foreign particles imbedded
in
the lining
surface.
Wash off any oil or
grease
with a
high
flash-
point solvent. Do not use one which will leave an oily
residue.
In
case t~e linings are damaged or the surface
cannot be restored by sanding and
cleaning,
the
shoes
must be
replaced.
