if the brake responds poorly, verify that the all link-
age is tight and that the belts are tight and free of
oil or grease. replace the brake shoe set if the
lining thickness is
3 ⁄
16
" or less. When inspecting
for amount of brake wear measure from the fol-
lowing locations:
• if riveted linings are used, the measurement is
taken from the rivet heads to the lining surface
as viewed from the brake pad surface.
• if bonded linings are used, the measurement
is taken from the metal shoe surface to the
surface of the lining as viewed from the side
of the brake shoe.
When inspecting the drum, if the drum pulley is
bell-mouthd, cracked, or shows deep groves,
replace it. For minor scoring, the drum pulley can
be dressed with sandpaper or turned on a lathe.
