Inspect brake drums.
Assembly (Fig. 23)
1.
IMPORTANT:Brake shoe lining surfaces must be
free of grease, oil, and other foreign matter.
IMPORTANT:Brake drum machining is not recom-
mended. Replace brake drums as a set to maintain
equal braking forces.
1. Apply a light film of lubricant to the following:
A. Ledges on which the brake shoes rest.
B. Pin surfaces on adjuster levers.
A. Clean drums with denatured alcohol. Check
braking surface diameter in at least three places. If
the diameter exceeds 6.320 inches (16.05 cm), re-
place both brake drums.
C. Anchor block surface that contacts shoe webs.
D. Both surfaces of belleville washers that are posi-
tioned between adjuster levers and backing plate.
B. Replace drums that are cracked, deeply grooved,
tapered, significantly out–of–round, scored, heat
spotted, or excessively rusted.

If removed, position lubricated belleville washer be-
tween lever adjuster and backing plate. Secure adjuster
to backing plate with washer and bolt. Torque bolt from

with two washer head screws. Torque screws from 110
to 120 in–lb (12.4 to 13.6 N–m).
If removed, secure wheel cylinder to backing plate
IMPORTANT:Replace brake shoes as a set (all four
shoes) to maintain equal braking forces.
A. Replace brake shoes if damaged or if lining is
worn to 1/16” (1.6 mm). Replace if lining is contami-
nated by oil, grease, or other fluids.

NOTE: Overheated springs lose their tension, and can
cause brake linings to wear out prematurely.
that each shoe is properly positioned at anchor block,
parking brake lever, wheel cylinder, and pin on adjuster
lever. Secure shoes to backing plate with shoe hold
down cups and springs.
B. Inspect brake shoe webbing, upper and lower
springs, and shoe hold down springs for overheat-
ing. Overheating is indicated by a slight blue color. In-
spect brake shoe webbing for deformation. Replace
parts as necessary.
CAUTION
C. Inspect hold down pins on adjuster levers for
bends, rust, and corrosion. Replace as necessary.
Be careful when installing springs to brake
shoes. The springs are under heavy load and
may cause personal injury.
3.
Inspect backing plate surfaces, which contact with
the brake shoes for grooves that may restrict shoe
movement. Replace plate if grooves can not be re-
moved by light sanding with emery cloth or other suit-
able abrasive. Replace plate if cracked, warped, or
excessively rusted.
6.
Secure brake shoes with upper and lower springs.

ers if deformation or excessive rust is found.
Inspect adjuster levers for deformation. Replace lev-
5.
Replace parking brake cables if frayed, stretched, or
kinked.
