DIAGNOSIS
LINING INSPECTION
1. Raise and suitably support the vehicle.
2. Remove the wheel. Refer to Section 2E, Tires and
Wheels.
3. Release the parking brake.
4. Remove the drum. Refer to ” Drum” in this section.
5. Measure the lining thickness. The minimum lining
thickness is 0.5 mm (0.02 inch).
CAUTION : To avoid injury when servicing brake
parts, do not create dust by grinding or sanding the
brake linings or by cleaning the wheel brake parts
with a dry brush or with compressed air.
Important : Replace the shoe and lining assembly in axle
sets only.
6. Install the drum, if removed. Refer to ”One–Piece
Drum” or ”Two–Piece Drum” in this section.
7. Install the wheel, if removed. Refer to Section 2E,
Tires and Wheels.
8. Lower the vehicle.
DRUMS
Whenever brake drums are removed, they should be thor-
oughly cleaned and inspected to see if the drums are
cracked, scored, deeply grooved, or beyond the specified
out–of–round limit.
S A cracked drum is unsafe for further service and-
must be replaced. Do not attempt to weld a cracked
drum. Smooth out any slight scores.
S Heavy or extensive scoring will cause excessive
brake lining wear and may require refinishing the
drum braking surface.
S If the brake linings are slightly worn but are still re-
usable and the drum is grooved, polish the drum
with a fine emery cloth but do not refinish it. Elimi-
nating all grooves in the drum and smoothing the
ridges on the lining would remove too much metal
and lining. If left alone, the grooves and ridges
match, and satisfactory service can be obtained. If
the brake linings need to be replaced, refinish a
grooved drum. A grooved drum, used with a new

make it difficult, if not impossible, to obtain proper
brake performance.
