15 - 12 BRAKES
3. Check linings for wear and loose rivets. Inspect linings for
metal or foreign particles that may be imbedded in the
surface and remove any that are found.
Shoe and lining assemblies having linings soaked with
lubricate or Hydraulic brake fluid should be replaced.
They cannot satisfactorily be cleaned.
NOTE: Use wheel cylinder clamp KMO-145 if brake
shoes are to be removed. This clamp prevents the piston
being forced out of the wheel cylinder either from the
natural back pressure in the hydraulic system (combined
with the spring pressure between the cups), or by an
accidental movement of the brake pedal. Piston ejection
would cause loss of fluid and allow air to enter the hydraulic
system, necessitating bleeding the system.
4. Inspect each drum braking surface and rebore the drum if
necessary.
Remove only sufficient metal to provide a smooth and
true surface. If excess material is removed, the drum may
be weakened to the extent that erratic braking and lining
wear may result.
5. Disconnect hand brake cables at the toggle (35) Figure 1.
6. Thoroughly clean shoes and brake plates with a steel wire
brush. All brake frictional points should be thoroughly
cleaned after which a thin coat of lubriplate should b e
applied at these points.
7. Clean the exposed portion of all hand brake cables and
then pull the cables through conduit from the wheel end
to expose that part of cable that is sheathed by the conduit.
Clean this portion of the cable and lubricate freely
with viscous chassis grease. Figure 10.
8. Push cable into conduit and after the shoes have been
reinstalled, connect the cable to the shoe cable lever (5),
Figure 1, leaving
the adjustable yoke ends (25) of cables disconnected from
toggle (35).
9. To connect brake cable to shoe operating lever move
cable return spring (12) away from cable end and place
end into groove at the end of operating lever.
After the cable is in place allow the cable return spring
to return against the lever to hold the cable in place.
10. Inspect backing plates for looseness and tighten if necessary.
NOTE: When newly lined shoes are installed it will be
necessary to back off on the adjusting screw to provide
clearance for drum installation. After rear shoes are in
place, attach the cable end to the rear brake lever, but do
not connect front end of cable.
11. Lubricate the front wheel bearings by applying a milled
sodium soap base lubricant to the bearings and races
only (3 ounces is sufficient).
Excessive looseness at front or rear wheel bearings
should be corrected.
12. Before installing the front wheel hub and drum, remove
any excess grease from inside the hub to prevent grease
leakage onto the brake assembly.
13. Check the level of lubricant in the rear axle housing. This
should not be above the lower edge of the filler plug hole.
Too high a level will cause lubricant leaks at the rear
wheel oil seals.
14. After installing hubs and drums, insert a pry between the
linings of the secondary shoe and the drum (through
drum feeler gauge hole) and move the shoe assembly
until the primary shoe is against the opposite side of the
drum, Figure 13. The primary shoe can be pried against
the drum by inserting the .015" feeler gauge between the
adjusting screw end of secondary
