Check to ensure the nose of drum hub is beyond the
end of the axle splines. If not, remove drum and install
one additional inner brake drum washer (total of 2) to
obtain required spacing.
Do not back off nut to install cotter pin.
Install the remaining hardware and tighten the nut to 80-
90 ft. lbs. (108 - 122 Nm) torque. Continue to tighten
until a new cotter pin can be installed through the castel-
lated nut and the hole in the axle. Maximum torque is
140 ft. lbs. (190 Nm).
Wheel Brake Service
Wheel brake service consists of disassembly, cleaning,
inspection, lubrication and re-assembly of the wheel
brake. Worn or damaged components must be replaced.
Wheel brake service is required periodically as a pre-
ventive maintenance measure (see Periodic Service
Schedule in Section A). The wear rate of brake shoes
and required service intervals will vary based on usage,
terrain and other conditions. It is recommended that
wheel brake service be performed periodically on a
sample of vehicles within the service fleet to establish
the most efficient and effective service interval.
Remove the brake drum as described in ‘Brake Drum
Removal and Installation.
Wear eye protection and a mask when clean-
ing brake components. Do not use com-
pressed air to remove brake dust from brake
assembly
.
Do NOT use a commercial brake cleaner unless the
entire brake has been disassembled.
Remove any accumulated brake dust with a brush.
Remove the brake shoes.“Brake Shoe and Adjuster
Replacement” on Page M 12
Clean backing plate with a commercial brake cleaner.
Allow to dry completely.
It is important that the friction areas between the back-
ing plate and the brake shoes be lubricated. Be careful
not to allow lubricant to contact the braking portion of
the brake shoes or the friction surface of the brake
drum. Use only recommended lubricants.
Lubricate the backing plate friction points of the shoes
and moving anchor with Multi Purpose Grease (MPG)
lubricant (Ref. Fig. 12).
Fig. 12 Wheel Brake Lubrication Points
Install the actuator components, adjuster components
and brake shoes. “Brake Shoe and Adjuster Replacement”
on Page M 12 If the brake shoes and drum are not to be
replaced, sand the friction surfaces lightly with emery
cloth to remove any foreign material.
Be sure that the adjusting screw is screwed into the
star wheel nut until only 1 - 2 threads are exposed (Ref.
Fig. 15). If the brake shoes are replaced, replace the
three brake springs and the adjuster components.
Replace the springs one side at a time, using the other
side as a guide.
Install brake drum as described in ‘Brake Drum Removal
and Installation’.
Repeat on other side of vehicle.
Adjust the brake pedal free travel.
