Repair and Service Manual
Read all of Section B and this section before attempting any procedure. Pay particular attention to all Notes, Cautions and Warnings
Pay particular attention to the location of the
inner brake drum washer (6) inside the brake
drum, which may be on the axle shaft or attached to the rear of
the drum hub. This washer must be reinstalled when the brake
is reassembled.
To install the brake drum, clean the axle shaft and the
splines on the brake drum to remove dirt, grease and for-
eign matter. Apply a small amount of anti-seize com-
pound to the axle spline. Install the inner brake drum
washer (6) and slide the brake drum (5) into place.
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 castellated
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 preven-
tive maintenance measure (see Periodic Service Sched-
ule in Section A). The wear rate of brake shoes and
required service intervals will vary based on usage, ter-
rain 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 effi-
cient and effective service interval.
Remove the brake drum as described in ‘Brake Drum
Removal and Installation’.
Wear eye protection and
a mask when cleaning
brake components. Do
not use compressed air to remove brake dust from
brake assembly.
Do NOT use a commercial brake clean-
er unless the entire brake has been dis-
assembled.
Remove any accumulated brake dust with a brush.
Remove the brake shoes. See ‘Brake Shoe and Adjuster
Replacement’ on page K-17.
Clean backing plate with a commercial brake cleaner.
Allow to dry completely.
It is important that the friction areas
between the backing 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 sur-
face 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. 22 on page K-16).
Install the actuator components, adjuster components
and brake shoes. See ‘Brake Shoe and Adjuster Replace-
ment’ on page K-17. If the brake shoes and drum are not to
be replaced, sand the friction surfaces lightly with emery
cloth to remove any foreign material.
