Fig. 3 Brake Pedal Bumper Adjustment
Remove cotter and clevis pins attaching linkage rod to
brake pedal arm but maintain alignment of holes (Ref
Fig. 4 on page D-5). At this position, the push rod on
opposite arm of bellcrank should be against piston in
master cylinder but should not be applying any force. If
push rod is not against piston or is applying force,
loosen jam nut at free end of linkage rod and thread
clevis yoke forward or back as required. Tighten jam nut
to 65 - 75 in. lbs. (7 - 8 Nm) torque.

he drum must not
be turned to ‘true’ a worn
friction surface. Turning will make the drum too
thin causing drum and brake failure which
could cause severe injury or death.
Wear a dust mask and eye protection whenev-
er working on wheel brakes. Do not use pres-
surized air to blow dust from brake assemblies.
Remove cap to gain access to the castellated nut and
the cotter pin (Ref Fig. 5 on page D-6).
Remove the cotter pin and castellated nut as shown.
Do not apply the brake when removing the nut as the shoes
may not fully retract preventing removal of the brake drum.
Remove washer
Slide the brake drum from the axle shaft. If required, tap
the drum with a plastic faced hammer to loosen it from
the axle shaft or use drum puller (P/N 15947G1).
If shoes interfere with drum removal, rotate adjuster bolt
on back side of backing plate towards the axle to retract
shoes and remove brake drum.
Pay particular attention to the location of the inner brake drum
washer 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
foreign matter. Apply a small amount of anti-seize com-
pound to the axle spline. Install the inner brake drum
washer and slide the brake drum into place. Check to
insure the nose of drum hub is beyond the end of the
