Brake Linkage

B
The brake pedal linkage is set at the factory. However, if
the master cylinder should have to be replaced, the link-
age may require adjustment.
The master cylinder is located under the driver seat and
is connected to the brake pedal by clevis yokes,
threaded rods and a bellcrank.

bumper in or out of mounting bracket as required and
tighten lock nut to 13 ft. lbs. (18 Nm) torque.
Remove cotter and clevis pins attaching linkage rod to
brake pedal arm but maintain alignment of holes (Ref.
Fig. 4). 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

The 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.
