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
Inspect the shoulder bolt for corrosion that could cause
binding. This bolt and both bushings must be replaced
with new ones if corrosion or wear is found.
Brake pedal installation is in the reverse order of disas-
sembly. Tighten the nut to 25 - 29 ft. lbs. (34 - 39 Nm)
torque and use a new cotter pin when installing the link-
age rod.
PARKING BRAKE
The rear brake includes a parking feature consisting of a
wheel brake lever and strut. The wheel brake lever is
applied by a cable attached to the parking brake lever
(hand or foot operated). The parking brake is used to
retain the vehicle when stationary. It may also be used as
an emergency brake in the event of hydraulic system fail-
ure.
The hand operated parking brake lever is located at the
right side of the driver in the console between the front
seats (Ref Fig. 9 on page D-12).
Lubrication
When lubricating parking brake,
be sure to use the recommended
dry spray lubricant. Commercial grease can attract
dirt and accelerate wear.
The hand operated parking brake lever requires periodic
lubrication with a dry graphite or molybdenum disulfide
lubricant. Raise the lever and spray into the underside to
access the pivot arm and ratchet mechanism of the park-
ing brake. See Section A - Periodic Service Schedule for
recommended lubrication schedule.
Adjustment
The parking brake adjustment is made at the clevis yoke
on the end of the parking brake lever cable located under
the front seats (Ref Fig. 9 on page D-12).
Loosen jam nut at clevis yoke.
Remove cotter and clevis pin attaching clevis yoke to
equalizer.
Rotate clevis yoke up or down the threaded end of cable
and reconnect to equalizer to check tension. Correct ten-
sion is when, at the sixth click of the hand operated park-
ing brake lever, vehicle movement is prevented while
under a load on a typical area slope. Readjust if nece-
sary.
Tighten jam nut firmly against clevis yoke to secure.
Cable Replacement
Cables should be replaced when they become inopera-
ble. Cable replacement consists of first removing the cot-
ter and clevis pins securing the cable to the equalizer
and wheel brake levers. Then remove the retaining rings
securing the cable to the frame and subframe. Install new
cable in reverse order of removal and adjust parking
brake system per instructions above.
