(7) Remove the screw fastening the proportioning
valve actuator rod bracket to the rear axle. Raise the
actuator lever to the full-upward position and hold it
there.
(8) With the aid of a helper, apply pressure to the
brake pedal until a pressure of 6895 kPa (1000 psi) is
obtained on the proportioning valve inlet gauge.
Then, based on the type of brake system the vehicle
is equipped with and the pressure specification
shown on the following table, compare the pressure
reading on the outlet gauge to the specification. If
outlet pressure at the proportioning valve is not
within specification when required inlet pressure is
obtained, replace the proportioning valve. (Refer to 5
- BRAKES/HYDRAULIC/MECHANICAL/PROPOR-
TIONING VALVE - REMOVAL)
CAUTION: Do not attempt to adjust the height sens-
ing proportioning valve. If found to be defective,
replace the valve.(9) Remove the pressure test fittings and pressure
gauges from the proportioning valve.
(10) Install the chassis brake lines in the correct
ports of the proportioning valve. Tighten all tube
nuts to 17 N´m (145 in. lbs.).
(11) If necessary, repeat the above steps on the
remaining side of the proportioning valve which con-
trol the other rear wheel brake.
(12) Attach the actuator lever and bracket to the
rear axle.
(13) Bleed rear brakes. (Refer to 5 - BRAKES -

(1) Using a brake pedal depressor, move and lock
the brake pedal to a position past its first 1 inch of
travel. This will prevent brake fluid from draining
out of the master cylinder when the brake tubes are
removed from the proportioning valve.
(2) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE).
CAUTION: Before removing the brake tubes from
the proportioning valve, the proportioning valve and
the brake tubes must be thoroughly cleaned. This is
required to prevent contamination from entering the
proportioning valve or the brake tubes.
(3) Remove the four brake tubes from the inlet and
outlet ports of the proportioning valve (Fig. 73).
(4) Remove the two bolts attaching the proportion-
ing valve and bracket to the vehicle (Fig. 73).
(5) Slide the bracket out from under rear track bar
bracket. Lower the valve down enough to pull its
actuator rod out of the axle bracket and remove the
proportioning valve from the vehicle.

nects the front parking brake cable to the left rear
and intermediate cable. The intermediate cable is
connected to the right rear cable using a parking
brake cable connector.
On vehicles equipped with rear drum brakes, the
rear service brakes also act as the vehicle's parking
brakes.
Vehicles equipped with rear disc brakes use a
small duo-servo brake assembly mounted to the each
rear disc brake caliper adapter as the parking brake.
The inside of the brake rotor (hat section of drum-in-
hat style brake rotor) is used as the parking brake
drum.
DESCRIPTION - EXPORT
The parking brake system on this vehicle features
a hand-operated parking brake lever. The lever is
located between the two front seats and requires a
special front cable.
OPERATION
The automatic-adjusting feature in the foot oper-
ated parking brake lever continuously applies mini-
mal tension to the parking brake cables when the
parking brake lever is in the released position to
keep them in adjustment at all times. Due to this
feature, the parking brake cables require no periodic
adjustment.
When the parking brake lever is applied, the
cables are pulled, thus applying the brake shoes
(rear drum brakes) or parking brake shoes (rear disc
brakes) at each rear wheel.
The brake shoes are mechanically operated by an
internal lever and strut connected to the rear park-
ing brake cables.
An equalizer bracket is used at the rear end of the
front parking brake cable to distribute tension
equally to each parking brake cable.
STANDARD PROCEDURE
STANDARD PROCEDURE - PARKING BRAKE
AUTOMATIC ADJUSTER TENSION RELEASE
The parking brake lever (pedal) mechanism used
in this vehicle is designed so that the automatic
adjuster is not required to be locked out when servic-
ing the parking brake lever (pedal) or the parking
brake cables.
This parking brake lever (pedal) mechanism is
designed so that the adjuster mechanism will rotate
only half a turn when the tension is released from
the parking brake cable. This eliminates the require-
ment to lock out the automatic adjuster when servic-
ing the parking brake lever (pedal) mechanism and
cables.Use the following procedure to release the tension
from the parking brake cables and the automatic
adjuster in the parking brake lever (pedal) mecha-
nism.
(1) Grasp the exposed section of the front parking
brake cable and pull rearward on it. While holding
the park brake in this position, install a pair of lock-
ing pliers on the front parking brake cable just rear-
ward of the second body outrigger bracket (Fig. 87).
(2) Remove the left rear and intermediate parking
brake cables from the parking brake cable equalizer
(Fig. 88).

(4) Remove the locking pliers from the front park-
ing brake cable. This will allow the adjuster in the
parking brake lever (pedal) mechanism to rotate
around to its stop. This will remove the tension from
the adjuster and front park brake cable (Refer to 5 -
BRAKES/PARKING BRAKE - STANDARD PROCE-
DURE).

AUTOMATIC ADJUSTER TENSION RESET
The parking brake lever (pedal) mechanism used
in this vehicle is designed so that the automatic
adjuster is not required to be locked out when servic-
ing the parking brake lever (pedal) or the parking
brake cables.
(1) Grasp the exposed section of the front parking
brake cable and pull rearward on it. While holding
the park brake in this position, install a pair of lock-
ing pliers on the front parking brake cable just rear-
ward of the second body outrigger bracket (Fig. 87).
(2) Install the equalizer on the front parking brake
cable.
(3) Install the left rear and intermediate park
brake cable in the correct location on the parking
brake cable equalizer (Fig. 88).
(4) Remove the locking pliers from the front park-
ing brake cable. This will allow the adjuster in the
park brake lever (pedal) mechanism to tension the
park brake cables.
(5) Apply and release the parking brake lever
(pedal) one time. This will seat the parking brake
cables and allow the auto adjuster in the parking
brake lever (pedal) mechanism to correctly tension
the parking brake cables.

ADJUSTMENTS
ADJUSTMENT - PARKING BRAKE CABLES
The park brake cables on this vehicle have an
automatic self adjuster built into the park brake
pedal mechanism. When the foot operated park brake
pedal is in its released (upward most) position, a
clock spring automatically adjusts the park brake
cables. The park brake cables are adjusted (ten-
sioned) just enough to remove all the slack from the
cables. The automatic adjuster system will not over
adjust the cables causing rear brake drag.
Due to the automatic adjust feature of the park
brake pedal, adjustment of the parking brake cables
on these vehicles relies on proper drum brake and
park brake shoe adjustment. (Refer to 5 - BRAKES/
HYDRAULIC/MECHANICAL/DRUM - ADJUST-
MENTS) and (Refer to 5 - BRAKES/PARKING
BRAKE/SHOES - ADJUSTMENTS).
When the park brake pedal is applied the self
adjuster is by-passed and the pedal operates nor-
mally to engage the park brakes.
When a service procedure needs to be performed on
the park brake pedal or the park brake cables, the
automatic self adjuster can be manually locked out
by the service technician.
