DISASSEMBLY AND ASSEMBLY (Continued)

REAR DRUM BRAKE WHEEL CYLINDER
With brake drums removed, inspect the wheel cyl-
inder boots for evidence of a brake fluid leak. Visu-
ally check the boots for cuts, tears, or heat cracks. If
any of these conditions exist, the wheel cylinders
should be completely cleaned, inspected and new
parts installed.
If a wheel cylinder is leaking and the brake lining
material is saturated with brake fluid, the brake
shoes must be replaced.
BRAKE HOSE AND BRAKE LINES INSPECTION
Flexible rubber hose is used at both front brakes
and at the rear axle. Inspection of brake hoses
should be performed whenever the brake system is
serviced and every 7,500 miles or 12 months, which-
ever comes first (every engine oil change). Inspect
hydraulic brake hoses for surface cracking, scuffing,
or worn spots. If the fabric casing of the rubber hose
becomes exposed due to cracks or abrasions in the
rubber hose cover, the hose should be replaced imme-
diately. Eventual deterioration of the hose can take
place with possible burst failure. Faulty installation
can cause twisting, resulting in wheel, tire, or chassis
interference.
The steel brake tubing should be inspected period-
ically for evidence of physical damage or contact with
moving or hot components.
The flexible brake tube sections used on this vehi-
cle in the primary and secondary tubes from the
master cylinder to the ABS hydraulic control unit
connections and the chassis brake tubes between the
hydraulic control unit and the proportioning valve
must also be inspected. This flexible tubing must be
inspected for kinks, fraying and its contact with
other components of the vehicle or contact with the
body of the vehicle.
REAR WHEEL HUB AND BEARING ASSEMBLY
The rear hub and bearing assembly is designed for
the life of the vehicle and should require no mainte-
nance. The following procedure may be used for eval-
uation of bearing condition.
With wheel and brake drum removed, rotate
flanged outer ring of hub. Excessive roughness, lat-
eral play or resistance to rotation may indicate dirt
intrusion or bearing failure. If the rear wheel bear-
ings exhibit these conditions during inspection, the
hub and bearing assembly should be replaced.
Damaged bearing seals and resulting excessive
grease loss may also require bearing replacement.
Moderate grease loss from bearing is considered nor-
mal and should not require replacement of the hub
and bearing assembly.
ADJUSTMENTS
STOP LAMP SWITCH
(1) Remove stop lamp switch from its bracket by
rotating it approximately 30É in a counter-clockwise
direction.
(2) Disconnect wiring harness connector from stop
lamp switch.
(3) Hold stop lamp switch firmly in one hand.
Then using other hand, pull outward on the plunger
of the stop lamp switch until it has ratcheted out to
its fully extended position.
(4) Install the stop lamp switch into the bracket
using the following procedure. Depress the brake
pedal as far down as possible. Then while keeping
the brake pedal depressed, install the stop lamp
switch into the bracket by aligning index key on
switch with slot at top of square hole in mounting
bracket. When switch is fully installed in the square
hole of the bracket, rotate switch clockwise approxi-
mately 30É to lock the switch into the bracket.
CAUTION: Do not use excessive force when pulling
back on brake pedal to adjust the stop lamp switch.

group of the service manual for the installation pro-
cedure.
(13) Install wheel and tire.
(14) Tighten the wheel mounting nuts in the
proper sequence until all nuts are torqued to half the
specified torque. Then repeat the tightening sequence
to the full specified torque of 129 N´m (95 ft. lbs.).
(15) Lower vehicle.
(16) Apply and release the park brake pedal one
time. This will seat and correctly adjust the park
brake cables.
CAUTION: Before moving vehicle, pump brake
pedal several times to ensure the vehicle has a firm
enough pedal to stop the vehicle.
(17) Road test the vehicle to ensure proper func-
tion of the vehicle's brake system.
PARK BRAKE CABLE ADJUSTMENT
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. See Rear Brake Adjust-
ment and Park Brake Shoe Adjustment in the Ser-
vice Adjustments Section in this group of the service
manual.
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.
PROPORTIONING VALVE (HEIGHT SENSING)
Proportioning valve actuator adjustment will be
required if there is a complaint of premature rear
wheel lockup and the front and rear brake shoe lin-
ings checked OK during inspection, the height sens-
ing proportioning valve required replacement, or
there is a complaint of excessive pedal effort and the
vacuum booster and brake pedal checked OK. Make
sure the proportioning valve and the mounting
bracket are firmly attached to the vehicle. Then, pro-
ceed with the following procedure to perform the
adjustment of the actuator.(1) Raise vehicle. Vehicle is to be raised and sup-
ported on jackstands or with a frame contact type
hoist so the rear suspension of the vehicle is hanging
free. See hoisting in the Lubrication And Mainte-
nance section of this service manual.
(2) Remove rear wheels/tires.
(3) Using an appropriate jack, support the rear
axle prior to the removal of the track bar and shock
absorber bolts from the rear axle.
(4) Unbolt the track bar from the rear axle.
(5) Unbolt both shock absorbers from the rear
axle.
(6) Loosen (do not remove) both of the leaf spring
to front spring hanger pivot bolts.
NOTE: When lowering the rear axle be sure that the
leaf springs do not come in contact with the hoist
limiting the downward movement of the axle. If this
occurs an improper adjustment of the actuator may
result.
(7) Lower the rear axle so it is at its farthest point
of downward movement.
(8) Loosen the adjustment nut (Fig. 203) on the
actuator.
(9) Be sure the hooked end of the actuator is cor-
rectly (fully) seated in the clip on the proportioning
valve lever and that the clip is correctly positioned
on the lever of the proportioning valve.
(10) Pull the housing of the proportioning valve
actuator toward the spring hanger (Fig. 203) until
the lever on the proportioning valve bottoms on the
body of the proportioning valve.Hold the propor-
tioning valve actuator in this position while
tightening the adjustment nut (Fig. 203) to a
torque of 5 N´m (45 in. lbs.). Proportioning
valve adjustment is now complete.
(11) Install shock absorbers and track bar on rear
axle.Do not tighten the mounting bolts for any
of the loosened suspension components at this
time.
(12) Install the wheel/tires.

DESCRIPTION AND OPERATION
ANTILOCK BRAKES OPERATION DESCRIPTION
The purpose of an Antilock Brake System (ABS) is to
prevent wheel lock-up under braking conditions on virtu-
ally any type of road surface. Antilock Braking is desirable
because a vehicle which is stopped without locking the
wheels will retain directional stability and some steering
capability. This allows the driver to retain greater control
of the vehicle during braking.
This section of the service manual covers the description
and on car service for the ITT Teves Mark 20 ABS Brake
System and the ITT Teves Mark 20 ABS Brake System
with Traction Control. If other service is required on the
non ABS related components of the brake system, refer to
the appropriate section in this group of the service manual
for the specific service procedure required.
