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.

ABS BRAKES OPERATION AND VEHICLE
PERFORMANCE
This ABS System represents the current state-of-
the-art in vehicle braking systems and offers the
driver increased safety and control during braking.
This is accomplished by a sophisticated system of
electrical and hydraulic components. As a result,
there are a few performance characteristics that may
at first seem different but should be considered nor-
mal. These characteristics are discussed below.
NORMAL BRAKING SYSTEM FUNCTION
Under normal braking conditions, the ABS System
functions the same as a standard brake system with
a diagonally split master cylinder and conventional
vacuum assist.
ABS SYSTEM OPERATION
If a wheel locking tendency is detected during a
brake application, the brake system will enter the
ABS mode. During ABS braking, hydraulic pressure
in the four wheel circuits is modulated to prevent
any wheel from locking. Each wheel circuit is
designed with a set of electric solenoids to allow mod-
ulation, although for vehicle stability, both rear
wheel solenoids receive the same electrical signal.
During an ABS stop, the brakes hydraulic system
is still diagonally split. However, the brake system
pressure is further split into four control channels.
During antilock operation of the vehicle's brake sys-
tem the front wheels are controlled independently
and are on two separate control channels and the
rear wheels of the vehicle are controlled together.
The system can build and release pressure at each
wheel, depending on signals generated by the wheel
speed sensors (WSS) at each wheel and received at
the Controller Antilock Brake (CAB).
ABS operation is available at all vehicle speeds
above 3 to 5 mph. Wheel lockup may be perceived at
the very end of an ABS stop and is considered nor-
mal.
VEHICLE HANDLING PERFORMANCE DURING
ABS BRAKING
It is important to remember that an antilock brake
system does not shorten a vehicle's stopping distance
under all driving conditions, but does provide
improved control of the vehicle while stopping. Vehi-
cle stopping distance is still dependent on vehicle
speed, weight, tires, road surfaces and other factors.
Though ABS provides the driver with some steer-
ing control during hard braking, there are conditions
however, where the system does not provide any ben-
efit. In particular, hydroplaning is still possible when
the tires ride on a film of water. This results in the
vehicles tires leaving the road surface rendering the
vehicle virtually uncontrollable. In addition, extremesteering maneuvers at high speed or high speed cor-
nering beyond the limits of tire adhesion to the road
surface may cause vehicle skidding, independent of
vehicle braking. For this reason, the ABS system is
termed Antilock instead of Anti-Skid.
NOISE AND BRAKE PEDAL FEEL
During ABS braking, some brake pedal movement
may be felt. In addition, ABS braking will create
ticking, popping and/or groaning noises heard by the
driver. This is normal due to pressurized fluid being
transferred between the master cylinder and the
brakes. If ABS operation occurs during hard braking,
some pulsation may be felt in the vehicle body due to
fore and aft movement of the suspension as brake
pressures are modulated.
At the end of an ABS stop, ABS will be turned off
when the vehicle is slowed to a speed of 3±4 mph.
There may be a slight brake pedal drop anytime that
the ABS is deactivated, such as at the end of the stop
when the vehicle speed is less then 3 mph or during
an ABS stop where ABS is no longer required. These
conditions will exist when a vehicle is being stopped
on a road surface with patches of ice, loose gravel or
sand on it. Also stopping a vehicle on a bumpy road
surface will activate ABS because of the wheel hop
caused by the bumps.
TIRE NOISE AND MARKS
Although the ABS system prevents complete wheel
lock-up, some wheel slip is desired in order to
achieve optimum braking performance. Wheel slip is
defined as follows, 0 percent slip means the wheel is
rolling freely and 100 percent slip means the wheel is
fully locked. During brake pressure modulation,
wheel slip is allowed to reach up to 25 to30%. This
means that the wheel rolling velocity is 25 to 30%
less than that of a free rolling wheel at a given vehi-
cle speed. This slip may result in some tire chirping,
depending on the road surface. This sound should not
be interpreted as total wheel lock-up.
Complete wheel lock up normally leaves black tire
marks on dry pavement. The ABS System will not
leave dark black tire marks since the wheel never
reaches a fully locked condition. Tire marks may
however be noticeable as light patched marks.
START UP CYCLE
When the ignition is turned on, a popping sound
and a slight brake pedal movement may be noticed.
Additionally, when the vehicle is first driven off a
humming may be heard and/or felt by the driver at
approximately 20 to 40 kph (12 to 25 mph). The ABS
warning lamp will also be on for up to 5 seconds
after the ignition is turned on. All of these conditions
are a normal function of ABS as the system is per-
forming a diagnosis check.

DESCRIPTION AND OPERATION (Continued)

The front wheel speed sensor is attached to a boss
in the steering knuckle (Fig. 7). The front tone wheel
(Fig. 7) is part of the driveshafts outboard constant
velocity joint. The rear wheel speed sensor ismounted through the rear axle, rear brake support
plate and directly to the rear bearing (Fig. 8) (Fig. 9).
The rear tone wheel on a front wheel drive vehicle is
an integral part of the rear wheel hub/bearing
assembly. If damaged though, the rear tone wheel on
a front wheel drive vehicle can be replaced as a indi-
vidual component of the rear hub/bearing assembly.
Refer to Rear Tone Wheel in the Remove And Install
Section in this group of the service manual for the
required procedure. The wheel speed sensor air gap
is NOT adjustable.
The rear tone wheel on a all wheel drive vehicle, is
part of the outboard constant velocity joint on the
rear driveshaft (Fig. 9).
The four wheel speed sensors are all serviced indi-
vidually, but the front tone wheel on all vehicles and
the rear tone wheel on all wheel drive vehicles are
serviced as part of the front or rear driveshaft out-
board constant velocity joint (Fig. 7) and (Fig. 9).
Correct ABS system operation is dependent on
accurate wheel speed signals. The vehicle's wheels
and tires must all be the same size and type to gen-
erate accurate signals. Variations in wheel and tire
size can produce inaccurate wheel speed signals,
which can cause false ABS cycles to occur.
CONTROLLER ANTILOCK BRAKES (CAB)
The Controller Antilock Brakes (CAB) is a micro-
processor based device which monitors the ABS sys-
tem during normal braking and controls it when the
vehicle is in an ABS stop. The CAB is mounted to the
bottom of the HCU (Fig. 10). The CAB uses a 25 way
electrical connector on the vehicle wiring harness.
The power source for the CAB is through the ignition
switch in the Run or On position.THE (CAB) IS ON

ler, controls the yellow ABS warning lamp by directly
grounding the circuit.
HYDRAULIC CIRCUITS AND VALVE OPERATION
Through the following operation descriptions the
function of the various hydraulic control valves in the
ABS will be described. The fluid control valves men-
tioned below, control the flow of pressurized brake
fluid to the wheel brakes during the different modes
of ABS braking.
For explanation purposes, all wheel speed sensors
except the right front are sending the same wheel
speed information. The following diagrams show only
the right front wheel in a antilock braking condition.
NORMAL BRAKING HYDRAULIC CIRCUIT AND
SOLENOID VALVE FUNCTION
This condition is the normal operation of the vehi-
cles base brake hydraulic system. The hydraulic sys-
tem circuit diagram (Fig. 11) shows a situation where
no wheel spin or slip is occurring relative to the
speed of the vehicle. The driver is applying the brake
pedal to build pressure in the brake hydraulic system
to apply the brakes and stop the vehicle.
TEVES MARK 20 ABS CIRCUIT AND
SOLENOID VALVE FUNCTION
This hydraulic circuit diagram (Fig. 12) shows the
vehicle in the ABS braking mode. This hydraulic cir-
cuit (Fig. 12) shows a situation where one wheel is
slipping because the driver is attempting to stop the
vehicle at a faster rate than the surface the vehicle's
tires are on will allow. The normally open and nor-
mally closed valves modulate the brake hydraulic
pressure as required. The pump/motor is switched on
so that the brake fluid from the low pressure accu-
mulators is returned to the master cylinder circuits.
The brake fluid will then be routed to either the mas-
ter cylinder or the wheel brake depending on the
position of the normally open valve.
TEVES MARK 20 SECONDARY ABS CIRCUIT
AND SOLENOID VALVE FUNCTION
This hydraulic circuit diagram (Fig. 13) shows the
vehicle in the ABS braking mode. This hydraulic cir-
cuit (Fig. 13) shows a situation where one wheel is
slipping because the driver is attempting to stop the
vehicle at a faster rate than the surface the vehicle's
tires are on will allow. The normally open and nor-
mally closed valves modulate the brake hydraulic
pressure as required. The pump/motor is switched on
so that the brake fluid from the low pressure accu-

mulators is returned to the master cylinder circuits.
The brake fluid will then be routed to either the mas-
ter cylinder or the wheel brake depending on the
position of the normally open valve. A volume of 1.2
cc's of brake fluid is taken in by the lip seal saver
(Fig. 13) to protect the lip seals on the piston of the
master cylinder.

FUNCTION
This condition is the normal operation of the vehi-
cles base brake hydraulic system when the vehicle is
equipped with ABS and traction control. The hydrau-
lic system circuit diagram (Fig. 14) shows a situation
where no wheel spin or slip is occurring relative to
the speed of the vehicle. The driver is applying the
brake pedal to build pressure in the brake hydraulic
system to apply the brakes and stop the vehicle. The
hydraulic shuttle valve (Fig. 14) closes with every
brake pedal application so pressure is not created at
the inlet to the pump.

CIRCUIT ± SOLENOID AND SHUTTLE VALVE
FUNCTION
This hydraulic circuit diagram (Fig. 15) shows a
vehicle equipped with ABS and traction control in
the ABS braking mode. This hydraulic circuit (Fig.
15) shows a situation where one wheel is slipping
because the driver is attempting to stop the vehicle
at a faster rate than the surface the vehicle's tires
are on will allow. The hydraulic shuttle valve (Fig.
15) closes upon brake application so that the pump
can not suck brake fluid from the master cylinder.
The normally open and normally closed valves mod-
ulate the brake hydraulic pressure as required. The
pump/motor is switched on so that the brake fluid
from the low pressure accumulators is returned to
the master cylinder circuits. The brake fluid will
then be routed to either the master cylinder or the
wheel brake depending on the position of the nor-
mally open valve.
