BRAKES - BASE
DESCRIPTION
DESCRIPTION - BASE BRAKES
The base brake system consists of the following
components:
²Brake pedal
²Power brake booster
²Master cylinder
²Brake tubes and hoses
²Proportioning valve (non-ABS vehicles only)
²Disc brakes
²Drum brakes
²Brake lamp switch
²Brake fluid level switch
²Parking brakes
Front disc brakes control the braking of the front
wheels; rear braking is controlled by rear drum
brakes or rear disc brakes depending on options.
The hydraulic brake system is diagonally split on
both the non-antilock braking systems and antilock
braking systems. That means the left front and right
rear brakes are on one hydraulic circuit and the right
front and left rear are on the other.
For information on the brake lamp switch, (Refer
to 8 - ELECTRICAL/LAMPS/LIGHTING - EXTERI-
OR/BRAKE LAMP SWITCH - DESCRIPTION)Vehicles equipped with the optional antilock brake
system (ABS) use a system designated Mark 20e. It
is available with or without traction control. This
system shares most base brake hardware used on
vehicles without ABS. ABS components are described
in detail in ANTILOCK BRAKE SYSTEM.DESCRIPTION - BASE BRAKES (EXPORT)
Four-Wheel Disc Antilock Brakes are standard on
all models.
OPERATION - BASE BRAKES
When a vehicle needs to be stopped, the driver
applies the brake pedal. The brake pedal pushes the
input rod of the power brake booster into the booster.
The booster uses vacuum to ease pedal effort as force
is transferred through the booster to the master cyl-
inder. The booster's output rod pushes in the master
cylinder's primary and secondary pistons applying
hydraulic pressure through the chassis brake tubes
to the brakes at each tire and wheel assembly.
The parking brakes are foot-operated. When
applied, the parking brake lever pulls on cables that
actuate brake shoes at each rear wheel. These shoes
come in contact with a hub mounted drum (drum for
disc/drum brakes or drum-in-hat for disc/disc brakes)
and hold it in place.

HYDRAULIC/MECHANICAL
DESCRIPTION
DESCRIPTION - DISC BRAKES (FRONT)
Each front disc brake consists of the following com-
ponents:
²Brake Rotor
²Brake Caliper
²Brake Caliper Adapter
²Shoes (Pads)There are two non-interchangeable front disc brake
systems depending on whether the vehicle is
equipped with rear drum or rear disc brakes. Vehi-
cles with the front disc/rear drum brake combination
utilize a system manufactured by TRW. Vehicles with
front disc/rear disc brakes utilize a system manufac-
tured by Continental Teves.
CAUTION: Components used on the disc/drum
combination brakes are not interchangeable with
the disc/disc combination brakes. The two different
systems must not be mixed. Improper performance,
noise and increased stopping distance can occur.
The TRW front brake caliper is a one piece casting
containing a single 64 mm diameter piston bore (Fig.
5) with a phenolic piston. The caliper mounts to a
caliper adapter using two guide pin bolts that thread
into guide pins slid into the caliper adapter (Fig. 6).
The pins are lubricated and have boots that seal
them in place in the adapter.
The Continental Teves front brake caliper is a one
piece casting containing a single piston 66 mm diam-
eter bore (Fig. 5) with a phenolic piston. The caliper
mounts to a caliper adapter using two guide pin bolts
that thread into the caliper adapter and slide on
bushings mounted in the caliper.

BRAKE FLUID LEVEL SWITCH (Continued)
CAUTION: TRW and Continental Teves calipers are
not interchangeable. Each caliper is specifically
designed for the unique brake system. If calipers
are interchanged, improper performance, noise and
increased stopping distance can occur.
The two different brake calipers use different
devices to control rattling. While the TRW brakes use
spring clips that mount at the ends of the shoes in
the adapters, Continental Teves brakes use a clip on
the rear of the inboard pad to hold it to the piston
and a larger clip on the outside of the caliper, holding
it to the adapter (Fig. 7).
All brake caliper adapters mount to the steering
knuckle in the same way using two mounting bolts.The brake rotors are also different depending on
brake system. The TRW (disc/drum) front brakes uti-
lize an inverted-hat style rotor. This rotor is exter-
nally vented meaning the inner most diameter of the
braking disc vents to the outboard side (or face) of
the rotor (Fig. 8). The Continental Teves (disc/disc)
front brakes utilize the familiar internally-vented hat
style rotor. Internally-vented refers to the fact that
the inner most diameter of the braking disc vents to
the inboard side of the rotor (Fig. 8).
CAUTION: Do not mix rotor types on the same vehi-
cle. If brake rotors are mixed, noise and wear prob-
lems can result.
DESCRIPTION - DISC BRAKES (REAR)
There are several distinctive features to the rear
disc brakes on this vehicle (Fig. 9). The single piston,
floating caliper rear disc brake system includes a hub
and bearing assembly, adapter, rotor, caliper, and
brake shoes.
This vehicle is equipped with a caliper having a 42
mm (1.65 in.) piston and uses a 15 inch solid non-
vented brake rotor. The brake rotor is described as a
drum-in-hat style because of its dual role as a brak-
ing disc and parking brake drum.
The parking brake system on vehicles equipped
with rear disc brakes consists of a small duo-servo
drum brake mounted to the caliper adapter and uses
the interior of the rear disc brake rotor as a drum
(hat section of drum-in-hat style brake rotor).

The outboard rear disc brake shoes (pads) are side-
oriented. The shoes are marked indicating which side
they belong on.
DESCRIPTION - DISC BRAKES (EXPORT)
All vehicles are equipped with Four-Wheel-Disc
brakes. Both 15º (BRE) and 16º (BR3) disc/disc brake
systems are available. The disc brakes are manufac-
tured by Continental Teves. The BR3 system is stan-
dard equipment on all-wheel drive and all right-hand
drive models. It is optional on other models.
The BR3 system features larger, externally vented
front brake rotors.
Although there are different disc/disc systems, they
are serviced using the same service procedures. Some
specifications differ.
DESCRIPTION - DRUM BRAKES (REAR)
This vehicle's rear wheel drum brakes are a two-
shoe, internal-expanding type with an automatic
adjuster screw. The automatic adjuster screw is
located directly below the wheel cylinder that is
mounted near the top of the brake assembly (Fig.
10). These and two brake shoes (and attaching parts)
are mounted to a support plate at each rear wheel. A
brake drum covers each brake assembly.
OPERATION
OPERATION - DISC BRAKES (FRONT)
When the brakes are applied, fluid pressure is sent
to each brake caliper. The pressure at the caliper is
exerted equally against the caliper piston. The pres-sure applied to the piston is transmitted directly to
the inboard brake shoe. This forces the shoe lining
against the inner surface of the brake rotor. At the
same time, fluid pressure within the caliper piston
bore forces the caliper to slide inward on its guide
pins. This action brings the outboard shoe lining into
contact with the outer surface of the brake rotor.
This pressure on both sides of the brake rotor causes
friction, bringing the vehicle to a stop.
When the brake pedal is released, so is the fluid
pressure. The piston seal inside the caliper is
designed to pull the piston back into the bore of the
caliper when the brake pedal is released (Fig. 11).
This action helps maintain the proper brake shoe-to-
rotor clearance.
As disc brake shoe linings wear, master cylinder
reservoir brake fluid level will drop. Adjust as neces-
sary. Fluid level should always be checked after
replacing shoes.
OPERATION - DISC BRAKES (REAR)
The rear disc brakes operate similarly to front disc
brakes, however, there are some features that require
different service procedures.
DIAGNOSIS AND TESTING - DRUM BRAKE
AUTOMATIC ADJUSTER
The rear drum brakes on this vehicle automatically
adjust when required during the normal operation of
the vehicle every time the brakes are applied. Use
the following procedure to test the operation of the
automatic adjuster.
Place the vehicle on a hoist with a helper in the
driver's seat to apply the brakes. Remove the access

plug from the adjustment hole in each brake support
plate to provide visual access of the brake adjuster
star wheel.
To eliminate the condition where maximum adjust-
ment of the rear brake shoes does not allow the auto-
matic adjuster to operate when tested, back the star
wheel off approximately 30 notches. It will be neces-
sary to hold the adjuster lever away from the star
wheel to permit this adjustment.
Have the helper apply the brakes. Upon applica-
tion of the brake pedal, the adjuster lever should
move down, turning the adjuster star wheel. Thus, a
definite rotation of the adjuster star wheel can be
observed if the automatic adjuster is working prop-
erly. If one or more adjusters do not function prop-
erly, the respective drum must be removed for
adjuster servicing.
BRAKE LINES
DESCRIPTION - BRAKE TUBES AND HOSES
The brake tubes are steel with a corrosion-resis-
tant nylon coating applied to the external surfaces.
The flex hoses are made of reinforced rubber with fit-
tings at each end.
The primary and secondary brake tubes leading
from the master cylinder to the ABS ICU Hydraulic
Control Unit (HCU) or the non-ABS junction block
have a special flexible section. This flexible section is
required due to cradle movement while the vehicle is
in motion (The ICU and non-ABS junction block are
mounted to the cradle).If replacement of these
lines is necessary, only the original factory
brake line containing the flexible section must
be used.
OPERATION - BRAKE TUBES AND HOSES
The purpose of the chassis brake tubes and flex
hoses is to transfer the pressurized brake fluid devel-
oped by the master cylinder to the wheel brakes of
the vehicle. The flex hoses are made of rubber to
allow for the movement of the vehicle's suspension.
INSPECTION - BRAKE TUBES AND HOSES
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 brake tubing should be inspected periodically
for evidence of physical damage or contact with mov-
ing 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 must also be inspected. This flexible tub-
ing must be inspected for kinks, fraying and contact
with other components or with the body of the vehi-
cle.
