NOTE: The following wheel sequence should be
used when bleeding the brake hydraulic system.
The use of this wheel sequence will ensure ade-
quate removal of all trapped air from the brake
hydraulic system.
²Left Rear Wheel
²Right Front Wheel
²Right Rear Wheel
²Left Front Wheel
NOTE: When bleeding the brake system, some air
may be trapped in the brake lines or valves far
upstream, as much as ten feet from the bleeder
screw (Fig. 2). Therefore, it is essential to have a
fast flow of a large volume of brake fluid when
bleeding the brakes to ensure all the air gets out.
The brakes may be manually bled or pressure bled.
Refer to the appropriate following procedure.
MANUAL BLEEDING PROCEDURE
NOTE: Correct manual bleeding of the brakes
hydraulic system will require the aid of a helper.
NOTE: To adequately bleed the brakes using the
manual bleeding procedure the rear brakes must be
correctly adjusted. Prior to the manual bleeding of
the brake hydraulic system, correctly adjust the
rear brakes.
(1) Pump the brake pedal three or four times and
hold it down before the bleeder screw is opened.
(2) Push the brake pedal toward the floor and hold
it down. Then open the left rear bleeder screw at
least 1 full turn. When the bleeder screw opens the
brake pedal will drop all the way to the floor.CAUTION: ªJust crackingº the bleeder screw often
restricts fluid flow, allowing only a slow, weak fluid
discharge of fluid. This practice will NOT get all the
air out. Make sure the bleeder is opened at least 1
full turn when bleeding.
(3) Release the brake pedal onlyafterthe bleeder
screw is closed.
(4) Repeat steps 1 through 3, four or five times, at
each bleeder screw in the proper sequence. This
should pass a sufficient amount of fluid to expel all
the trapped air from the brake system. Be sure to
monitor the fluid level in the master cylinder, so it
stays at a proper level so air will not enter the brake
system through the master cylinder.
(5) Check pedal travel. If pedal travel is excessive
or has not been improved, enough fluid has not
passed through the system to expel all the trapped
air. Continue to bleed system as necessary.
(6) Perform a final adjustment of the rear brake
shoes (when applicable), then test drive vehicle to be
sure brakes are operating correctly and that pedal is
solid.
PRESSURE BLEEDING PROCEDURE
CAUTION: Use bleeder tank Special Tool C-3496-B
or equivalent with Adapter, Special Tool 6921, to
pressurize the hydraulic system for bleeding.
Follow pressure bleeder manufacturer's instruc-
tions for use of pressure bleeding equipment.
(1) Install the Adapter Master Cylinder Pressure
Bleed Cap, Special Tool 6921 on the fluid reservoir of
the master cylinder (Fig. 3). Attach the fluid hose
from the pressure bleeder to the fitting on Special
Tool 6921.
(2) Attach a clear plastic hose to the bleeder screw
at one wheel and feed the hose into a clear jar con-
taining fresh brake fluid.
(3) Open the left rear wheel bleeder screw at least
one full turnor more to obtain an adequate flow of
brake fluid.
CAUTION: ªJust crackingº the bleeder screw often
restricts fluid flow, allowing only a slow, weak fluid
discharge of fluid. This practice will NOT get all the
air out. Make sure the bleeder is opened at least 1
full turn when bleeding.
(4) After 4 to 8 ounces of brake fluid has been bled
through the hydraulic system, and an air-free flow is
maintained in the hose and jar, this will indicate a
good bleed of the hydraulic system has been
obtained.
(5) Repeat the procedure at all the other remain-
ing bleeder screws.

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.

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
