CAUTION: When installing the primary and second-
ary brake tubes on master cylinder, be sure brake
tubes do not contact any other components within
the vehicle and that there is slack in the flexible
sections of the tubes. This is required due to the
movement between the ABS hydraulic control mod-
ule (HCU) and the master cylinder, when the vehicle
is in motion.
(4) Connect the primary and secondary brake
tubes to master cylinder primary and secondary
ports (Fig. 99). Brake tubes must be held securely
when tightened to control orientation of flex section.
Then fully tighten the tube nuts to a torque of 17
N´m (145 in. lbs.).
(5) Install the vehicle wiring harness connector, on
the brake fluid level sensor in the master cylinder
brake fluid reservoir (Fig. 98).
(6) Install filler tube into the master cylinder fluid
reservoir (Fig. 97).
VACUUM BOOSTER 2.4 LITER ENGINE
REMOVE
CAUTION: Reserve vacuum in the vacuum booster
must be pumped down (removed) before removing
master cylinder from vacuum booster. This is nec-
essary to prevent the vacuum booster from sucking
in any contamination as the master cylinder is
removed. This can be done simply by pumping the
brake pedal, with the vehicle's engine not running,
until a firm feeling brake pedal is achieved.
(1) With engine not running, pump brake pedal
until a firm pedal is achieved (4-5 strokes).
(2) Remove both battery cables from battery.

HYDRAULIC BRAKE TUBES AND HOSES
CAUTION: When installing brake chassis lines or
flex hoses on the vehicle, the correct fasteners
must be used to attach the routing clips or hoses to
the front suspension cradle. The fasteners used toattach components to the front suspension cradle
have an antiÐcorrosion coating due to the suspen-
sion cradle being made of aluminum. Only Mopar
replacement fasteners with the required anti-corro-
sion coating are to be used if a replacement fas-
tener is required when installing a brake chassis
line or flex hose.
Only double wall 4.75mm (3/16 in.) steel tubing
with Al-rich/ZW-AC alloy coating and the correct tube
nuts are to be used for replacement of a hydraulic
brake tube.
NOTE: On vehicles equipped with traction control,
the primary and secondary hydraulic tubes between
the master cylinder and the hydraulic control unit
are 6 mm (15/64 in.). These tubes are also coated
with the Al-rich/ZW-AC alloy and must be replaced
with tubes having the same anti-corrosion coating.
Be sure that the correct tube nuts are used for the
replacement of these hydraulic brake tubes.
Care should be taken when replacing brake tubing,
to be sure the proper bending and flaring tools and
procedures are used, to avoid kinking. Do not route
the tubes against sharp edges, moving components or
into hot areas. All tubes should be properly attached
with recommended retaining clips.
If the primary or secondary brake tube from the
master cylinder to the ABS Hydraulic Control Unit
(HCU) or the brake tubes from the HCU to the pro-
portioing valve require replacement,onlythe origi-
nal factory brake line containing the flexible section
can be used as the replacement part. This is required
due to cradle movement while the vehicle is in
motion.

removable from the master cylinder fluid reservoir.
The filler neck if required, can be replaced as a sep-
arate component of the fluid reservoir.
The filler neck is removed and installed using the
following procedure.
REMOVE
(1) Check brake fluid level in master cylinder fluid
reservoir to be sure brake fluid is not in the filler
neck. If brake fluid is in filler neck, lower fluid level
before removing filler neck from fluid reservoir
(2) Grasp filler neck at cap end (Fig. 177) and
push straight down. This will cause the filler neck to
pop out of the fluid reservoir.
INSTALL
(1) Wet the O-ring on the reservoir end of the filler
neck with fresh clean brake fluid.

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.
