(3) Remove the 2 caliper to steering knuckle guide
pin bolts (Fig. 44).
(4) Remove caliper from steering knuckle, by first
rotating free end of caliper away from steering
knuckle. Then slide opposite end of caliper out from
under machined abutment on steering knuckle (Fig.
45).
(5) Support caliper firmly to prevent weight of cal-
iper from being supported by the brake fluid flex
hose. Supporting weight of caliper by the brake fluid
flex hose, can damage the flexible brake hose (Fig.
46).
INSTALL
(1) Lubricate both steering knuckle abutments
with a liberal amount of MopartMultipurpose Lubri-
cant, or equivalent.CAUTION: Use care when installing the caliper
assembly onto the steering knuckle, so the seals on
the caliper guide pin bushings do not get damaged
by the steering knuckle bosses.
(2) Carefully position caliper and brake pad
assemblies over brake rotor by hooking lower or
upper end of caliper over the machined abutment on
steering knuckle (Fig. 45). Then rotate caliper into
position at the top of the steering knuckle (Fig. 45).
Make sure that caliper guide pin bolts, bushings and
sleeves are clear of the steering knuckle bosses.
(3) Install the caliper guide pin bolts (Fig. 44) and
tighten to a torque of 41 N´m (40 ft. lbs.).Extreme
caution should be taken not to cross thread the
caliper guide pin bolts.
(4) Install the wheel and tire assembly.
(5) Using a torque wrench, tighten the wheel
mounting stud nuts in proper sequence until all nuts
are torqued to half specification. Then repeat the
tightening sequence to the full specified torque of 135
N´m (100 ft. lbs.).
(6) Remove jackstands or lower hoist.
(7)Before moving vehicle, pump the brake
pedal several times to insure the vehicle has a
firm brake pedal.
REAR DISC BRAKE CALIPER
During service procedures, grease or any other for-
eign material must be kept off brake shoe assem-
blies, and braking surfaces of rotor.
Handling of the rotor and caliper, must be done in
such a way as to avoid damage to the rotor and
scratching or nicking of lining on the brake shoes.
If inspection reveals that the caliper piston seal is
leaking, itMUSTbe replaced immediately.
During removal and installation of a wheel and
tire assembly, use care not to strike the caliper.

tor bushing on lever of proportioning valve
(Fig. 136) is fully seated in hook of actuator.
NOTE: When installing height sensing proportion-
ing valve on mounting bracket be sure proportion-
ing valve shield (Fig. 135) is installed between the
proportioning valve and the mounting bracket.

that all air has been expelled from the hydraulic sys-
tem. See Bleeding Brake System in the Service
Adjustments section in this group of the service man-
ual for the proper bleeding procedure.
(6) Lower the vehicle to the ground.
(7) Road test the vehicle to verify proper operation
of the vehicles brake system.
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.

SPECIFICATIONS
BRAKE FLUID
The brake fluid used in this vehicle must conform
to DOT 3 specifications and SAE J1703 standards.No other type of brake fluid is recommended or
approved for usage in the vehicle brake system. Use
only Mopar brake fluid or an equivalent from a
tightly sealed container.
CAUTION: Never use reclaimed brake fluid or fluid
from an container which has been left open. An
open container will absorb moisture from the air
and contaminate the fluid.
CAUTION: Never use any type of a petroleum-
based fluid in the brake hydraulic system. Use of
such type fluids will result in seal damage of the
vehicle brake hydraulic system causing a failure of
the vehicle brake system. Petroleum based fluids
would be items such as engine oil, transmission
fluid, power steering fluid ect.
