(13) Install the proportioning valve to the rear
brake flex hose. Tighten to a torque of 17 N·m (145
in. lbs.).
(14) Install the chassis brake tube to the propor-
tioning valve (Fig. 1). Tighten the tube nut to a
torque of 17 N·m (145 in. lbs.).
(15) Bleed the affected brake line. See Bleeding
Brake System in the Service Adjustments section of
the manual for proper bleeding procedure.
(16) On vehicles with Antilock Brakes, repeat the
above steps for the other proportioning valve.

valves, check the rear wheel brake shoe linings for
contamination or for replacement brake shoes not
meeting OEM brake lining material specifications.
These conditions can also be a possible cause for a
premature rear wheel skid.

REMOVAL AND INSTALLATION
SERVICE WARNINGS AND CAUTIONS
WARNING: ALTHOUGH FACTORY INSTALLED
BRAKE SHOE LININGS ARE MADE FROM ASBES-
TOS-FREE MATERIALS, SOME AFTERMARKET
BRAKE SHOE LININGS MAY CONTAIN ASBESTOS.
THIS SHOULD BE TAKEN INTO ACCOUNT WHEN
SERVICING A VEHICLE’S BRAKE SYSTEM. IT IS
POSSIBLE THAT AFTERMARKET BRAKE SHOES
MAY HAVE BEEN INSTALLED ON THE VEHICLE.
ALWAYS WEAR A RESPIRATOR WHEN CLEANING
BRAKE COMPONENTS; ASBESTOS CAN CAUSE
SERIOUS BODILY HARM SUCH AS ASBESTOSIS
AND CANCER. NEVER CLEAN BRAKE COMPO-
NENTS BY USING COMPRESSED AIR; USE ONLY A
VACUUM CLEANER SPECIFICALLY DESIGNED FOR
THE REMOVAL OF BRAKE DUST. IF A VACUUM
CLEANER IS NOT AVAILABLE, CLEAN BRAKE
PARTS USING ONLY WATER-DAMPENED SHOP
TOWELS. DO NOT CREATE BRAKE LINING DUST
BY SANDING THE BRAKE LININGS WHEN SERVIC-
ING A VEHICLE. DISPOSE OF ALL DUST AND DIRT
SUSPECTED OF CONTAINING ASBESTOS FIBERS.
USE ONLY SEALED AIRTIGHT BAGS OR CONTAIN-
ERS. FOLLOW ALL RECOMMENDED SAFETY
PRACTICES PRESCRIBED BY THE OCCUPATIONAL
SAFETY AND HEALTH ADMINISTRATION (OSHA)
AND THE ENVIRONMENTAL PROTECTION AGENCY
(EPA), FOR HANDLING AND DISPOSING OF PROD-
UCTS CONTAINING ASBESTOS.
CAUTION: Use only MoparT brake fluid or an equiv-
alent from a tightly sealed container. Brake fluid
must conform to DOT 3 specifications. Do not use
petroleum-based fluid because seal damage in the
brake system will result.
CAUTION: Brake fluid will damage painted sur-
faces. If brake fluid is spilled on any painted sur-
faces, wash it off immediately with water.
CAUTION: During service procedures, grease or
any other foreign material must be kept off the cal-
iper assembly, surfaces of the brake rotor and
external surfaces of the hub. Avoid deformation,
scratching or nicking of the brake rotor and brake
shoe linings.
CAUTION: When handling the brake rotor and cali-
per, be careful to avoid damaging the rotor and cal-
iper, and scratching or nicking the brake shoe
lining.
