SERVICE PRECAUTIONS

WARNING: DUST AND DIRT ON BRAKE PARTS
GENERATED DURING THE NORMAL USE AND
WEAR OF MOTOR VEHICLE BRAKE SYSTEMS CAN
CONTAIN ASBESTOS FIBERS. BREATHING EXCES-
SIVE CONCENTRATIONS OF ASBESTOS FIBERS
CAN CAUSE SERIOUS BODILY HARM, SUCH AS
ASBESTOSIS

AND

CANCER.

EXTREME

CARE

SHOULD

BE

EXERCISED

WHILE

SERVICING

BRAKE ASSEMBLIES OR COMPONENTS.

DO NOT CLEAN BRAKE ASSEMBLIES OR COM-

PONENTS WITH COMPRESSED AIR OR BY DRY
BRUSHING; USE A VACUUM CLEANER SPECIFI-
CALLY RECOMMENDED FOR USE WITH ASBES-
TOS FIBERS. IF A SUITABLE VACUUM CLEANER IS
NOT AVAILABLE, CLEANING SHOULD BE DONE
WET USING A WATER DAMPENED CLOTH.

DO NOT CREATE DUST BY SANDING, GRINDING,

AND/OR SHAVING BRAKE LININGS OR PADS UN-
LESS SUCH OPERATION IS DONE WHILE USING
PROPERLY EXHAUST VENTILATED EQUIPMENT.

DISPOSE OF ALL DUST AND DIRT SUSPECTED

TO CONTAIN ANY ASBESTOS FIBERS IN SEALED
BAGS OR CONTAINERS TO MINIMIZE DUST EXPO-
SURE TO YOURSELF AND OTHERS.

FOLLOW ALL RECOMMENDED PRACTICES PRE-

SCRIBED BY THE OCCUPATIONAL SAFETY AND
HEALTH ADMINISTRATION AND THE ENVIRONMEN-
TAL PROTECTION AGENCY. FOR THE HANDLING,
PROCESSING, AND DISPOSITION OF DUST OR DIRT
WHICH MAY CONTAIN ASBESTOS FIBERS.

IT IS RECOMMENDED NOT TO BREATH ANY TYPE

OF BRAKE LINING MATERIAL DUST EVEN ASBES-
TOS FREE, DUE TO THE FIBROUS NATURE OF THE
MATERIALS BEING USED.

Grease or any other foreign material must be kept off

caliper assembly, surfaces of braking disc and external
surfaces of hub, during service procedures.

Handling of the braking disc and caliper. Should be

done in such a way as to avoid deformation of the disc
and scratching or nicking of the brake linings.

If inspection reveals that the square sectioned cali-

per piston seal is worn or damaged, it should be
replaced immediately.

During removal and installation of a wheel and tire

assembly, use care not to strike the caliper.

iper away from braking disc using a pry bar or
screwdriver (Fig. 2).

(5) Remove caliper assembly from braking disc and

adapter by sliding the assembly out and away from
the braking disc and adapter (Fig. 3).

(6) Support caliper firmly to prevent weight of cal-

iper from damaging the flexible brake hose (Fig. 4).

material, (Fig. 7). Be sure inboard brake shoe assem-
bly is correctly positioned against anti-rattle clip
(Fig. 6).

(4) Reinstall the Braking Disk on the hub, by in-

stalling it over the wheel studs until it is seated
against the face of the hub (Fig. 6).

(5) Slide the new outboard brake shoe assembly on

the adapter abutment, (Fig. 5).

(6) Carefully lower caliper over the braking disk and

brake shoe assemblies (Fig. 3). Make sure that the
caliper guide pin bolt, bushings and sleeves are clear of
the adapter.

(7) Install the caliper guide pin bolts and tighten to

34 to 37 N

Im (25 to 35 ft. lbs.). Extreme caution

should be taken not to cross the threads of the
caliper guide pin bolts.

(8) Install the wheel and tire assembly. Tighten the

wheel mounting stud nuts in proper sequence (Fig. 9)
until all nuts are torqued to half specification. This is
important. Then repeat the tightening sequence to the
full specified torque of 129 N

Im (95 ft. lbs.).

(9) Remove jackstands or lower hoist. Before mov-

ing vehicle, pump the brake pedal several times
to insure the vehicle has a firm brake pedal to
adequately stop vehicle..

(10) Road test the vehicle and make several stops to
