flared end tubing.PLACE TUBE NUT ON TUB-
ING BEFORE FLARING THE TUBING.
DOUBLE INVERTED TUBING FLARES
To make a double inverted tubing flare (Fig. 39)
and (Fig. 40). Open handles of Flaring Tool, Special
Tool C-4047 or equivalent. Then rotate jaws of tool
until the mating jaws of tubing size are centered
between vertical posts on tool. Slowly close handles
with tubing inserted in jaws but do not apply heavy
pressure to handle as this will lock tubing in place.Place gauge (Form A) on edge over end of brake
tubing. Push tubing through jaws until end of tubing
contacts the recessed notch in gauge matching the
tubing size. Squeeze handles of flaring tool and lock
tubing in place. Place 3/16 inch plug of gauge (A)
down in end of tubing. Swing compression disc over
gauge and center tapered flaring screw in recess of
disc. Screw in until plug gauge has seated on jaws of
flaring tool. This action has started to invert the
extended end of the tubing. Remove gauge and con-
tinue to screw down until tool is firmly seated in tub-
ing. Remove tubing from flaring tool and inspect
seat. Refer to tube routing diagrams for proper brake
tube routing and clip locations. Replace any damaged
tube routing clips.
ISO TUBING FLARES
CAUTION: All ISO style tubing flares (Fig. 39) and
(Fig. 40) are of metric dimensions. When performing
any service procedures on vehicles using ISO style
tubing flares, metric size tubing of 4.75 mm MUST
be used with metric ISO tube flaring equipment.
To create a (metric) ISO style tubing flare, Use
Snap-On Flaring Tool TFM-428, or equivalent. See
(Fig. 41) and proceed with the steps listed below.Be
sure to place the tubing nut on the tube before
flaring the tubing.
(1) Carefully prepare the end of the tubing to be
flared. Be sure the end of the tubing to be flared is
square and all burrs on the inside of the tubing are
removed (Fig. 38).This preparation is essential to

SERVICE PROCEDURES (Continued)
obtain the correct form of a (metric) ISO tubing
flare.
(2) Open jaws of the Flaring Tool. Align the mating
size jaws of the flaring tool around the size of the
tubing to be flared. Close the jaws of the Flaring Tool
around the tubing to keep it from sliding out of the
flaring tool, but do not lock the tubing in place. See
(Fig. 41)
(3) Position the tubing in the jaws of the Flaring
Tool so that it is flush with the top surface of the
flaring tool bar assembly. (Fig. 41) )
(4) Install the correct size adaptor for the brake
tubing being flared, on the feed screw of the yoke
assembly. Center the yoke and adapter over the end
of the tubing. Apply lubricant to the adapter area
that contacts brake tubing. Making sure the adapter
pilot is fully inserted in the end of the brake tubing.
Screw in the feed screw of the yoke assembly until
the adaptor has seated squarely on the surface of the
bar assembly (Fig. 41). This process has created the
(metric) ISO tubing flare.
PARK BRAKE AUTO ADJUSTER MECHANISM
RELEASE
The park brake pedal mechanism used in this vehi-
cle is designed so that the auto adjuster is not
required to be locked out when servicing the park
brake pedal and or the park brake cables.
This park brake pedal mechanism is designed so
that the adjuster mechanism will rotate only half a
turn when the tension is released from the park
brake cable. This eliminates the requirement to lockout the automatic adjuster when servicing the park
brake pedal mechanism and cables.
Use the following procedure to release the tension
from the park brake cables and the auto adjuster in
the park brake pedal mechanism.
(1) Grasp the exposed section of the front park
brake cable and pull rearward on it. While holding
the park brake in this position, install a pair of lock-
ing pliers on the front park brake cable just rearward
of the second body outrigger bracket (Fig. 42).
(2) Remove the left rear and intermediate park
brake cable from the park brake cable equalizer (Fig.
43).
(3) Remove the equalizer from the front park
brake cable.

SERVICE PROCEDURES (Continued)
(4) Remove the locking pliers from the front park
brake cable. This will allow the adjuster in the park
brake pedal mechanism to rotate around to its stop.
This will remove the tension from the adjuster and
front park brake cable.
Use the following procedure to reset the auto
adjuster in the park brake pedal mechanism.
(5) Grasp the exposed section of the front park
brake cable and pull rearward on it. While holding
the park brake in this position, install a pair of lock-
ing pliers on the front park brake cable just rearward
of the second body outrigger bracket (Fig. 42).
(6) Install the equalizer on the front park brake
cable.
(7) Install the left rear and intermediate park
brake cable in the correct location on the park brake
cable equalizer (Fig. 43).
(8) Remove the locking pliers from the front park
brake cable. This will allow the adjuster in the park
brake pedal mechanism to tension the park brake
cables.
(9) Apply and release the park brake pedal one
time. This will seat the park brake cables and allow
the auto adjuster in the park brake pedal mechanism
to correctly tension the park brake cables.
REMOVAL AND INSTALLATION
WHEEL AND TIRE INSTALLATION
To install the wheel and tire assembly, first posi-
tion it properly on the mounting surface using the
hub pilot as a guide. Then progressively tighten thelug nuts in the proper sequence to half of the
required torque. Finally tighten the lug nuts in the
proper sequence to 129 N´m (95 ft. lbs.). Never use
oil or grease on studs or nuts.

SERVICE PROCEDURES (Continued)
(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.

(3) If removed, install the rear rotor on the hub,
making sure it is squarely seated on the face of the
hub.
CAUTION: Use care when installing the caliper
assembly onto the adapter, so the caliper guide pin
bushings do not get damaged by the mounting
bosses.
(4) Carefully lower caliper and brake shoes over
rotor and onto the adapter using the reverse proce-
dure for removal (Fig. 48).
CAUTION: When installing guide pin bolts extreme
caution should be taken not to crossthread the cal-
iper guide pin bolts.

CALIPER INSPECTION
Check for piston seal leaks (brake fluid in and
around boot area and inboard lining) and for any
ruptures of the piston dust boot. If boot is damaged,
or fluid leak is visible, disassemble caliper assembly
and install a new seal and boot, (and piston if
scored). Refer to procedures titled Disc Brake Caliper
Disassembly.
Check the caliper dust boot and caliper pin bush-
ings to determine if they are in good condition.
Replace if they are damaged, dry, or found to be brit-
tle. Refer to Cleaning And Inspection Of Brake Cali-
per.
