REFACING BRAKE ROTOR
Refacing of the rotor is not required each time the
brake pads are replaced.
When refacing a rotor the required 0.08 mm (0.003inch) TIR (Total Indicator Reading) and 0.013 mm
(0.0005 inch) thickness variation limits MUST BE
MAINTAINED.Extreme carein the operation of
rotor turning equipment is required.
The use of a double straddle cutter (Fig. 32) that
machines both sides of the rotor at the same time is
highly recommended.
RESURFACNG BRAKE ROTOR
This operation can be used when rotor surface is
rusty, has lining deposits or excessive lateral runout
or thickness variation is evident.
A sanding rotor attachment (Fig. 33) will remove
surface contamination without removing much rotor
material.
It will generally follow variations in thickness that
are in the rotor.

SERVICE PROCEDURES (Continued)

BRAKE DRUM MACHINING
Measure the runout and diameter of the rear brake
using only accurate measuring equipment. There
should be no variation in the drum diameter greater
than 0.090 mm (0.004 inch). Drum runout should not
exceed 0.15 mm (0.006 inch) out of round. If the
drum runout or diameter variation exceed these val-
ues the drum should be refaced. For best results in
eliminating the irregularities that cause brake rough-
ness and surge, the amount of material removed dur-
ing a single cut should be limited to 0.13 mm (0.005
inch). When the entire braking surface has been
cleaned. A final cut of 0.0254 mm (0.001 inch) will
assure a good drum surface providing the equipment
used is capable of the precision required for resurfac-
ing brake drums. Deeper cuts are permissible for the
sole purpose of removing deep score marks.Do not
reface more than 1.52 mm (0.060 inch) over the
standard drum diameter.
All drums will show markings of maximum allow-
able diameter (Fig. 36). For example, a drum will
have a marking of MAX. DIA. 251.55 mm (9.90 inch).
This marking includes 0.76 mm (0.030 inch) for
allowable drum wear beyond the recommended 1.52
mm (0.060 inch) of drum refacing
BRAKE TUBE REPAIR PROCEDURE
CAUTION: When repairing brake chassis lines or
flex hoses, the correct fasteners must be used to
attach the routing clips or hoses to the front sus-
pension cradle. The fasteners used to attach com-
ponents to the front suspension cradle have an
anti-corrosion coating due to the suspension cradle
being made of aluminum. Only Mopar replacement
fasteners with the required anti-corrosion coating
are to be used if a replacement fastener 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 the correct tube nuts are used for the
replacement of these hydraulic brake tubes.
Care should be taken when repairing 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 line from the
master cylinder to the ABS Hydraulic Control Unit,
or the flexible brake lines between the hydraulic con-
trol unit and the proportioning valve require replace-
mentonlythe original factory brake lines containing
a flexible section can be used. This is required due to
the movement of the front suspension cradle while
the vehicle is in motion.
Using Tubing Cutter, Special Tool C-3478-A or
equivalent, cut off damaged seat or tubing (Fig. 37).
Ream out any burrs or rough edges showing on
inside of tubing (Fig. 38). This will make the ends of
tubing square (Fig. 38) and ensure better seating of

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

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.
