NOTE: Use the following information on all 4 wheel
disc brake vehicles that are equipped with BR3
sales code.When refacing a rotor, the required TIR (Total
Indicator Reading) and thickness variation limits
MUST BE MAINTAINED. Extreme care in the oper-
ation of rotor turning equipment is required.

PARKING BRAKE
DESCRIPTION
The parking brake system on this vehicle features
a hand-operated parking brake lever. The lever is
located between the two front seats and requires a
special front cable.

FRONT CABLE
(1) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
(2) Grasp the exposed section of the front parking
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 parking brake cable just rear-
ward of the second body outrigger bracket (Fig. 12).(3) Remove the left rear and intermediate parking
brake cables from the parking brake cable equalizer
(Fig. 13).
(4) Remove the equalizer from the front parking
brake cable.
(5) Remove the locking pliers from the front park-
ing brake cable. This will allow the adjuster in the
parking brake lever mechanism to rotate around to
its stop and remove the tension from the adjuster
and front park brake cable.

²Visual Buzziness (high frequency, rapid vibra-
tion up and down)
To rule out vibrations due to brakes or powertrain:
²Lightly apply brakes at speed; if vibration occurs
or is enhanced, vibration is likely due to causes other
than tire and wheel assemblies.
²Shift transmission into neutral while vibration
is occurring; if vibration is eliminated, vibration is
likely due to causes other than tire and wheel assem-
blies.
For brake vibrations, (Refer to 5 - BRAKES -
BASE/HYDRAULIC/MECHANICAL/ROTORS -
DIAGNOSIS AND TESTING).
For powertrain vibrations, (Refer to 3 - DIFFER-
ENTIAL & DRIVELINE - DIAGNOSIS AND TEST-
ING).
For tire and wheel assembly vibrations, continue
with this diagnosis an testing procedure.
TIRE AND WHEEL BALANCE
(1) Balance the tire and wheel assemblies as nec-
essary following the wheel balancer manufacturer's
instructions and using the information listed in Stan-
dard Procedure - Tire And Wheel Balance. (Refer to
22 - TIRES/WHEELS - STANDARD PROCEDURE)
(2) Road test the vehicle for at least 5 miles, fol-
lowing the format described in Road Test.
(3) If the vibration persists, continue with this
diagnosis an testing procedure.
TIRE AND WHEEL RUNOUT/MATCH MOUNTING
(1)System Radial Runout.This on-the-vehicle
system check will measure the radial runout includ-
ing the hub, wheel and tire.
(a) Raise vehicle so tires clear floor. Refer to
Hoisting in Lubrication and Maintenance.
(b) Apply masking tape around the circumfer-
ence of the tire in the locations to be measured
(Fig. 2). Do not overlap the tape.
(c) Check system runout using Dial Indicator
Set, Special Tool C-3339A with 25-W wheel, or
equivalent. Place the end of the indicator against
each taped area (one at a time) (Fig. 2) and rotate
the tire and wheel. System radial runout should
not exceed 0.76 mm (0.030 inch) with no tread
ªdipsº or ªsteps.º Tread ªdipsº and ªstepsº can be
identified by spikes of the dial indicator gauge.
²Tread9dips9; Rapid decrease then increase in
dial indicator reading over 101.6 mm (4.0 inch) of
tread circumference.
²Tread9steps9; Rapid decrease or increase in dial
indicator reading over 101.6 mm (4.0 inch) of tread
circumference.
(d) If system runout is excessive, re-index the
tire and wheel assembly on the hub. Remove
assembly from vehicle and install it back on thehub two studs over from original mounting posi-
tion. If re-indexing the tire and wheel assembly
corrects or reduces system runout, check hub
runout and repair as necessary (Refer to 5 -
BRAKES - BASE/HYDRAULIC/MECHANICAL/
ROTORS - DIAGNOSIS AND TESTING).
(e) If system runout is still excessive, continue
with this diagnosis an testing procedure.
(2)Tire and Wheel Assembly Radial Runout.
This radial runout check is performed with the tire
and wheel assembly off the vehicle.
(a) Remove tire and wheel assembly from vehicle
and install it on a suitable wheel balancer.
(b) Check system runout using Dial Indicator
Set, Special Tool C-3339A with 25-W wheel, or
equivalent. Place the end of the indicator against
each taped area (one at a time) (Fig. 2) and rotate
the tire and wheel. Radial runout should not
exceed 0.76 mm (0.030 inch) with no tread ªdipsº
or ªsteps.º Tread ªdipsº and ªstepsº can be identi-
fied by spikes of the dial indicator gauge.
(c) If runout exceeds limits, mark the original
location of the tire on the wheel at the valve stem
(Fig. 3). Also, mark the tire and wheel to indicate
the original high spot of the assembly and record
the runout measurement.
(d) If runout exceeds limits, the tire will need to
be dismounted from the wheel to verify wheel vs.
tire contribution. Refer to Wheel Runout below.
(3)Lateral Runout.Lateral runout for the vehi-
cle system as well as the tire and wheel assembly
should be less than 0.76 mm (0.030 inch). The same

(2) Install andlightly tightenthe three remain-
ing wheel mounting nuts, securing the wheel cover in
place (Fig. 25).
(3) Tighten all five wheel mounting nuts in the
proper sequence (Fig. 28). Tighten wheel nuts to a
torque of 135 N´m (100 ft. lbs.).
WHEEL MOUNTING STUDS -
FRONT
REMOVAL
CAUTION: If a wheel mounting stud needs to be
replaced in the hub and bearing assembly, the
studs MUST NOT be hammered out of the hub
flange. If a stud is removed by hammering it out of
the bearing flange, damage to the hub and bearing
assembly will occur leading to premature bearing
failure.
(1) Raise vehicle on jackstands or centered on a
frame contact type hoist. See Hoisting in Lubrication
and Maintenance.
(2) Remove the front wheel and tire assembly from
the vehicle.
(3) Remove the two adapter mounting bolts secur-
ing both the disc brake caliper adapter to the steer-
ing knuckle (Fig. 29).
(4) Remove the disc brake caliper and adapter as
an assembly from the steering knuckle (Fig. 29).
Hang the assembly out of the way using wire or a
bungee cord. Use care not to overextend the brake
hose when doing this.
(5) Remove brake rotor from hub by pulling it
straight off wheel mounting studs (Fig. 29).
(6) On the wheel mounting stud to be removed,
install a wheel mounting (lug) nut far enough so the
threads on the stud are even with end of nut. Install
Remover, Special Tool C-4150A on hub and bearing
assembly flange and wheel stud (Fig. 30).
(7) Tighten down on special tool, pushing wheel
stud out of the hub flange. When shoulder of wheel
stud is past flange, remove special tool from hub and
bearing. Remove nut from stud and remove stud
from hub flange.

INSTALLATION
(1) Install replacement wheel stud into flange of
hub and bearing assembly. Install washers on wheel
stud, then install a wheel mounting (lug) nut on stud
with flat side of lug nut against washers as shown
(Fig. 31).
(2) Tighten the nut, pulling the wheel stud into
the flange of the hub and bearing. When the head ofthe stud is fully seated against the rear of the hub
flange, remove nut and washers from stud.
(3) Install the brake rotor back on the hub and
bearing (Fig. 29).
(4) Install brake caliper and adapter back over
brake rotor aligning adapter with mounting holes on
steering knuckle (Fig. 29).
(5) Install the two adapter mounting bolts securing
the adapter to the steering knuckle. Tighten the
mounting bolts to 169 N´m (125 ft. lbs.) torque.
(6) Install wheel and tire assembly on vehicle.
Tighten the wheel mounting lug nuts in proper
sequence until all nuts are torqued to half specifica-
tion, then repeat the tightening sequence to the full
specified torque of 135 N´m (100 ft. lbs.).
(7) Lower vehicle to the ground.
