ROTOR
DIAGNOSIS AND TESTING - BRAKE ROTOR
Any servicing of the rotor requires extreme care to
maintain the rotor within service tolerances to
ensure proper brake action.
Excessive runout or wobble in a rotor can increase
pedal travel due to piston knock-back. This increases
guide pin sleeve wear due to the tendency of the cal-
iper to follow the rotor wobble.
When diagnosing a brake noise or pulsation, the
machined disc braking surface should be checked and
inspected.
BRAKING SURFACE INSPECTION
Light braking surface scoring and wear is accept-
able. If heavy scoring or warping is evident, the rotor
must be refaced or replaced. (Refer to 5 - BRAKES/
HYDRAULIC/MECHANICAL/ROTORS - STAN-
DARD PROCEDURE).
Excessive wear and scoring of the rotor can cause
improper lining contact on the rotor's braking sur-
face. If the ridges on the rotor are not removed before
new brake shoes are installed, improper wear of the
shoes will result.
If a vehicle has not been driven for a period of time,
the rotor's braking surface will rust in the areas not
covered by the brake shoes at that time. Once the
vehicle is driven, noise and chatter from the disc
brakes can result when the brakes are applied.
Some discoloration or wear of the rotor surface is
normal and does not require resurfacing when lin-
ings are replaced. If cracks or burned spots are evi-
dent, the rotor must be replaced.
ROTOR MINIMUM THICKNESS
Measure rotor thickness at the center of the brake
shoe contact surface. Replace the rotor if it is worn
below minimum thickness or if machining the rotor
will cause its thickness to fall below specifications.
CAUTION: Do not machine the rotor if it will cause
the rotor to fall below minimum thickness.
Minimum thickness specifications are cast on the
rotor's unmachined surface (Fig. 93). Limits can also
be found in this section's specification table. (Refer to
5 - BRAKES/HYDRAULIC/MECHANICAL/ROTOR -
SPECIFICATIONS)
ROTOR THICKNESS VARIATION
Thickness variation in a rotor's braking surface
can result in pedal pulsation, chatter and surge. This
can also be caused by excessive runout in the rotor or
the hub.
Rotor thickness variation measurements should be
made in conjunction with measuring runout. Mea-
sure thickness of the brake rotor at 12 equal points
around the rotor braking surface with a micrometer
at a radius approximately 25 mm (1 inch) from edge
of rotor (Fig. 94). If thickness measurements vary
beyond the specification listed in the specifaction
table (Refer to 5 - BRAKES/HYDRAULIC/MECHAN-
ICAL/ROTOR - SPECIFICATIONS), the rotor should
be refaced or replaced. (Refer to 5 - BRAKES/HY-
DRAULIC/MECHANICAL/ROTORS - STANDARD
PROCEDURE).

ROTOR RUNOUT
On-vehicle rotor runout is the combination of the
individual runout of the hub face and the runout of
the rotor. (The hub and rotor runouts are separable).
To measure rotor runout on the vehicle, first remove
the tire and wheel assembly. Reinstall the wheel
mounting nuts on the studs, tightening the rotor to
the hub. Mount the Dial Indicator, Special Tool
C-3339, with Mounting Adaptor, Special Tool SP-
1910 on steering arm. The dial indicator plunger
should contact braking surface of rotor approximately
ten millimeters from edge of rotor (Fig. 95). Check
lateral runout on both sides of the rotor, marking the
low and high spots on both. Runout limits can be
found in the specification table in this section. (Refer
to 5 - BRAKES/HYDRAULIC/MECHANICAL/RO-
TOR - SPECIFICATIONS)
If runout is in excess of the specification, check the
lateral runout of the hub face. Before removing the
rotor from the hub, place a chalk mark across both
the rotor and the one wheel stud closest to where the
high runout measurement was taken. This way, the
original mounting spot of the rotor on the hub is
indexed (Fig. 96).
Remove the rotor from the hub.
NOTE: Clean the hub face surface before checking
runout. This provides a clean surface to get an
accurate indicator reading.Mount Dial Indicator, Special Tool C-3339, and
Mounting Adaptor, Special Tool SP-1910, to the steer-
ing knuckle. Position the indicator stem so it contacts
the hub face near the outer diameter. Care must be
taken to position stem outside of the stud circle, but
inside of the chamfer on the hub rim (Fig. 97).
Hub runout should not exceed 0.03 mm (0.0012
inch). If runout exceeds this specification, the hub
must be replaced. (Refer to 2 - SUSPENSION/
FRONT/HUB / BEARING - REMOVAL)(Refer to 2 -

If the hub runout does not exceed this specifica-
tion, install the rotor back on the hub, aligning the
chalk marks on the rotor with a wheel mounting
stud, two studs apart from the original stud (Fig. 98).
Tighten nuts in the proper sequence and torque to
specifications.Recheck brake rotor runout to see if the runout is
now within specifications. (Refer to 5 - BRAKES/HY-
DRAULIC/MECHANICAL/ROTOR - SPECIFICA-
TIONS)
If runout is not within specifications, reface or
replace the brake rotor. (Refer to 5 - BRAKES/HY-
DRAULIC/MECHANICAL/ROTORS - STANDARD
PROCEDURE)
STANDARD PROCEDURE - BRAKE ROTOR
MACHINING
NOTE: Refacing the rotor is not required each time
the brake pads are replaced, only when the need is
foreseen.
Any servicing of the rotor requires extreme care to
maintain the rotor within service tolerances to
ensure proper brake action.
If the rotor surface is deeply scored or warped, or
there is a complaint of brake roughness or brake
pedal pulsation, the rotor should be refaced using a
hub-mounted on-car brake lathe (Fig. 99), or
replaced.
The use of a hub-mounted on-car brake lathe is
highly recommended to eliminate the possibility of
excessive runout. It trues the brake rotor to the vehi-
cle's hub and bearing.
NOTE: All rotors have markings for minimum allow-
able thickness cast on an un-machined surface of
the rotor (Fig. 100) (Fig. 101). Minimum thickness
specifications can also be found in the specification
table in this section. (Refer to 5 - BRAKES/HY-
DRAULIC/MECHANICAL/ROTOR - SPECIFICATIONS)

Minimum allowable thickness is the minimum
thickness which the brake rotor machined surface
may be cut to.
CAUTION: Do not machine the rotor if it will cause
the rotor to fall below minimum thickness.
Before installation, verify the brake rotor face and
the hub adapters are free of any chips, rust, or con-
tamination.
When mounting and using the brake lathe, strict
attention to the brake lathe manufacturer's operating
instructions is required.
Machine both sides of the brake rotor at the same
time. Cutting both sides at the same time minimizes
the possibility of a tapered or uneven cut.
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. Specifi-
cations for brake rotor machining can be found in
this section's specification table. (Refer to 5 -

PARKING BRAKE
DESCRIPTION
DESCRIPTION
The parking brake system is operated by a foot
operated parking brake lever. The parking brake
lever is mounted on the body of the vehicle to the left
of the brake pedal (Fig. 105). It is a automatic-ad-
justing type lever.

The vehicle has four flexible steel parking brake
cables. They are:
²Front
²Intermediate
²Left rear
²Right rear
The front parking brake cable extends from the
parking brake lever. A steel equalizer bracket con-
nects the front parking brake cable to the left rear
and intermediate cable. The intermediate cable is
connected to the right rear cable using a parking
brake cable connector.
On vehicles equipped with rear drum brakes, the
rear service brakes also act as the vehicle's parking
brakes.
Vehicles equipped with rear disc brakes use a
small duo-servo brake assembly mounted to the each
rear disc brake caliper adapter as the parking brake.
The inside of the brake rotor (hat section of drum-in-
hat style brake rotor) is used as the parking brake
drum.
DESCRIPTION - EXPORT
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.
OPERATION
The automatic-adjusting feature in the foot oper-
ated parking brake lever continuously applies mini-
mal tension to the parking brake cables when the
parking brake lever is in the released position to
keep them in adjustment at all times. Due to this
feature, the parking brake cables require no periodic
adjustment.
When the parking brake lever is applied, the
cables are pulled, thus applying the brake shoes
(rear drum brakes) or parking brake shoes (rear disc
brakes) at each rear wheel.
The brake shoes are mechanically operated by an
internal lever and strut connected to the rear park-
ing brake cables.
An equalizer bracket is used at the rear end of the
front parking brake cable to distribute tension
equally to each parking brake cable.
STANDARD PROCEDURE
STANDARD PROCEDURE - PARKING BRAKE
AUTOMATIC ADJUSTER TENSION RELEASE
The parking brake lever (pedal) mechanism used
in this vehicle is designed so that the automatic
adjuster is not required to be locked out when servic-ing the parking brake lever (pedal) or the parking
brake cables.
This parking brake lever (pedal) mechanism is
designed so that the adjuster mechanism will rotate
only half a turn when the tension is released from
the parking brake cable. This eliminates the require-
ment to lock out the automatic adjuster when servic-
ing the parking brake lever (pedal) mechanism and
cables.
Use the following procedure to release the tension
from the parking brake cables and the automatic
adjuster in the parking brake lever (pedal) mecha-
nism.
(1) 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. 106).
(2) Remove the left rear and intermediate parking
brake cables from the parking brake cable equalizer
(Fig. 107).
(3) Remove the equalizer from the front parking
brake cable.
(4) Remove the locking pliers from the front park-
ing brake cable. This will allow the adjuster in the
parking brake lever (pedal) mechanism to rotate
around to its stop. This will remove the tension from
the adjuster and front park brake cable (Refer to 5 -
BRAKES/PARKING BRAKE - STANDARD PROCE-
DURE).
