EACH TIME THE OIL IS CHANGED
Brake System Inspection
This inspection should be done when the wheels are re-
moved for rotation. Inspect the lines and the hoses for
proper hookup, binding, leaks, cracks, chafing, etc. In-
spect the disc brake pads for wear. Inspect the rotors for
surface condition. Inspect other brake parts, the parking
brake, etc., at the same time. Inspect the brakes more
often if habit or conditions result in frequent braking.
Steering, Suspension and Front Drive Axle
Boot And Seal Inspection
Inspect the front and rear suspension and the steering
system for damaged, loose or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
line and the hoses for proper hookup, binding, leaks,
cracks, chafing, etc. Clean and inspect the drive axle
boot and seals for damage, tears or leakage. Replace
the seals if necessary.
Exhaust System Inspection
Inspect the complete system (including the catalytic
converter if equipped). Inspect the body near the ex-
haust system. Look for broken, damaged, missing, or
out -- of -- position parts as well as open seams, holes,
loose connections, or other conditions which could
cause heat buildup in the floor pan or could let exhaust
fumes seep into the trunk or passenger compartment.
Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding,
damaged, or missing parts. Lubricate all linkage joints
and throttle cable joints, the intermediate throttle shaft
bearing, the return spring at throttle valve assembly, and
the accelerator pedal sliding face with suitable grease.
Check the throttle cable for free movements.
Engine Drive Belts
Inspect all belts for cracks, fraying, wear and proper ten-
sion. Adjust or replace the belts as needed.
Hood Latch Operation
When opening the hood, note the operation of the sec-
ondary latch. It should keep the hood from opening all
the way when the primary latch is released. The hood
must close firmly.
AT LEAST ANNUALLY
Lap and Shoulder Belts Condition and Operation
Inspect the belt system including: the webbing, the
buckles, the latch plates, the retractor, the guide loops
and the anchors.
Movable Head Restraint Operation
On vehicles with movable head restraints, the restraints
must stay in the desired position.
Spare Tire and Jack Storage
Be alert to rattles in the rear of the vehicle. The spare
tire, all the jacking equipment, and the tools must be se-
curely stowed at all times. Oil the jack ratchet or the
screw mechanism after each use.
Key Lock Service
Lubricate the key lock cylinder.
Body Lubrication Service
Lubricate all the body door hinges including the hood,
the fuel door, the rear compartment hinges and the
latches, the glove box and the console doors, and any
folding seat hardware.
Underbody Flushing
Flushing the underbody will remove any corrosive mate-
rials used for ice and snow removal and dust control. At
least every spring clean the underbody. First, loosen the
sediment packed in closed areas of the vehicle. Then
flush the underbody with plain water.
Engine Cooling System
Inspect the coolant and freeze protection fluid. If the
fluid is dirty or rusty, drain, flush and refill the engine
cooling system with new coolant. Keep the coolant at
the proper mixture in order to ensure proper freeze
protection, corrosion protection and engine operating
temperature. Inspect the hoses. Replace the cracked,
swollen, or deteriorated hoses. Tighten the clamps.
Clean the outside of the radiator and the air conditioning
condenser. Wash the filler cap and the neck. Pressure
test the cooling system and the cap in order to help en-
sure proper operation.

2B-6 WHEEL ALIGNMENT
VIBRATION DIAGNOSIS
Wheel imbalance causes most highway speed vibration
problems. A vibration can remain after dynamic balanc-
ing because:
A tire is out of round
A rim is out of round
A tire stiffness variation exists
Measuring tire and wheel free runout will uncover only
part of the problem. All three causes, known as loaded
radial runout, must be checked using method of substi-
tuting known good tire and wheel assemblies on the
problem vehicle.
Tire Balancing
Balance is the easiest procedure to perform and should
be done first if the vibration occurs at high speeds. Do
an off-vehicle, two-plane dynamic balance first to
correct any imbalance in the tire and wheel assembly.
An on-vehicle finish balance will correct any brake drum,
rotor, or wheel cover imbalance, If balancing does not
correct the high-speed vibration, or if the vibration oc-
curs at low speeds, runout is the probable cause.
Preliminary Checks
Prior to performing any work, always road test the car
and perform a careful visual inspection for:
Obvious tire and wheel runout.
Obvious drive axle runout.
Improper tire inflation.
Incorrect trim height.
Bent or damaged wheels.
Debris build-up on the tire or the wheel.
Irregular or excessive tire wear.
Improper tire bead seating on the rim,
Imperfections in the tires, including: tread deforma-
tions, separations, or bulges from impact damage.
Slight sidewall indentations are normal and will not
affect ride quality.

1. Mount the wheel and tire assembly.
2. Install the wheel nuts in the sequence shown. Do
not tighten the wheel nuts .
Installation Notice
Tightening Torque120 Nm (89 lb-ft)
3. Lower the vehicle.
4. Install the wheel cover.
ON-VEHICLE BALANCING
On-vehicle balancing will help correct vibrations due to
brake drum, rotor, and wheel cover imbalances.
Notice: Do not allow the front suspension to hang free.
When the drive axle is run at an extreme angle, extra
vibrations can occur, as well as damage to seals and
joints.
1. During on-vehicle balancing, do not remove the
bal-ance weights from the off-vehicle dynamic
balance.
2. If more than 28.4 grams (1 ounce) of additional
weight is required, split the weight between the inner
and the outer rim flanges.
Caution: Do not spin the drive wheels faster than
55 km/h (35 mph) as indicated by the
speedometer. This limit is necessary because
the speedometer indicates only one-half of the
actual wheel speed when one drive wheel is
spinning and the other drive wheel is stopped.
Personal injury and damage may result from
high-speed spinning.
3. Spin the driven tire and wheel assemblies using
the engine.

4D-2 FRONT BRAKES
DESCRIPTION AND OPERATION
GENERAL DESCRIPTION
When the brakes are applied, fluid pressure is sent to
each brake caliper. The pressure at the caliper is ex-
erted equally against the caliper piston. The pressure
applied to the piston is transmitted directly to the
inboard brake pad. This forces the pad against the inner
surface of the brake rotor. At the same time, fluid
pressure within the caliper piston bore forces the caliper
to slide inward on its guide pins. This action brings the
outboard pad into contact with the outer surface of the
brake rotor. This pressure on both sides of the brake
rotor causes friction, bringing the vehicle to a stop.
BRAKE CALIPER
The caliper has a single bore and is mounted to the
steering knuckle with two mounting bolts. Hydraulic
pressure, created by applying the brake pedal, is con-
verted by the caliper to a stopping force. This force
acts equally against the piston and the bottom of the
caliper bore to move the piston outward and to slide
the caliper inward, resulting in a clamping action on
the rotor. This clamping action forces the linings against
the rotor, creating friction to stop the vehicle.Important:
•Replace all components included in the repair kits
used to service the caliper.
Lubricate the rubber parts with clean brake fluid to
ease assembly.
Do not use lubricated shop air on brake parts, as
damage to the rubber components may result.
If any hydraulic component is removed or discon-
nected, it may be necessary to bleed all or part of
the brake system. Refer to Section 4F, Antilock
Brake System And Traction Control System.
Replace the pads in axle sets only.
The torque values specified are for dry, unlubricated
fasteners.
Perform the service operations on a clean bench,
free from all oily material.
BRAKE PADS
There are two brake pads mounted to each caliper, one
inboard and one outboard. As front disc brake pad wear,
master cylinder reservoir brake fluid level will drop. Fluid
level should be checked after replacing pads.
BRAKE ROTOR
Each front disc brake rotor is vented to help cool it dur-
ing and after brake applications.

DIAGNOSTIC INFORMATION AND PROCEDURES
KAA4D020
PAD INSPECTION
1. Raise and suitably support the vehicle.
2. Remove the front wheel. Refer to Section 2E, Tires
and Wheels.
3. Visually check the linings for minimum thickness
and wear.
4. Measure the thickness.
Important: The minimum discard thickness of the
lining is 2 mm (0.08 inch).
5. Install the pads in axle sets only.
6. Install the rear wheels. Refer to Section 2E, Tires
and Wheels.
7. Lower the vehicle.
FRONT DISC BRAKE ROTOR
INSPECTION
Thickness variation can be checked by measuring the
thickness of the rotor at four or more points around the
circumference of the rotor. All measurements must be
made at the same distance in from the edge of the
rotor.
A rotor that varied by more than 0.013 mm (0.0005
inch) can cause pedal pulsations and/or front end
vibration during brake applications. A rotor that does
not meet these specifications should be refinished to
specifications or replaced.
During manufacturing, the brake rotor and the toler-
ances of the braking surface regarding flatness, thick-
ness variation, and lateral runout are held very close.
The maintenance of close tolerances on the shape of
the braking surfaces is necessary to prevent brake
roughness.In addition to these tolerances, the surface finish must
be held to a specified range. The control of the braking
surface finish is necessary to avoid pulls and erratic
performance and to extend lining life.
Light scoring of the rotor surfaces not exceeding 0.4
mm (0.016 inch) in depth, which may result from normal
use, is not detrimental to brake operation.
Using a commercially available dial indicator, check
lateral runout as follows:
Notice: Permissible lateral runout is a maximum 0.07
mm (0.003 inch). If lateral runout exceeds the specifica-
tion, ensure that there is no dirt between the rotor and
the hub and that contact surfaces are smooth and free
from burrs.
1. Position the transaxle in NEUTRAL.
2. Remove the rotor. Refer to “Rotor” in this section.
3. Fasten the brake rotor to the wheel hub with two
wheel nuts. Refer to Section 2E, Tires and Wheels.
KAA4D030
4. Fasten a dial indicator to the brake caliper.
5. Set the gauge probe tip to approximately 10 mm
(0.394 inch) from the outer edge of the brake rotor,
perpendicular to the disc and under slight preload.
6. Remove the dial indicator and the wheel nuts that
connect the rotor to the hub.
Important: Since accurate control of the tolerances
is necessary for proper performance of the disc
brakes, refinishing of the rotor should be done only
with precision equipment.
7. Refinish the rotor, if required, with precision equip-
ment. Discard the rotor if it fails to meet the above
specifications after refinishing.
8. Install the rotor. Refer to “Rotor” in this section.
