DIAGNOSTIC INFORMATION AND PROCEDURES
TIRE DIAGNOSIS
Irregular and Premature Wear
Irregular and premature tire wear has many causes.
Some of them are incorrect inflation pressures, lack of
regular rotation, poor driving habits, or improper wheel
alignment.
Rotate the tires if :
•The front tire wear is different from the rear.
The left and right front tire wear is unequal.
The left and right rear tire wear is unequal.
Check wheel alignment if :
The left and right front tire wear is unequal.
The wear is uneven across the tread of either front
tire.
The front tire treads are scuffed with “feather” edges
on the side of the tread ribs or blocks.
Tread Wear Indicators
The original equipment tires have built-in tread wear in
dicators to show when the tires need replacement.
These indicators appear as bands when the tire tread
depth becomes shallow. Tire replacement is recom
mended when the indicators appear in three or more
grooves at six locations.
KAA2B010
Radial Tire Waddle
Waddle is side-to-side movement at the front or rear of
the vehicle. It is caused by the steel belt not being
straight within the tire, or by excessive lateral runout
of the tire or wheel.
The vehicle must be road tested to determine which
end of the vehicle has the faulty tire. The rear end of
the vehicle will shake from side to side or “waddle” if
the waddle tire is on the rear of the vehicle. From the
driver’s seat, it feels as though someone is pushing
on the side of the vehicle.
If the faulty tire is on the front of the vehicle, the waddle
is more visual. The front sheet meld appears to be mov-
ing back and forth, and the drivers seat feels like the
pivot point in the vehicle.
Waddle can be diagnosed using the method of substitut-
ing known good tire and wheel assemblies on the prob-
lem vehicle.
1. Road test the vehicle to determine if the waddle is
coming from the front or the rear of the vehicle.
2. Install good tires and wheels from a similar vehicle
in place of those on the offending end of the problem
vehicle. If the source of the waddle is not obvious,
change the rear tires.
3. Road test the vehicle. If there is improvement,
install the original tires to find the offending tire. If
there is no a straight improvement, install good tires
in place of all four offending tires.

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.

2E-4 TIRE AND WHEELS
TIRE LABEL
The tire label is permanently located on the rear face
of the driver’s door and should be referred to for tire
information. It lists the maximum vehicle load, the tire
size (including the spare tire), and the cold inflation
pressure (including the spare tire).
S PARE TIRE
This vehicle comes equipped with a full-sized spare
tire and wheel.
The temporary spare tire is designed for emergency
use only. The original tire should be repaired or replaced
at the first opportunity and reinstall.
WHEELS
Wheels must be replaced if they are bent, dented, have
excessive lateral or radial runout, leak air through
welds, have elongated bolt holes, or if the wheel bolts
won’t stay tight or are heavily rusted. Wheels with
excessive runout may cause vehicle vibration.
Replacement wheels must be equivalent to the original
equipment wheels in load capacity, diameter, rim width,
offset, and mounting configuration. A wheel of improper
size or type may affect wheel and bearing life, brake
cooling, speedometer/odometer calibration, vehicle
ground clearance, and tire clearance to the body and
the chassis. The wheel offset is 49 ± 1 (1.93 ± 0.04
inches). Steel wheels may be identified by a two- or
three-letter code stamped into the rim near the valve
stem. Alloy wheels should have the code, the part
number, and the manufacturer ID cast into the back
side.
INFLATION OF TIRES
The pressure recommended for any vehicle line is care-
fully calculated to give a satisfactory ride, handling,
tread life, and load-carrying capacity.
Tire pressure should be checked monthly or before any
extended trip. Check the tires when they are cold, after
the vehicle has sat for 3 hours or more or has been
driven less than 1 mile. Set the tire pressure to the
specifications on the tire label located on the rear face
of the drive r ’s door. Tire inflation pressure is also given
under “Tire Size and Pressure Specifications” in
this section.
Valve caps or extensions should be on the valves to
keep dust and water out.
For sustained driving at speeds up to 140 km/h (85 mph),
inflate the tires to the pressure recommended on the
tire. Sustained driving at speeds faster than 140 km/h
(85 mph), even if permitted by law, is not advised unless
the vehicle has special high-speed tires available from
many tire dealers. Tire pressures may increase as much
as 41 kPa (6 psi) when the tires are hot.
Higher than recommended tire pressure can cause
Hard ride.
Tire bruising or damage.
Rapid tread wear at the center of the tire.
Lower than recommended pressure can cause
Tire squeal on turns.
Hard steering.
Rapid and uneven wear on the edges of the tread.
Tire rim bruises and rupture.
Tire cord breakage.
High tire temperatures.
Unequal tire pressures on same axle can cause
Uneven braking.
Steering lead.
Reduced handling.
Swerve on acceleration.
Torque steer.

HYDRAULIC BRAKES 4A-3
SSANGYONG MY2002
DIAGNOSTIC INFORMATION AND PROCEDURES
BRAKE SYSTEM TESTING
Brakes should be tested on a dry, clean, reasonably
smooth and level roadway. A true test of brake perfor-
mance cannot be made if the roadway is wet, greasy,
or covered with loose dirt which can cause tires not to
grip the road unequally. Testing also will be inaccurate
on a crowned roadway because the wheels tend to
bounce.
Test the brakes at different vehicle speeds with both
light-and heavy-pedal pressure; however, avoid locking
the brakes and sliding the tires. Locked brakes and
slid-ing tires do not indicate brake efficiency since
heavily braked but turning wheels will stop the vehicle
in less distance than locked brakes. More tire-to-road
friction is present with a heavily braked, turning tire
than with a sliding tire.
Because of the high deceleration capability, a firmer
pedal may be felt at higher deceleration levels.
There are three major external conditions that affect
brake performance:
•Tires having unequal contact and grip of the road
will cause unequal braking. Tires must be equally
inflated, and the tread pattern of the right and the
left tires must be approximately equal.
Unequal loading of the vehicle can affect the brake
performance since the most heavily loaded wheels
require more braking power, and thus more braking
effort, than the others.
Misalignment of the wheels, particularly conditions
of excessive camber and caster, will cause the
brakes to pull to one side.
To check for brake fluid leaks, hold constant foot pres-
sure on the pedal with the engine running at idle and
the shift lever in NEUTRAL. If the pedal gradually falls
away with the constant pressure, the hydraulic system
may be leaking. Perform a visual check to confirm any
suspected leaks.
Check the master cylinder fluid level. While a slight
drop in the reservoir level results from normal lining
wear, an abnormally low level indicates a leak in the
system. The hydraulic system may be leaking either
internally or externally. Refer to the procedure below
to check the master cylinder. The system may appear
to pass this test while still having a slight leak. If the
fluid level is normal, check the vacuum booster pushrod
length. If an incorrect pushrod length is found, adjust
or replace the rod.Check the master cylinder using the following proce
dure:
Check for a cracked master cylinder casting or a
brake fluid leak around the master cylinder. Leaks
are indicated only if there is at least one drop of
fluid. A damp condition is not abnormal.
Check for a binding pedal linkage and for an
incorrect pushrod length. If both of these parts are
in satisfactory condition, disassemble the master
cylinder and check for an elongated or swollen
primary cylinder or piston seals. If swollen seals
are found, substandard or contaminated brake fluid
should be suspected. If contaminated brake fluid
is found, all the components should be
disassembled and cleaned, and all the rubber
components should be replaced. All of the pipes
must also be flushed.
Improper brake fluid, or mineral oil or water in the fluid,
may cause the brake fluid to boil or cause deterioration
of the rubber components. If the primary piston cups in
the master cylinder are swollen, the rubber parts have
deteriorated.
If deterioration of the rubber is evident, disassemble
all the hydraulic parts and wash the parts with alcohol.
Dry these parts with compressed air before reassembly
to keep the alcohol out of the system. Replace all the
rubber parts in the system, including the hoses. When
working on the brake mechanisms, check for fluid on
the linings. If excessive fluid is found, replace the
linings.
If the master cylinder piston seals are in satisfactory
condition, check for leaks or excessive heat conditions.
If these conditions are not found, drain the fluid, flush
the master cylinder with brake fluid, refill the master
cylinder, and bleed the system.
BRAKE HOSE INSPECTION
The hydraulic brake hoses should be inspected at least
twice a year. The brake hose assembly should be
checked for road hazard damage, cracks, chafing of
the outer cover, and for leaks or blisters. Inspect the
hoses for proper routing and mounting. A brake hose
that rubs on a suspension component will wear and
eventually fail. A light and a mirror may be needed for
an adequate inspection. If any of the above conditions
are observed on the brake hose, adjust or replace the
hose as necessary.
