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.

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.
