Check the pedal height with below
procedures: -
Start the engine and measure the length
(A) between floor mat and pedal.
If the measured value is out of the
specified value, adjust the length. 1.
2.
Adjust the pedal height with below
procedures: -
Disconnect the stop lamp switch connector.
Unscrew the lock nut and remove the stop
lamp switch assembly.
Loosen the lock nut on the pedal push rod.
Turn the pedal push rod to adjust the pedal
height.
Tighten the lock nut.
Install the stop lamp switch assembly.
Connect the stop lamp switch connector.
Check if the stop lamps come on when
pressing the brake pedal around 5 mm.
If the stop lamp dpes not come on, adjust
the stop lamp switch assembly again.
If the stop lamps come on, tighten the lock
nut and measure the pedal height again. 1.

Connect the multimeter to stop lamp
switch connector and check if the
continuity exists when pushing in the
plunger. If the continuity doesn't exist, the
stop lamp switch is normal. - Pedal Free Play ▶
Stop Lamp Switch ▶Check the pedal free play with below
procedures: -
Stop the engine.
Depress the brake pedal several times to
discharge the vacuum pressure of the brake
booster.
Depress the brake pedal until you feel the
resistance, and measure the movement (A). 1.
2.
3.
Below the specified value: Check if the
distance between the outer case of stop
lamp switch and the brake pedal.
Over the specified value: It may be caused
by bigger clearance between the clevis pin
and the brake pedal arm. Replace the
components if necessary. -

Let the engine run for 1 to 2 minutes and
stop it. If the brake pedal stroke is
shortened as pumping the brake pedal,
the system is normal. If not, the system is
defective.
Depress the brake pedal several times
with engine off. If the brake goes down
when starting engine with pedal
depressed, the system is normal. If not,
the system is defective.
Depress the brake pedal when the engine
is running. If the pedal height is not
changed for 30 seconds after stopping
the engine, the system is normal. If not,
the system is defective. 1.

If the above three checks are OK, the system
is normal. If any condition is not met, check
the valve, vacuum hose and brake booster. Brake Booster ▶

Preload is the term used in mechanical engineering to describe the load applied to a fastener
merely as a result of being fastened (and before any external loads are applied)
4. INSPECTION AND MAINTENANCE
Place the wheels at straight ahead
direction.
Lift up the vehicle with a lift.
Unscrew the adjusting plug lock nut.
Measure the torque of the adjusting plug. 1.
2.
3.
4.
If the torque is excessive or too low, adjust
to the specified torque. 5.
Place the rack gear to the center
position.
Tighten the adjusting plug to 10.2 Nm.
Turn the pinion gear so that the rack
gear is turned to lock to lock 5 times.
Unscrew the adjusting plug.
Tighten the adjusting plug to 4.6 to 5.6
Nm.
Unscrew the adjusting plug to 67.5°. -

The difference between both sides should
be within 0.6 kg.Park the vehicle on a paved and flat
ground and place the front wheels at
straight ahead direction.
Start the engine and let it run around 1,000
rpm.
Install the spring scale on the
circumference of the steering wheel and
measure the steering effort in both
directions. 1.
2.
3. Steering Effort Check ▶
Steering Angle Check ▶
Place the front wheel on a turning radius
measuring tool.
Turn the steering wheel to the its both
ends and measure the maximum steering
angle. 1.
2.
If the steering angle is out of the specified
value, check and adjust the toe-in.
Steering angleInner37.59˚
Outer33.48˚
Free Play Check ▶
Start the engine and place the wheels at
straight ahead direction.
Turn the steering wheel until the tires starts
to move and measure the distance on the
circumference of the steering wheel. 1.
2.
If the free play is out of the specified
value, check the free play in steering
column shaft connection and steering
linkage. Replace or repair if necessary.

Oil Change ▶
Open the power fluid reservoir cap and
drain the fluid completely with oil suction
device. To make it easy, turn the steering
wheel to its both ends several times.
Fill up the specified fluid into fluid reservoir
and bleed air from the steering system. 1.
2. Oil Level Check ▶
Place the vehicle on a level ground and
start the engine and let it run at idle speed.
Turn the steering wheel several times so
that the oil temperature reaches to normal
operating level (75~85˚C).
Place the steering wheel at straight ahead
direction.
Check the oil level in the power steering oil
reservoir. Adjust the oil level between MAX
and MIN. 1.
2.
3.
4.
If the difference between two
measurements is below 5 mm and the level
is between MAX and MIN level, it's normal.
If it is over 5 mm, bleed air from the
system. Check the fluid level on a level ground with
the engine turned off. The fluid level should
be between the MIN and MAX marks on the
reservoir cap gauge.

Air Bleeding ▶
Lift up the vehicle very carefully.
Turn the steering wheel to its both ends
several times and add the oil up to MAX
line in the steering oil reservoir.
Periodically crank the starting motor and
turn the steering wheel to its both ends
without any interruption.
Check the oil level again. If the oil level is
fluctuated, repeat the procedures from
step 3 to step 5.
Start the engine.
Turn the steering wheel to its both ends
until any bubble can be found in the
steering oil reservoir.
Perform the test drive and check the
steering wheel for normal operation and
noise.
If the oil level abruptly goes up, bleed the
air from the system again. 1.

The air bleeding should be done after
servicing the power steering system and when
the difference between two measurements
(cooled and normal temperature) is
prominent.

If the air bleeding is not properly
performed, the life span of the power
steering pump may be shortened. -

Oil Pump Pressure Check ▶
Unscrew the pressure line fitting in power
steering pump.
Install the pressure gauge between the
power steering pump and the power
steering oil pressure line.
Place the shift lever to neutral position.
Apply the parking brake.
Open the valve in pressure gauge. Start
the engine and let it run at idle speed.
Turn the steering wheel several times so
that the oil temperature reaches to normal
operating level. 1.

5.
Before checking the pressure, check the oil
level and belt tension. Prepare the empty
container to collect the spilled oil during the
service. Check the oil pump pressure to locate any
defect in oil pump.
Fully close the valve in pressure gauge and
measure the oil pressure. 6.
