2. If the brake pedal play is not within the standard value,
check the following, and adjust or replace if necessary:
DExcessive play between the brake pedal and the clevis
pin, or between the clevis pin and the brake booster
operating rod
DBrake pedal height
DInstallation position of the stop lamp switch, etc.
CLEARANCE BETWEEN BRAKE PEDAL AND FLOOR
BOARD
1. Turn up the carpet etc. under the brake pedal.
2. Start the engine, depress the brake pedal with
approximately 500 N of force, and measure the clearance
between the brake pedal and the floorboard.
Standard value (C): 90 mm or more
3. If the clearance is outside the standard value, check for
air trapped in the brake line and thickness of the disc
brake pad and dragging in the parking brake.
Adjust and replace defective parts as required.
4. Return the carpet, etc.
BRAKE BOOSTER OPERATING TEST
For simple checking of the brake booster operation, carry
out the following tests:
1. Run the engine for one or two minutes, and then stop
it.
If the pedal depresses fully the first time but gradually
becomes higher when depressed succeeding times, the
booster is operating properly. If the pedal height remains
unchanged, the booster is defective.
2. With the engine stopped, step on the brake pedal several
times.
Then start the engine while the brake pedal is stepped
on.
If the pedal moves downward slightly, the booster is in
good condition. If there is no change, the booster is
defective.
3. With the engine running, step on the brake pedal and
then stop the engine.
Hold the pedal depressed for 30 seconds. If the pedal
height does not change, the booster is in good condition.
If the pedal rises, the booster is defective.
If the above three tests are okay, the booster performance
can be determined as good.
If one of the above three tests is not okay at least, the check
valve, vacuum hose, or booster will be defective.

REMEDY FOR A FLAT BATTERY
When booster cables are used to start the engine when the
battery is completely flat and then the vehicle is immediately
driven without waiting for the battery to recharge itself to
some extent, the engine may misfire, and driving might not
be possible. This happens because ABS consumes a great
amount of current for its self-check function. If this happens,
recharge the battery fully.
Caution
The vehicle posture will be unstable during braking, so
do not drive the vehicle with the ABS-ECU connector
disconnected or with the ABS not operating for any other
reason.

STEERING -On-vehicle Service37A-10
9. If the level changes more than 5 mm, the air is badly
bled. So, bleed air again.
Caution
(1) If the fluid level rises suddenly after the engine
is stopped, the bleeding is incomplete.
(2) Incomplete bleeding causes abnormal noises
from the pump and the flow-control valve. This
could lessen the life of the pump and the other
parts.
OIL PUMP PRESSURE TEST
1. Disconnect the pressure hose from the oil pump, and
then connect the special tools.
2. Bleed the air, and then turn the steering wheel several
times while the vehicle is not moving so that the
temperature of the fluid rises to approximately 50 - 60_C.
3. Start the engine and idle it at 1,000±100 r/min.
4. Fully close the shut-off valve of the pressure gauge and
measure the oil pump relief pressure to confirm that it
is within the standard value range.
Standard value: 8.4 - 9.0 MPa
5. If the standard value is not met, the oil pump is defective.
So, replace the oil pump. Then, measure oil pressure
again.
6. With the pressure gauge shut - off valve fully open, check
the hydraulic pressure in unladen condition.
Standard value: 0.2 - 0.8 MPa
7. If the standard value is not met, the oil line or steering
gear is probably defective. So, repair and measure oil
pressure again.
8. Turn the steering wheel fully either left or right and check
the retention hydraulic pressure.
Standard value: 8.4 - 9.0 MPa
9. If the pressure is below the standard value, disassemble
and reassemble the steering gear. If above, replace the
oil pump. Then, measure oil pressure again.
10. Remove the special tools, and tighten the pressure hose
to the specified torque.
Tightening torque: 18±3 N·m
11. Bleed the system.
