REMOVAL AND INSTALLATION
Caution
1. Before removing the steering wheel and air bag module assembly, always refer to GROUP
52B - Service Precautions, Air bag Module and Clock Spring. Also, set the front wheels so
that they are facing straight forward, and remove the ignition key. If you fail to do this, the
SRS clock spring will be damaged, causing the SRS air bag to be inoperative and serious
injury.
2. *
1: Indicates parts which should be initially tightened, and then fully tightened after placing
the vehicle horizontally and loading the full weight of the engine on the vehicle body.
3. *
2: Indicates parts which should be temporarily tightened, and then fully tightened with the
vehicle on the ground in the unladen condition.
Caution
If the vehicle is equipped the Brembo disc brake, during maintenance, take care not to contact
the parts or tools to the caliper because the paint of caliper will be scratched.

ON-VEHICLE SERVICE
BRAKE PEDAL CHECK AND ADJUSTMENT
BRAKE PEDAL HEIGHT
1. Turn up the carpet, etc. under the brake pedal.
2. Measure the brake pedal height as illustrated.
Standard value (A): 169.1 - 172.1 mm
3. If the brake pedal height is not within the standard value,
follow the procedure below.
(1) Disconnect the stop lamp switch connector.
(2) Loosen the stop lamp switch by turning it approx.
1/4 turns anticlockwise.
(3) Remove the brake booster. (Refer to P.35A-17.)
NOTE
With the master cylinder and brake pipe connected,
remove the brake booster only.
(4) Adjust the brake pedal height by turning the clevis.
NOTE
When the clevis is turned 180_, the pedal hight is
changed approximately 2.4 mm.
(5) Install the brake booster. (Refer to P.35A-17.)
(6) Measure brake pedal height, and ensure that the
measured value is within the specified value. When
it is out of the specified value, repeat Step (3) - (6).
(7) Insert the stop lamp switch until it’s thread part touches
the stopper. Then lock the stop lamp switch by turning
it approx. 1/4 turns clockwise, and confirm that the
clearance between the switch plunger and the stopper
is as shown.
(8) Connect the connector at the stop lamp switch.
Caution
Check that the stop lamp does not illuminate when
the brake pedal is not depressed.
4. Return the carpet, etc.
BRAKE PEDAL FREE PLAY
1. With the engine stopped, depress the brake pedal two
or three times, After eliminating the vacuum in the power
brake booster, press the pedal down by hand, and confirm
that the amount of movement before resistance is met
(the free play) is within the standard value.
Standard value (B):3–8mm

Stopper
0.5 - 1.0 mm

BASIC BRAKE SYSTEM -On-vehicle Service35A-8
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.

INSTALLATION SERVICE POINT
"AADISC BRAKE ASSEMBLY INSTALLATION

1. In order to measure the brake drag force after pad
installation, measure the rotary-sliding resistance of the
hub by the following procedure with the pads removed.
(1) Withdraw the drive shaft. (Refer to GROUP 26, 27.)
(2) Attach the special tool to the front hub assembly as
shown in the illustration, and tighten it to the specified
torque.
Tightening torque:
245±29 N·m , 225±25 N·m
(3) Use a spring balance to measure the rotary-sliding
resistance of the hub in the forward direction.
2. Install the caliper support to the knuckle, and then
assemble the pad and the clip to the caliper support.
Caution
Do not contaminate the friction surfaces of the pads
and brake discs by any oil or grease.
3. Clean the piston and insert it into the cylinder with the
special tool.
4. Be careful that the piston boot does not become caught,
when lowering the caliper assembly and install the guide
pin to the caliper.
5. Start the engine, and then depress the brake pedal two
or three times strongly. Then stop the engine.
6. Turn the brake disc forward 10 times.
7. Use a spring balance to measure the rotary-sliding
resistance of the hub in the forward direction.
8. Calculate the drag force of the disc brake [difference
between the values measured at steps 1 and 7].
Standard value:
51 N or less , 69 N or less
9. If that drag force exceeds the standard value, disassemble
the piston assembly. Then check the piston for
contamination or rust, and confirm if the piston or the
piston seal is deteriorated, and if the slide pins slide
smoothly.

1. Find the drag force of the disc brake. (Refer to P.35A-13.)
Standard value: 69 N or less
2. If that drag force exceeds the standard value, disassemble
the piston assembly. Then check the piston for
contamination or rust, and confirm if the piston or the
piston seal is deteriorated.MB990998

Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points.
NOTES WITH REGARD TO DIAGNOSIS
1. The phenomena listed in the following table are not abnormal.
PhenomenonExplanation of phenomenon
System check soundWhen starting the engine, a thudding sound can sometimes be heard coming from inside
the engine compartment, but this is because the system operation check is being
performed, and is not an abnormality.
ABS operation sound1. Sound of the motor inside the ABS hydraulic unit operation. (whine)
2. Sound is the generated along with vibration of the brake pedal. (scraping)
3. When ABS operates, sound is generated from the vehicle chassis due to repeated
brake application and release.
(Thump: suspension; squeak: tyres)
System check soundWhen depressing the brake pedal during driving, a shock is sometime felt.
2. For road surfaces such as snow-covered roads and gravel roads, the braking distance for vehicles
with ABS can sometimes be longer than that for other vehicles. Accordingly, advise the customer
to drive safely on such roads by lowering the vehicle speed and not being too overconfident.
3. Diagnosis detection condition can vary depending on the diagnosis code.
Make sure that checking requirements listed in the “Comment” are satisfied when checking the trouble
symptom again.

When not using the MUT-II
NOTE
If the ABS-ECU function has been stopped because of fail-safe
operation, it will not be possible to erase the diagnosis codes.
1. Stop the engine.
2. Use the special tool to earth terminal (1) (diagnosis control
terminal) of the diagnosis connector.
3. Turn on the stop lamp switch. (Depress the brake pedal.)
4. After carrying out steps 1. to 3., turn the ignition switch
to “ON”. Within 3 seconds after turning the ignition switch
to “ON”, turn off the stop lamp switch (release the brake
pedal). Then, turn the stop lamp switch on and off a
total of 10 times.

Faulty ABS operation735B-21
Caution
1. If steering movements are made when driving at high speed, or when driving on road surfaces
with low frictional resistance, or when passing over bumps, the ABS may operate even though
sudden braking is not being applied. Because of this, when getting information from the customer,
check if the problem occurred while driving under such conditions as these.
2. During ABS operation, the brake pedal may vibrate or may not be able to be depressed. Such
phenomena are due to intermittent changes in hydraulic pressure inside the brake line to prevent
the wheels from locking and is not an abnormality.
