Pad ReplacementNJBR0142WARNING:
Clean brake pads with a vacuum dust collector to minimize the
hazard of airborne particles or other materials.
CAUTION:
+When cylinder body is open, do not depress brake pedal
because piston will pop out.
+Be careful not to damage piston boot or get oil on rotor.
Always replace shims in replacing pads.
+If shims are rusted or show peeling of rubber coat, replace
them with new shims.
+It is not necessary to remove connecting bolt except for
replacement of caliper assembly. In this case, suspend
cylinder body with wire so as not to stretch brake hose.
+Burnish the brake contact surfaces after refinishing or
replacing rotors, after replacing pads, or if a soft pedal
occurs at very low mileage.
Refer to ªBrake Burnishing Procedureº, ªON-VEHICLE
SERVICEº, BR-8.

AdjustmentNJBR0047Before or after adjustment, pay attention to the following points.
+For rear disc brake be sure that toggle lever returns to stop-
per when parking brake lever is released.
+There is no drag when parking brake lever is released.
1. Adjust clearance between shoe and drum/pad and rotor as
follows:
a. Release parking brake lever and loosen adjusting nut.
b. Depress brake pedal fully at least 10 times with engine run-
ning.

2. Pull control lever 10 times or more to make a lever stroke of
195 mm (7.68 in). At8-9notches (Sedan) or 4 to 6 (Hatch-
back) notches, adjust the parking brake cable by turning the
adjusting nut.

3. Pull control lever with specified amount of force. Check lever
stroke and ensure smooth operation.

PurposeNJBR0082The ABS consists of electronic and hydraulic components. It allows for control of braking force so that lock-
ing of the wheels can be avoided.
The ABS:
1) Ensures proper tracking performance through steering wheel operation.
2) Enables obstacles to be avoided through steering wheel operation.
3) Ensures vehicle stability by preventing flat spins.
ABS (Anti-Lock Brake System) OperationNJBR0083+When the vehicle speed is less than 10 km/h (6 MPH) this system does not work.
+The Anti-Lock Brake System (ABS) has self-test capabilities. The system turns on the ABS warning lamp
for 1 second after turning the ignition switch ON. The system performs another test the first time the vehicle
reaches 6 km/h (4 MPH). A mechanical noise may be heard as the ABS performs a self-test. This is a
normal part of the self-test feature. If a malfunction is found during this check, the ABS warning lamp will
come on.
+During ABS operation, a mechanical noise may be heard. This is a normal condition.

System DescriptionNJBR0087SENSORNJBR0087S01The sensor unit consists of a gear-shaped sensor rotor and a sen-
sor element. The element contains a bar magnet around which a
coil is wound. The sensor is installed on the back side of the brake
rotor. Sine-wave current is generated by the sensor as the wheel
rotates. The frequency and voltage increase(s) as the rotating
speed increases.
SBR759E
CONTROL UNITNJBR0087S02The control unit computes the wheel rotating speed by the signal
current sent from the sensor. Then it supplies a DC current to the
actuator solenoid valve. It also controls ON-OFF operation of the
valve relay and motor relay. If any electrical malfunction should be
detected in the system, the control unit causes the warning lamp
to light up. In this condition, the ABS will be deactivated by the
control unit, and the vehicle's brake system reverts to normal
operation.

Self-diagnosis (Only Models with Data Link
Connector Terminal No. 9)
NJBR0091FUNCTIONNJBR0091S01+When a problem occurs in the ABS, the ABS warning lamp on
the instrument panel comes on. To start the self-diagnostic
results mode, ground the self-diagnostic (check) terminal
located on ªData link connectorº. The location of the malfunc-
tion is indicated by the ABS warning lamp flashing.
SELF-DIAGNOSIS PROCEDURENJBR0091S021. Drive vehicle over 30 km/h (19 MPH) for at least one minute.
2. Turn ignition switch ªOFFº.
SEF378Y
3. Ground terminal ª9º of ªData link connectorº with a suitable
harness.
4. Turn ignition switch ªONº while grounding terminal ª9º.
Do not depress brake pedal.
Do not start engine.
SBR759E
5. After 3.0 seconds, the ABS warning lamp starts flashing to
indicate the malfunction code No. (See NOTE.)
6. Verify the location of the malfunction with the malfunction code
chart. Refer to BR-76. Then make the necessary repairs fol-
lowing the diagnostic procedures.
7. After the malfunctions are repaired, erase the malfunction
codes stored in the control unit. Refer to BR-64.
8. Rerun the self-diagnostic results mode to verify that the mal-
function codes have been erased.
SEF378Y
9. Disconnect the check terminal from the ground. The self-diag-
nostic results mode is now complete.
10. Check ABS warning lamp for deactivation after driving vehicle
over 30 km/h (19 MPH) for at least one minute.
11. After making certain that ABS warning lamp does not come on,
test the ABS SELF-DIAGNOSIS in a safe area to verify that it
functions properly.
NOTE:
The indication terminates after five minutes.
However, when the ignition switch is turned from ªOFFº to ªONº, the
indication starts flashing again.

HOW TO READ SELF-DIAGNOSTIC RESULTS
(MALFUNCTION CODES)
NJBR0091S031. Determine the code No. by counting the number of times the
ABS warning lamp flashes on and off.
2. When several malfunctions occur at one time, up to three code
numbers can be stored; the latest malfunction will be indicated
first.
3. The indication begins with the start code 12. After that a maxi-
mum of three code numbers appear in the order of the latest
one first. The indication then returns to the start code 12 to
repeat (the indication will stay on for five minutes at the most).
4. The malfunction code chart is given on the BR-76 page.

ABR256
HOW TO ERASE SELF-DIAGNOSTIC RESULTS
(MALFUNCTION CODES)
NJBR0091S041. Disconnect the check terminal from ground (ABS warning lamp
will stay lit).
2. Within 12.5 seconds, ground the check terminal 3 times. Each
terminal ground must last more than 1 second. The ABS warn-
ing lamp goes out after the erase operation has been com-
pleted.
3. Perform self-diagnosis again. Refer to BR-63. Only the start
code should appear, no malfunction codes.
