1. Loosen lock nut and adjust pedal free height by turning brake
booster input rod. Then tighten lock nut.
2. Check pedal free play.
Make sure that stop lamps go off when pedal is released.
3. Check brake pedal's depressed height while engine is running.
If lower than specification, check brake system for leaks, accu-
mulation of air or any damage to components (master cylinder,
wheel cylinder, etc.); then make necessary repairs.

On-vehicle ServiceNJBR0023OPERATING CHECKNJBR0023S011. Stop engine and depress brake pedal several times. Check
that pedal stroke does not change.
2. Depress brake pedal, then start engine. If pedal goes down
slightly, operation is normal.
AIRTIGHT CHECKNJBR0023S021. Start engine, and stop it after one or two minutes. Depress
brake pedal several times slowly. The pedal should go further
down the first time, and then it should gradually rise thereaf-
ter.
2. Depress brake pedal while engine is running, and stop engine
with pedal depressed. The pedal stroke should not change
after holding pedal down for30 seconds.

cylinder head.
a. Apply ThreeBond 1207C (KP510 00150) without breaks to the
location shown in the figure to the left.
SBR632E
b. Tighten the mounting bolts in the numerical order shown by the
figure to the left.
3. Install rear cam sprocket installation bolts.
4. Remove sprocket retaining two M6 bolts.
+M6 bolts will be used for installation.
5. Tighten rear cam sprocket installation bolts.

+Apply ThreeBond 1207C (KP510 00150) without breaks to the
location shown by the figure to the left.
7. Install parts in the reverse order of removal.
CAUTION:
If the engine is started with vacuum pump released (vacuum
hose disconnected), it causes increase of blowby gas amount,
and engine damage may result. When starting the engine, be
sure to close vacuum circuit.

InspectionNJBR0125+Remove vacuum hose. Then, connect vacuum gauge with
three-way connector.
+Install three-way connector to the area where vacuum pump
negative pressure can be directly measured. (The figure
shown an example.)
+Start the engine, then measure negative pressure.
Standard: þ86.6 to þ101.3 kPa (þ866 to þ1,013 mbar,
þ650 to þ760 mmHg, þ25.59 to þ29.92 inHg)
+If it is not within standard, inspect for suction of air in the middle
of route and measure it again.
+If it is still not within standard value, replace the vacuum pump.

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.

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.
