ADJUSTMENT
Adjustment Procedure
1. Apply the parking brake.
2. Run the engine at idle speed.
3. While you move the shift lever into the reverse
position, depress the clutch pedal slowly and mea-
sure the distance between the point when gear
noise is not heard and the point the clutch pedal is
completely depressed. The distance should be 30
to 40 mm (1.2 to 1.6 inches).
4. If the distance is not within the specified value,
check the following:
S Clutch pedal height
S Clutch pedal play
S Air in the system
S Clutch cover and disc pressure plate
AIR BLEEDING
Bleed the hydraulic system to remove the air which en-
tered when the pipes were disconnected for repairs. The
clutch/brake fluid in the clutch/brake reservoir must be
maintained at the MIN level or higher during air bleeding.
1. Attach a vinyl hose to the bleeder plug. Place the
other end of the vinyl tube in a glass container half–
filled with brake fluid.
2. Slowly pump the clutch pedal several times.
3. While you press the clutch pedal, loosen the bleed-
er screw until the fluid starts to run out. Close the
bleeder screw.
4. Repeat Step 3 until there are no air bubbles in the
fluid.
5. Fill the reservoir with brake fluid up to the proper
level.
PRESSURE PLATE AND CLUTCH
DISC
Removal Procedure
1. Disconnect the negative battery cable.
2. Remove the transaxle from the vehicle. Refer to
Section 5B, Five–Speed Manual Transaxle.
3. Remove the pressure plate bolts and the pressure

SUPPLEMENTAL INFLATABLE RESTRAINTS (SIR) 8B – 89
DAEWOO V–121 BL4
HANDLING, INSTALLATION AND
DIAGNOSIS
S Airbag modules should not be subjected to temper-
ature above 65 degrees Celsius(149 degrees Fahr-
enheit).
S An airbag and SDM should not be used if it has
been dropped from height of 0.9 meters(3 feet) or
greater.
S When an SDM is replaced, it must be oriented with
the arrow on the SDM pointing toward the front of
the vehicle.
S It is very important for the SDM to be installed flat
on the mounting surface, parallel to the vehicle’s
longitudinal axis.
S To avoid setting diagnostic trouble codes(DTCs), do
not apply power to the SIR unless all components
are connected or a diagnostic chart request it.
S The SIR Diagnostic System Check must be the
starting point of any SIR diagnostics. The SIR Diag-
nostic System Check will verify proper airbag indi-
cator operation and will lead you to correct chart to
diagnose any SIR malfunctions. Bypassing these
procedures may result in extended diagnostic time
incorrect parts replacement.
REPAIRS AND INSPECTIONS
REQUIRED AFTER AN ACCIDENT
CAUTION : Any repairs to the vehicle’s structure
must return it to the original production configu-
ration. Deployment requires replacement of
SDM, the inflator modules and a dimensional in-
spection of the steering column.
S If any SIR components are damaged, they must be
replaced. If SIR components mounting points are
damaged, they must be repaired or replaced.
S Never use SIR parts from another vehicle. This
does not include remanufactured parts purchased
from an authorized source.
S Do not attempt to service the SDM, the clock spring
or other airbag modules, these items must be re-
placed if they are defective.
S Verify the part number of replaced airbag modules.
Some inflator modules look identical but contain
different internal components.
