Removal and Installation
IDrain oil from vacuum pump before removal.
Manually rotate fan belt clockwise to discharge any oil which
may have accumulated in vacuum pump.
IInstall vane so that its round surface faces pump housing.
IAfter installing vacuum pump assembly, apply 5 m(0.2 Imp fl
oz) of engine oil into vacuum pump assembly. Then, make sure
that pulley can be smoothly rotated by hand.
Inspection
Clean all parts and check them as follows:
ICheck for wear or scratches on mating surfaces of rotor and
vacuum pump housing and on rotor and center plate. If wear
or scratches are noted, replace those parts.
ICheck for wear or scratches on vanes. If necessary, replace.

necessary, replace.
ICheck rotor shaft for wear. If necessary, replace.
ICheck valve locations and copper washers for bends or defor-
mation. If necessary, replace.
ICheck that valve operates smoothly when slightly pushed.
Replace if necessary.
ICheck for air leakage with 98 to 490 kPa (1.0 to 4.9 bar, 1 to
5 kg/cm

Removal and Installation
1. To remove parking brake cable, first remove center console.
2. Disconnect warning lamp connector.
3. Remove bolts, slacken off and remove adjusting nut.
Inspection
1. Check control lever for wear or other damage. Replace if nec-
essary.
2. Check wires for discontinuity or deterioration. Replace if nec-
essary.
3. Check warning lamp and switch. Replace if necessary.
4. Check parts at each connecting portion and, if deformed or
damaged, replace.
Adjustment
1. Adjust clearance between shoe and drum as follows:
a. Release parking brake lever and loosen adjusting nut.
b. Depress brake pedal fully at least 10 times with engine running.
2. Apply the handbrake, allowing the handbrake grip to move 6
notches. You can adjust the handbrake travel by using the
adjusting nut. To complete this adjustment, you will need a
dynamo meter to check the amount of load required to move
from 9 to 10 notches. If the load exceeds 20 kg, the cable will
have to be loosened with the help of the adjusting nut.
Number of notches:
9-10
If the load is less than 20 kg, the cable should be tightened.

PARKING BRAKE CONTROL
BR-35

Purpose
The Anti-lock Brake System (ABS) with an integrated Electronic Brake force Distribution (EBD) system con-
sists of electronic and hydraulic components. It allows you to control the braking force so that wheel lock can
be avoided during braking.
The advantages of ABS with EBD
1) Better tracking performance through improved steering wheel control.
2) Improved maneuverability and safer vehicle control.
3) Improved vehicle stability by preventing flat spins.
4) Shorter stopping distance and optimal utilisation of the rear brakes under many different circumstances.
Operation
IABS with EBD has self-test capabilities. The ABS warning lamp is illuminated for 1 second each time the
ignition switch is turned ªONº. After the engine is started, the ABS warning lamp turns off. An ABS self-test
is performed the first time the vehicle reaches 6 km/h (4 MPH) to ensure the system is operational. A
mechanical noise may be heard as the ABS performs this self-test and is a normal part of the self-test
feature. If a malfunction is detected during this check, the ABS warning lamp will stay on.
During the self-test, it also performs a EBD check when it detects a failure the ABS warning light will go
on simultaneously with the brake warning light and an audible sound will sound constantly.
IEBD system will only operate when the ABS is not in active status and it uses the inlet valves of ABS con-
trol unit to limit the pressure to the rear wheels when they tend to go into slip.
IWhen the vehicle speed is less than 10 km/h (6 MPH) the ABS system does not operate.
IWhile driving, a mechanical noise may be heard during ABS operation, this is a normal system condition.

CONSULT-II Inspection Procedure
SELF-DIAGNOSIS PROCEDURE
1) Turn ignition switch to OFF position.
2) Connect CONSULT-II to Data Link Con-
nector.
1) Start engine.
2) Drive vehicle over 30 km/h (19 MPH)
for at least one minute.
1) Stop vehicle with engine running
and touch ªSTARTº on CON-
SULT-II screen.
2) Touch ªABSº.
3) Touch ªSELF-DIAG RESULTSº.
IThe screen shows the detected malfunc-
tion and how many times the ignition
switch has been turned since the mal-
function.
Make the necessary repairs following the
diagnostic procedures.
After the malfunctions are repaired, erase
the self-diagnostic results stored in the
control unit by touching ªERASEº.
Check warning lamp(s) for deactivation
after driving vehicle over 30 km/h (19
MPH) for at least one minute.
Test the ABS system in a safe area to
verify that it functions properly.
END
Note: ªSELF-DIAG RESULTSº screen shows the detected malfunction and
how many times the ignition switch has been turned since the mal-
function.
