On-vehicle Service
OPERATING CHECK
1. Depress brake pedal several times with engine off. After
exhausting vacuum, make sure there is no change in pedal
stroke.
2. Depress brake pedal, then start engine. If pedal goes down
slightly, operation is normal.
AIRTIGHT CHECK
1. Start engine, and stop it after one or two minutes. Depress
brake pedal several times slowly. Booster is airtight if pedal
stroke is less each time.
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.
Removal
CAUTION:
lBe careful not to splash brake fluid on painted areas; it
may cause paint damage. If brake fluid is splashed on
painted areas, wash it away with water immediately.
lBe careful not to deform or bend brake pipes, during
removal of booster.

OUTPUT ROD LENGTH CHECK
1. Supply brake booster with vacuum of þ66.7 kPa (þ667 mbar,
þ500 mmHg, þ19.69 inHg) using a hand vacuum pump.
2. Add preload of 19.6N (2.0 kg, 4.4lb) to output rod.
3. Check output rod length.
Specified length:
10.275 - 10.525 mm (0.4045 - 0.4144 in)
Installation
CAUTION:
lBe careful not to deform or bend brake pipes during
installation of booster.
lReplace clevis pin if damaged.
lRefill with new brake fluid ªDOT 4º.
lNever reuse drained brake fluid.
lTake care not to damage brake booster mounting bolt
thread when installing. Due to the acute angle of
installation, the threads can be damaged on the metal
surrounding the dash panel holes.
1. Before fitting booster, temporarily adjust clevis to dimension
shown in the table.

REMOVAL
1. Remove the housing retaining spring.
2. Wipe away any dirt from the guide pins between the torque
member and the cylinder body.
3. Pull out the protective caps from the guide sleeves.
4. Usea7-mmALLEN key to unscrew the guide pins
from the torque member.
5. Partially remove the guide pins from the guide sleeve.
6. Pull the cylinder body manually towards the outer side of the
vehicle so that the piston is slightly pressed back.
7. Remove the cylinder body and hang it on a wire in the wheel
arch in a suitable position.
Make sure there is no strain on the brake hose piping.
8. Remove the brake pad on the piston side from the piston.
9. Remove the second brake pad from the torque member.

Purpose
The Anti-Lock Brake System (ABS) consists of electronic and hydraulic components. It allows for control of
braking force so that locking of the wheels can be avoided.
The ABS:
1) Provides improved steering control during braking (by preventing front wheel lock).
2) Provides improved vehicle stability and skid prevention during braking (by avoiding rear wheel lock).
Operation
lWhen the vehicle speed is less than 10 km/h (6 mph) this system does not work.
lThe Anti-Lock Brake System (ABS) has self-test capabilities. The system turns on the ABS warning light
for 1 second after turning the ignition switch to the ªONº position. 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 light will come on.
lDuring ABS operation, a mechanical noise may be heard. This is a normal operating condition.

System Components
System Description
SENSOR
The sensor unit consists of a gear-shaped sensor rotor and an
electro-magnetic proximity detector. The proximity detector
(ªpick-upº) contains a bar magnet around which a coil is wound.
The detector is installed on the back side of the brake rotor. An
alternating voltage is generated in the coil of the proximity detec-
tor as each tooth of the rotor cuts the magnetic field of the
detector core. The frequency and amplitude of the voltage
increases in proportion to the rotational speed of the rotor.
CONTROL UNIT
The control unit determines the wheel rotating speed from the
signal sent from the sensor, a corresponding control signal is
then output from the control unit in the form of a DC current to
the actuator solenoid valve. The ABS control unit also controls
ON-OFF operation of the valve relay and motor relay. If any
electrical malfunction should be detected in the system, the con-
trol 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.
