OPERATING CHECK

• Depress brakepedalseveral timeswithengine off.After
exhausting vacuum,makesurethere isno change inpedal
stroke.
• Depress brakepedal, thenstart engine. Ifpedal goesdown
slightly, operation isnormal.

AIRTIGHT CHECK

• Start engine, andstop itafter oneortwo minutes. Depress

brakepedalseveral timesslowly. Booster isairtight ifpedal
stroke isless each time.
• Depress brakepedalwhileengine isrunning, andstop
engine withpedal depressed. Thepedal stroke should not
change afterholding pedaldownfor
30seconds.
SBR365AA Removal
CAUTION:
• Becareful nottosplash brakefluidonpainted areas;itmay
cause paintdamage. Ifbrake fluidissplashed onpainted
areas, washitaway withwater immediately.
• Be careful nottodeform orbend brake pipes, during
removal ofbooster.

OUTPUT RODLENGTH CHECK

1. Supply brakebooster withvacuum of-66.7 kPa(-667 mbar,
-500 mmHg, -19.69inHg)usingahand vacuum pump.
2. Check output rodlength.
Specified length:
M195, S205orC205
10.275 -10.525 mm(0.4045 -0.4144 in)
Installation
CAUTION: • Becareful nottodeform orbend brake pipesduring instal-
lation ofbooster.
• Replace clevispinifdamaged.
• Refill withnewbrake fluid"DOT 3"or"DOT 4".
• Never reusedrained brakefluid.
• Donol mix different typesofbrake fluids(DOT3,DOT 4).
• Due tothe angle ofinstallation, threadcanbedamaged by
the dash panel.
1. Before fittingbooster, temporarily adjustclevistodimen-
sion shown. (Doesnotapply tovehicles fittedwithABS.)
2. Fitbooster, thensecure mounting nuts(brake pedalbracket
to booster) lightly.
3. Connect brakepedalandbooster inputrodwith clevis pin.
4. Secure mounting nuts.
Specification:
~: 13-16 N'm (1.3-1.6 kg-m, 9-12 ft-Ib)
5. Install master cylinder. RefertoBR-12.
6. Bleed air.Refer to"Bleeding Procedure", BR-6.

ANTI-LOCKBRAKESYSTEM
Purpose

The Anti-Lock BrakeSystem (ABS)consists ofelectronic andhydraulic components. Itallows forcon-
trol ofbraking forcesothat locking ofthe wheels canbeavoided.
The ABS:
1) Improves propertracking performance throughsteering wheeloperation.
2) Eases obstacles tobe avoided throughsteering wheeloperation.
3) Improves vehiclestability bypreventing flatspins.

Operation

• When thevehicle speedisless than 10km/h (6MPH) thissystem doesnotwork.
• The Anti-Lock BrakeSystem (ABS)hasself-test capabilities. Thesystem turnsonthe ABS warning
light for1second afterturning theignition switchON.The system performs anothertestthefirst time
the vehicle reaches 6km/h (4MPH). Amechanical noisemaybeheard asthe ABS performs aself-
test. This isanormal partofthe self-test feature.Ifa malfunction isfound during thischeck, theABS
warning lightwillcome on.
• During ABSoperation, amechanical noisemaybeheard. Thisisanormal condition.

SENSOR

The sensor unitconsists ofagear-shaped sensorrotoranda
sensor element. Theelement contains abar magnet around
which acoil iswound. Thesensor isinstalled onthe back side
of the brake rotor.Sine-wave currentisgenerated bythe sen-
sor asthe wheel rotates. Thefrequency andvoltage increase(s) •
as the rotating speedincreases. :•

V: Induced electromotive force

SBR124B
SBR049DA CONTROL
UNIT

The control unitcomputes thewheel rotating speedbythe sig-
nal current sentfrom thesensor. Thenitsupplies aDC current
to the actuator solenoid valve.Italso controls ON-OFFopera-
tion ofthe valve relayandmotor relay.Ifany electrical malfunc-
tion should bedetected inthe system, thecontrol unitcauses
the warning lamptolight up.Inthis condition, theASS willbe
deactivated bythe control unit,andthevehicle's brakesystem
reverts tonormal operation.
