CAUTION:
• Carefully monitorbrakefluidlevel atmaster cylinder.
• Use new brake fluid"DOT 3"or"DOT 4".
• Donot mix different typesofbrake fluids(DOT3,DOT 4).
• Becareful nottosplash brakefluidonpainted areas;itmay
cause paintdamage. Ifbrake fluidissplashed onpaint
areas, washitaway withwater immediately.
• Depress pedalslowly whenraising frontbrake pressure.
• Check rearbrake pressure 2seconds afterfront brake pres-
sure reaches specified value.
• For models withABS disconnect harnessconnectors from
ABS actuator relaybefore checking.

1.
Connect Tooltoair bleeders offront andrear brakes on
either
LH
or
RH
side.
2. Bleed airfrom theTool.
3. Check rearbrake pressure bydepressing brakepedal
(increasing frontbrake pressure).

CAUTION:
• Becareful nottosplash brakefluidonpainted areas;itmay
cause paintdamage. Ifbrake fluidissplashed onpainted
areas, washitaway withwater immediately.
• Inthe case ofbrake fluidleakage fromthemaster cylinder,
disassemble thecylinder. Thencheck piston cupsfordefor-
mation orscratches andreplace necessary parts.

1. Connect avinyl tubetoair bleeder valve.
2. Drain brake fluidfrom each airbleeder valve,depressing
brake pedaltoempty fluidfrom master cylinder.
3. Remove brakepipeflare nuts.
4. Remove mastercylinder mounting nuts.

Inspection

Check master cylinder innerwallforpin holes orscratches.
Replace ifdamaged.

Assembly
1. Insert secondary pistonassembly. Theninsert primary pis-
ton assembly.

• Pay attention todirection ofpiston cupsinfigure atleft.
Also, insert pistons squarely toavoid scratches oncylinder

Description
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.
