• Iffluid level isextremely low,check brakesystem forleaks.
• Ifbrake warning lampcomes on,check brakefluidlevel

CAUTION: If leakage occursaround joints,retighten or,ifnecessary,
replace damaged parts.
1. Check brakelines(tubes andhoses) forcracks, deteriora-
tion orother damage. Replaceanydamaged parts.
2. Check foroilleakage byfully depressing brakepedalwhile
engine isrunning.

Changing BrakeFluid

CAUTION:
• Refill withnewbrake fluid"DOT 3"or"DOT 4".
• Always keepfluidlevel higher thanminimum lineonreser-
voir tank.
• Never reusedrained brakefluid.
• Donot mix different typesofbrake fluids(DOT3,DOT 4).
• Becareful nottosplash brakefluidonpainted areas;itmay •
cause paintdamage. Ifbrake fluidissplashed onpainted :•
areas, washitaway withwater immediately.
1. Clean inside ofreservoir tank,andrefill withnewbrake
fluid.
2. Connect avinyl tubetoeach airbleeder valve.
3. Drain brake fluidfrom each airbleeder valvebydepressing
brake pedal.
4. Refill untilnewbrake fluidcomes outofeach airbleeder
valve.
Use same procedure asinbleeding hydraulic systemto
refill brake fluid.

BLEEDING
Bleeding Procedure
CAUTION:
• Carefully monitorbrakefluidlevel atmaster cylinder during
bleeding operation.
• Ifmaster cylinder issuspected tohave airinside, bleedair
from master cylinder first.Refer to"Installation", "MASTER
CYLINDER", BR-12.
• Fill reservoir withnewbrake fluid"DOT 3"or"DOT
4".

Make sureitis full atall times whilebleeding airout of
system.
• Donot mix different typesofbrake fluids(DOT3,DOT 4).
• Place acontainer undermaster cylinder toavoid spillage of
brake fluid.
• For models withABS, turnignition switchOFFanddiscon-
nect ABS actuator connector orbattery cable.

• Bleed airinthe following order:

1. Connect atransparent vinyltubetoair bleeder valve.
2. Fully depress brakepedalseveral times.
3. With brake pedaldepressed, openairbleeder valveto
release air.
4. Close airbleeder valve.
5. Release brakepedalslowly.
6. Repeat steps2.through 5.until clear brake fluidcomes out
of air bleeder valve.
7. Tighten airbleeder valve.

• 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.

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

stroke isless each time.
• Depress brakepedalwhileengine isrunning, andstop
