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.

Check pistonforscore, rust,wear, damage orpresence offor-
eign objects. Replace ifany ofthe above conditions are
observed.

CAUTION:
Piston sliding surface isplated. Donot polish withemery paper
even ifrust orforeign objects arestuck tosliding surface.

RUNOUT
1: Secure rotortowheel hubwith atleast twonuts (M12 x
1.25).
2. Check runout usingadial indicator.

Make surethatwheel bearing axialendplay iswithin thespec-
ifications beforemeasuring. RefertoFA section ("FrontWheel
Bearing", "ON-VEHICLE SERVICE").
Maximum runout:
SBR936A 0.07mm(0.0028 in)

3.
If
the runout isout ofspecification, findminimum runout
position asfollows:
a. Remove nutsandrotor fromwheel hub.
b. Shift therotor onehole andsecure rotortowheel hub
with nuts.
c. Measure runout.
d. Repeat stepsa.to c.so that minimum runoutposition can
be found.
4. Ifthe runout isstill outofspecification, turnrotor withon-car
brake lathe("MAD, DL-8700", "AMMCO700and 705" or•••
equivalent).

THICKNESS Thickness variation(Atleast 8positions):
Maximum 0.02mm(0.0008 in)

If thickness variationexceedsthespecification, turnrotor with
on-car brakelathe.

CAUTION:
• When cylinder bodyisopen, donot depress brakepedal,
otherwise pistonwillpop out.
• Becareful nottodamage pistonbootorget oilonrotor.
Always replace shimswhenreplacing pads.
• Ifshims arerusted orshow peeling ofrubber coat,replace
them withnewshims.
• Itis not necessary toremove connecting boltexcept for
disassembly orreplacement ofcaliper assembly. Inthis
case, suspend cylinderbodywithwire soas nol tostreich
brake hose
• Carefully monitorbrakefluidlevel because brakefluidwill
return toreservoir whenpushing backpiston.

1. Remove mastercylinder reservoir cap.
2. Remove brakecablelockspring.
3. Remove cableguide fromcaliper assembly.
4. Disconnect cable.
5. Remove lockspring frombrake hose.Thenremove brake
hose from bracket.
6. Remove lowerpinbolt.
7. Open cylinder bodyupward. Thenremove padretainers,
and inner andouter shims.
