WARNING:
Clean brakepadswithavacuum dustcollector tominimize the
hazard ofairborne asbestos orother materials.
CAUTION:
Suspend caliperassembly withwire soasnot tostretch brake
hose.

Remove torquemember fixingboltsandconnecting bolt.

It is not necessary toremove connecting boltexcept fordisas-
sembly orreplacement ofcaliper assembly. Inthis case, sus-
pend caliper assembly withwire soas not tostretch brake
hose.
Disassembly
1. Remove pistonbootretainer withascrewdriver.

WARNING: Do not place yourfingers infront ofpiston.
CAUTION: Do not scratch orscore cylinder wall.

2. Push outpiston withdust sealwithcompressed air.
3. Remove pistonsealwith asuitable tool.

Inspection -Caliper
CYLINDER BODY

• Check insidesurface ofcylinder forscore, rust,wear, dam-
age orpresence offoreign objects. Ifany ofthe above con-
ditions areobserved, replacecylinder body.
• Minor damage fromrustorforeign objects maybeelimi-
nated bypolishing surfacewithafine emery paper.Replace
cylinder bodyifnecessary.

CAUTION: Use brake fluidtoclean. Neverusemineral oil.

observed.

CAUTION:
Piston sliding surface isplated. Donot polish withemery paper
even ifrust orforeign objects arestuck tosliding surface.
SLIDE PIN,PINBOLT ANDPINBOOT

Check forwear, cracks, rustorother damage. Replaceifany of
the above conditions areobserved.

Inspection -Rotor
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.

Rotor repair limit:
CL22VD andCL22VE 16.0mm(0.630 in)
CL22VF 24.0mm(0.945 in)
SBR944A Assembly
1. With piston bootfitted topiston, insertpiston bootinto
groove oncylinder bodyandinstall piston.
2. Properly securepistonboot.
3. Secure pistonbootwithretainer.

WARNING:
Clean brakepadswithavacuum dustcollector tominimize the
hazard ofairborne particles orother materials.
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.
