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,

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.
