CAUTION:
Clean dust on caliper and brake pad with a vacuum dust collector. Do not blow with compressed air.
While removing brake pad or cylinder body, do not depress brake pedal because piston will pop out.
It is not necessary to remove torque member mounting bolts and brake hose except for disassembly
or replacement of caliper assembly. In this case, hang cylinder body with a wire so that brake hose is
not under tension.
Do not damage piston boot.
If any shim is subject to serious corrosion, replace it with a new one.
Keep rotor free from brake fluid.
When replacing brake pad, replace shim with a new one.
