Inspection After InstallationINFOID:0000000005928399
CAUTION:
• Always disassemble the parts and retighten their fitti ngs, if a brake fluid leak is detected. Replace
applicable part with a new one, if damaged part is detected.
• If leak is detected at the connections, retighten it or replace the damaged part.
1. Check brake hose, tube, and connections for fluid leak s, damage, twisting, deformation, contact with other
parts, and loose connections.
2. While depressing pedal under a force of 785 N (80 kg-f, 177 lb-f) with the engine running for approxi- mately 5 seconds, check for fluid leaks from each part of the brake hydraulic system.

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.
