Removal and Installation of Brake Caliper and RotorINFOID:0000000005856031
WARNING:
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of air borne
particles or other materials.
CAUTION:
• While removing cylinder bod y, do not depress brake pedal because piston will pop out.
• It is not necessary to remove bolts on torque member and brake hose except for disassembly or
replacement of caliper assembly. In this case, hang cylinder body with a wire so as not to stretch
brake hose.
• Do not damage piston boot.
• If any shim is subject to serious corrosion, replace it with a new one.
• Always replace shim and shim cover as a set when replacing brake pads.
• Keep rotor free from brake fluid.
• Burnish the brake pads and disc rotor mutually contacting surfaces, after refinishing or replacing rotors, after replacing pads, or if a so ft pedal occurs at very low mileage.
REMOVAL
1. Remove front wheel and tires using power tool.
2. Fasten disc rotor using wheel nut.
3. Drain brake fluid. Refer to CO-11, "
Changing Engine Coolant".
4. Remove union bolt, and then disconnect brake hose from caliper assembly.

INFOID:0000000004057221
WARNING:
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of air borne
particles or other materials.
CAUTION:
• While removing cylinder body, do not depress brake pedal because piston will pop out.
• Do not damage piston boot.
• Keep rotor free from brake fluid.
• Refill with new specified brake fluid.
• Burnish brake contact surface after refinishing or re placing rotors, after replacing pads, or it a soft
pedal occurs at very low mileage. Refer to BR-35, "
Brake Burnishing Procedure".
REMOVAL
1. Remove rear wheel and tires using power tools. Refer to WT-41, "Adjustment".
2. Fasten disc rotor using wheel nut.

4. Remove union bolt and cylinder body bolts, then remove cylin- der body.
NOTE:
Discard the copper washers, do not reuse.
5. Apply matching marks to disc rotor and wheel hub assembly if the disc rotor is to be reused, then remove disc rotor.
CAUTION:
Put matching marks on wheel hub assembly and disc rotor
if the disc rotor is to be reused.
INSTALLATION
1. If reusing the disc rotor, use the matching marks to align disc rotor on the wheel hub assembly, then install
disc rotor using a wheel nut to hold it in place.
CAUTION:
Use matching marks on wheel hub assembly and di sc rotor if the disc rotor is to be reused.
2. Install cylinder body and tighten cylinder body bolts to specification. CAUTION:
Before installing cylinder body to the vehic le, wipe off mating surface of cylinder body.
3. Install brake hose to cylinder body with new copper washers and tighten union bolt to specification.
CAUTION:
• Do not reuse copper washers.
• Securely attach brake hose to projection on cylinderbody.
4. Refill with new brake fluid and bleed. Refer to BR-17, "
Bleeding
Brake System".
