Removal and Installation of Brake Pad

INFOID:0000000005147918

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. 

• It is not necessary to disconnect brake hose connection 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 soft pedal occurs at very low mileage.

REMOVAL

1. Remove rear wheel and tires using power tools.
2. Partially drain some brake fluid from the reservoir.
3. Remove the sliding sleeves and sliding pin bolts from the cylinder body.
4. Support the cylinder body with wire, remove pads, shims, cover and retainers. 

INSTALLATION

1. Push piston in using suitable tool.

CAUTION:

By pushing in piston, brake fluid returns to master cylinder reservoir tank. Watch the brake fluid

level in the reservoir tank.

NOTE:

Using a suitable tool, makes it easier to push in the piston.

3. Install pads, shims, cover and retainers to cylinder body.
4. Apply rubber grease to the sliding sleeves and install cylinder body, sliding sleeves and sliding pin bolts

and tighten to specification. Refer to

Brake Burnishing Procedure

INFOID:0000000005147919

Burnish contact surfaces between disc rotors and pads according to following procedure after refinishing or

replacing rotors, after replacing pads, or if a soft pedal occurs at very low mileage.

CAUTION:

• Be careful of vehicle speed because the brake does not operate easily until pad and disc rotor are

securely seated.

• Only perform this procedure under safe road and traffic conditions. Use extreme caution.

1. Drive vehicle on straight, flat road. 

2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.

3. Drive without depressing brake for a few minutes to cool the brake.

4. Repeat steps 1 through 3 until pad and disc rotor are securely seated.
