INSPECTION AFTER DISASSEMBLY

Cylinder Body

Check the inner wall of the cylinder for rust, wear, cracks or damage. Replace the cylinder if any abnormal
condition is detected.

CAUTION:

Always clean with new brake fluid. Never clean with mineral oil such as gasoline and light oil.

Torque Member

Check the torque member for rust, wear, cracks or damage. Replace the member if any abnormal condition is
detected.

Piston

Check the surface of the piston for rust, wear, cracks or damage. Replace the piston if any abnormal condition
is detected.

CAUTION:

A piston sliding surface is plated. Never polish with sandpaper.

Sliding Pin and Sliding Pin Boot

Check the sliding pins and sliding boots for rust, wear, cracks or damage. Replace the parts if any abnormal
condition is detected.

ADJUSTMENT AFTER INSTALLATION

Brake Burnishing Procedure

Burnish contact surfaces between disc rotors and pads according to following procedure after refinishing or
replacing disc rotor, 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 fitted.

• 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 to 3 until pad and disc rotor are securely fitted.

REMOVAL

WARNING:

Clean any dust from the brake caliper and brake pads with a vacuum dust collector. Never blow with
compressed air.

CAUTION:

• Never depress the brake pedal while removing the brake pads or the cylinder body because the pis-

ton may pop out.

• Never spill or splash brake fluid on the disc rotor.
1.

Remove tires.

2.

Remove the lower sliding pin bolt.

3.

Suspend the cylinder body with suitable wire so that the brake hose will not stretch. Remove the brake
pads from the torque member.

CAUTION:

• Never deform the pad retainers if removing the pad retainers.
• Never damage the piston boot.
• Never drop the brake pad, shims, and the shim cover.

INSTALLATION

WARNING:

Clean any dust from the brake caliper and brake pads with a vacuum dust collector. Never blow with
compressed air.

CAUTION:

• Never depress the brake pedal while removing the brake pads or the cylinder body because the pis-

ton may pop out.

• Never spill or splash brake fluid on the disc rotor.

1.

Install the pad retainers to the torque member if the pad retainers has been removed.

CAUTION:

• Securely assemble the pad retainers not to be lifted up from the torque member.
• Never deform the pad retainers.

2.

Apply copper based brake grease to the mating faces between the brake pads and the shims and install
them to the brake pad.

CAUTION:

Always replace the shims together with the shim cover when replacing the brake pad.

3.

Install cylinder body and brake pads to torque member.

CAUTION:

• Never damage the piston boot.
• When replacing a pads with new one, check a brake fluid level in the reservoir tank because

brake fluid returns to master cylinder reservoir tank when pressing piston in.

NOTE:
Use a disc brake piston tool to easily press piston. 

4.

Install the lower sliding pin bolt and tighten it to the specified torque.

5.

Depress the brake pedal several times to check that no drag feel is present for the rear disc brake.
