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.

INSPECTION AFTER INSTALLATION

1.

Check a drag of front disc brake. If any drag is found, follow the procedure described below.

2.

Remove brake pads.

3.

Press the piston.

CAUTION:

• Never damage the piston boot.
• When replacing a pad 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 brake pads.

5.

Depress the brake pedal several times.

6.

Check a drag of front disc brake again. If any drag is found, disassemble the cylinder body. Refer to 

BR-

38, "BRAKE CALIPER ASSEMBLY : Disassembly and Assembly"

.

7.

Burnish contact surfaces after refinishing or replacing disc rotors, or if a soft pedal occurs at very low mile-
age. Refer to 

BR-16, "DISC ROTOR : Inspection and Adjustment"

.

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 with power tool.

2.

Remove the upper sliding pin bolt.

3.

Suspend the cylinder body with suitable wire so that the brake hose will not stretch. Remove the brake
pads, shims and shim cover 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.
• Remember each position of the removed brake pads.

REAR DISC BRAKE

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 PBC (Poly Butyl Cuprysil) grease or silicone-based grease to the mating faces between the brake
pads, the shims and pawls part of cylinder body, 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 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 upper 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. Refer
to 

BR-42, "BRAKE PAD : Inspection"

.
