REMOVAL

WARNING:

Since dust covering the front brake has an affect on human body, the dust must be removed with a
dust collector. Never splatter the dust with an air blow gun.

CAUTION:

• Never depress the brake pedal while removing the brake pads because the piston may pop out.
• Never spill or splash brake fluid on the disc rotor.

1.

Remove tires with power tool.

2.

Remove lower sliding pin bolt.

3.

Suspend the cylinder body with suitable wire so that the brake hose will not stretch. Then remove the
brake pads, shims, shim covers and pad retainers from the torque member.

CAUTION:

• Never deform the pad retainer when removing the pad retainer from the torque member. 
• Never damage the piston boot.
• Never drop the brake pads, shims, and the shim covers.
• Remember each position of the removed brake pads.

INSTALLATION

WARNING:

FRONT DISC BRAKE

1.

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

CAUTION:

• Securely assemble the pad retainers so that it will not 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 inner
shim and the inner pad, and install them to the inner pad. 

CAUTION:

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

3.

Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease to the mating faces between the outer
shim and the outer shim cover, and install them to the outer pad. 

CAUTION:

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

4.

Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease to the mating faces between the brake
pads and the pad retainers, and Install the brake pads to the torque member.

5.

Install cylinder body to torque member.

CAUTION:

• Never damage the piston boot.
• When replacing brake 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. 

6.

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

7.

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

BR-34, "BRAKE PAD : Inspection"

.

8.

Install tires.

INSPECTION AFTER REMOVAL

Replace the shims and the shim covers if rust is excessively attached.

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. Refer to 

BR-33, "BRAKE PAD : Exploded View"

.

3.

Press the pistons. Refer to

.

4.

Install brake pads. Refer to 

BR-33, "BRAKE PAD : Exploded View"

.

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-

36, "BRAKE CALIPER ASSEMBLY : Disassembly and Assembly"

7.

Burnish contact surfaces brake pads and disc rotor after refinishing or replacing brake pads, or if a soft
pedal occurs at very low mileage. Refer to 

BR-14, "BRAKE PAD : Inspection and Adjustment"

.
