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 because the piston may pop out.
• Never spill or splash brake fluid on the disc rotor.
1.
Remove tires.
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 pad
return spring, brake pads, shims, shim covers and pad retainers from the torque member.
CAUTION:
• Never deform the pad return spring when removing the pad return spring from the brake pad.
• 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.

FRONT DISC BRAKE
• 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 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 (A) and the
inner shim cover (B), 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 (A) and the
outer shim cover (B), 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 (C) and the pad retainers, and Install the brake pads to the torque member.
5.
Install the pad return spring to the brake pad.
CAUTION:
Never deform the pad return spring.
6.
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.
7.
Install the lower sliding pin bolt and tighten it to the specified torque.
8.
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"
.
9.
Install tires.
