ton may pop out.

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

1.

Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease to the pad retainers before installing it 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 shims
and the shim cover.

CAUTION:

Always replace the shims 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 brake
pads and pad retainers and install them to the brake pads.

4.

Install cylinder body and brake pads 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:
