• Never drop the brake pads, shims, and the shim covers.
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 because the piston may pop out.
• Never spill or splash brake fluid on the disc rotor.
1.
Apply Copper based brake 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 Copper based brake grease to the mating faces between the shims and the shim covers and install
them to the brake pad.
CAUTION:
Always replace the shims together with the shim covers when replacing the brake pad.
3.
Install the brake pads to the torque member.
CAUTION:
Both inner and outer pads have a pad return system on the
pad retainer. Install pad return lever (1) securely to pad wear
sensor (2).
4.
Install cylinder body to torque member.
CAUTION:
• Never damage the piston boot.
• In the case of 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.
5.
Install the lower sliding pin bolt and tighten it to the specified torque.
6.
Depress the brake pedal several times to check that no drag feel is present for the front disc brake.
7.
Install tires.

Brake Burnishing Procedure
Burnish contact surfaces between pads according to following procedure after refinishing or replacing pads, or
if a soft pedal occurs at very low mileage.
CAUTION:
• Be careful of vehicle speed because the brake does not operate easily until pads 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.
