• Because vacuum hose contains a check valve, it must be
installed the correct position. Refer to the stamp to confirm
correct installation. Brake booster will not operate normally if
the hose is installed in the wrong direction.
• Insert vacuum hose at least 24 mm (0.94 in) (A).
• Never use lubricating oil during assembly.
• Face the marking side up when assembling.

Hg, 0.39 inHg, 0.013 bar) for 15 seconds under a
vacuum of
−
66.7 kPa (
−
500 mmHg,
−
19.70 inHg,
−
0.667 bar).
When connected to the engine side (C):
Vacuum should not exist.

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
brake pad 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.
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 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 retainer 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 pads, shims and 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 cylinder body and brake pads to the torque member.
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 the lower 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 front disc brake.
6.
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.
3.
Drive without depressing brake for a few minutes to cool the brake.
4.
Repeat steps 1 to 3 until pad and disc rotor are securely fitted.
