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 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 and shim cover from the torque member.
CAUTION:
• Never reuse the pad retainers when removed the pad retainers from the torque member.
• Never damage the piston boot.
• Never drop the brake pads, shims, and the shim cover.
• 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 retainer to the torque member if the pad retainers has been removed.
CAUTION:
• Never reuse the pad retainers.
• Securely assemble the pad retainers so that it will not be lifted up from the torque member.
• Never deform the pad retainers.
• Eliminate double-faced adhesive tape on torque member.
• Remove adhesive's protective liner on pad retainers.
2.
Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease to the mating faces between the brake
pads and pad retainers.
3.
Apply copper based brake grease to the mating faces between the brake 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.
4.
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.
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. Refer
to
BR-36, "BRAKE PAD : Inspection"
.
BRAKE PAD : Inspection
INFOID:0000000005516231
INSPECTION AFTER REMOVAL
Replace the shims and the shim cover 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.
3.
Press the piston.
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 brake pads.
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
38, "BRAKE CALIPER ASSEMBLY : Disassembly and Assembly"
.
7.
Burnish contact surfaces after refinishing or replacing pads, or if a soft pedal occurs at very low mileage.
Refer to
BR-16, "BRAKE PAD : Inspection and Adjustment"
