FRONT DISC BRAKE
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.
• 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.
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-34, "BRAKE PAD : Inspection"
.
BRAKE PAD : Inspection
INFOID:0000000003140012
INSPECTION AFTER REMOVAL
Replace the shims and the shim covers 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 pistons.
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
36, "BRAKE CALIPER ASSEMBLY : Disassembly and Assembly"
7.
Burnish contact surfaces after refinishing or replacing brake pads, or if a soft pedal occurs at very low
mileage. Refer to
BR-14, "BRAKE PAD : Inspection and Adjustment"
.
