REAR BRAKE
INTRODUCTION
WARNING
Disc brake components rarely require disas-
sembly. Therefore, always follow these pre-
ventive measures:
Never disassemble brake components un-
less absolutely necessary.
If any connection on the hydraulic brake
system is disconnected, the entire brake
system must be disassembled, drained,
cleaned, properly filled, and bled after reas-
sembly.
Never use solvents on internal brake com-
ponents.
Use only clean or new brake fluid for clean-
ing brake components.
Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean
up any spilt brake fluid immediately.
Avoid brake fluid coming into contact with
the eyes as it can cause serious injury.
FIRST AID FOR BRAKE FLUID ENTERING
THE EYES:
Flush with water for 15 minutes and get im-
mediate medical attention.
CHECKING THE REAR BRAKE DISC
1. Remove:
• Rear wheel
Refer to “REAR WHEEL” on page 4-12.
2. Check:
• Brake disc
Damage/galling
→
Replace.
3. Measure:
• Brake disc deflection
Out of specification
→
Correct the brake disc
deflection or replace the brake disc.
Refer to “CHECKING THE FRONT BRAKE
DISC” on page 4-18.
4. Measure:
• Brake disc thickness
Measure the brake disc thickness at a few dif-
ferent locations.
Out of specification
→
Replace.
Refer to “CHECKING THE FRONT BRAKE
DISC” on page 4-18.
5. Adjust:
• Brake disc deflection
Refer to “CHECKING THE FRONT BRAKE
DISC” on page 4-18.
6. Install:
• Rear wheel
Refer to “REAR WHEEL” on page 4-12.
REPLACING THE REAR BRAKE PADS

LEVEL” on page 3-19.
7. Check:
• Brake pedal operation
Soft or spongy feeling
→
