INTRODUCTION
WARNING
EWA14100
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 FRONT BRAKE DISCS
The following procedure applies to both brake
discs.
1. Remove:
• Front wheel
Refer to “FRONT WHEEL” on page 4-4.
2. Check:
• Brake disc
Damage/galling → Replace.
3. Measure:

tion, turn the handlebar to the left or right to
ensure that the front wheel is stationary.

d. Hold the dial gauge at a right angle against
the brake disc surface.
