INTRODUCTION
WARNING
EWA14101
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.

Replace.
2. Measure:
• Brake disc deflection
Out of specification
→
Correct the brake disc
deflection or replace the brake disc.
a. Place the vehicle on a suitable stand so
that the front wheel is elevated.
b. Remove the brake caliper.
c. Hold the dial gauge at a right angle against
the brake disc surface.
d. Measure the deflection 1.5 mm (0.06 in)
below the edge of the brake disc.
3. Measure:
• Brake disc thickness
Measure the brake disc thickness at a few dif-
ferent locations.
Out of specification
→
Replace.
4. Adjust:
• Brake disc deflection
a. Remove the brake disc.
b. Rotate the brake disc by two bolt holes.
c. Install the brake disc.
NOTICE

brought within specification, replace the
brake disc.
