FRONT BRAKE
EAS30168
INTRODUCTION
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.
1. Check:
• Front brake disc

Out of specification Correct the brake disc
runout or replace the brake disc.
a. Place the vehicle on the centerstand 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 runout 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 runout
a. Remove the brake disc.
b. Rotate the brake disc by one bolt hole.
c. Install the brake disc.
NOTICE

Tighten the brake disc bolts in stages and in a
crisscross pattern.
d. Measure the brake disc runout.

steps until the brake disc runout is within
specification.
f. If the brake disc runout cannot be brought
within specification, replace the brake disc.
