CHECKING THE BRAKE DISCS
The following procedure applies to all of the
brake discs.
1. Check:
Sbrake discs
Damage/galling ! Replace.
2. Measure:
Sbrake disc deflection
Out of specification ! Correct the brake disc
deflection or replace the brake disc.
Brake disc deflection limit
(maximum)
Front: 0.1 mm (0.004 in)
Rear: 0.15 mm (0.006 in)
a. Place the motorcycle on a suitable stand so
that the wheel is elevated.
b. Before measuring the front brake disc deflec-
tion, turn the handlebars to the left or right to
ensure that the front wheel is stationary.
c. Remove the brake caliper.
d. Hold the dial gauge at a right angle against
the brake disc surface.
e. Measure the deflection 2 X 3 mm (0.08 X
0.12 in) below the edge of the brake disc.
3. Measure:
Sbrake disc thickness
Measure the brake disc thickness at a few
different locations.
Out of specification ! Replace.
Brake disc thickness limit
(minimum)
Front: 4.5 mm (0.18 in)
Rear: 4.5 mm (0.18 in)
4. Adjust:
Sbrake disc deflection
a. Remove the brake disc.
b. Rotate the brake disc by one bolt hole.
c. Install the brake disc.
Tighten the brake disc bolts in stages and in a
crisscross pattern.
