       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-             ▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲▲

CHECKING THE FRONT BRAKE DISCS
The following procedure applies to both brake
discs.
1. Remove:                                                   5. Adjust:

                                                             a. Remove the brake disc.
2. Check:
                                                             b. Rotate the brake disc by one bolt hole.

   Damage/galling → Replace.
3. Measure:                                                             Brake disc bolt

a. Place the vehicle on a suitable stand so that
   the front wheel is elevated.
b. Before measuring the front brake disc deflec-
   tion, turn the handlebar 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.
