FRONT BRAKE
• Fill the reservoir with brake fluid to the top of the inspection
window. Place the reservoir cap to prevent dirt from entering.
• Attach a hose to the air bleeder valve and insert the free end
of the hose into a receptacle.
• Squeeze and release the brake lever several times in rapid
succession and squeeze the lever fully without releasing it.
Loosen the air bleeder valve by turning it a quarter of a turn so
that the brake fluid runs into the receptacle. This will remove
the tension of the brake lever causing it to touch the handle-
bar grip. Then, close the air bleeder valve, pump and squeeze
the lever, and open the valve. Repeat this process until fluid
flowing into the receptacle no longer contains air bubbles.
NOTE:
While bleeding the brake system, replenish the brake fluid in the
reservoir as necessary. Make sure that there is always some
fluid visible in the reservoir.
• Close the air bleeder valve and disconnect the hose. Fill the
reservoir with brake fluid to the top of the inspection window.
 Specification and classification: DOT 4
 Air bleeder valve: 7.5 N·m (0.75 kgf-m)

* The brake system of this motorcycle is filled with a
glycol-based brake fluid. Do not use or mix different
types of fluid such as silicone-based and petro-
leum-based fluids. Do not use any brake fluid taken
from old, used or unsealed containers. Never re-use
brake fluid left over from the last servicing or stored
for a long period of time.
* Brake fluid, if it leaks, will interfere with safe running
and immediately discolor painted surfaces. Check
the brake hoses and hose joints for cracks and fluid
leakage before riding.
REAR BRAKE
• Bleed air from the rear brake system in the same manner as
front brake.
 Air bleeder valve: 7.5 N·m (0.75 kgf-m)
NOTE:
The only difference of bleeding operation from the front brake is
that the rear master cylinder is actuated by the pedal.
PERIODIC MAINTENANCE 2-25
