Servicing Your Honda 111
Brakes
Refer to Important Safety Precautions on page 23.
Both the front and rear brakes are the hydraulic
disc type. As the brake pads wear
, the brake fluid
level will drop. A leak in the system will also cause
the level to drop.
Frequently inspect the system to ensure there are
no fluid leaks. Periodically inspect the brake fluid
level and the brake pads for wear.
If the braking response of the front brake lever or
rear pedal feels unusual, check the brake pads. If
the brake pads are not worn beyond the
recommended limit (page 114), there is probably
air in the brake system.
Refer to an official Honda Service Manual or see
your dealer to have the air bled from the system.
1. Loosen the lock nut (1).
2. To position the front brake lever farther away
from the handgrip, turn the adjuster (2)

To position the front brake lever closer to the
handgrip, turn the adjuster counterclockwise.
3. While holding the adjuster, tighten the lock nut
to the specified torque:
4.4 lbf·ft (5.9 N·m, 0.6 kgf·m)
4. Apply silicone grease to the contacting areas of
the adjuster.
The rear brake pedal height should be
approximately level with the right footpeg.
