Refer to Important Safety Precautions on page 33.
B
oth 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 125), 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.
