BRAKE SHOES WEAR
Refer to the Safety Precautions on page 55.
The rear brake is equipped with a brake
wear indicator.
When the brake is applied, an arrow (1)
attached to the brake arm (2) moves toward
a reference mark (3) on the brake panel (4).
If the arrow aligns with the reference mark
on full application of the brake, the brake
shoes must be replaced.
See your dealer for this service.
When the brake service is necessary, see
your dealer. Use only Honda Genuine Parts
or its equivalent.
