Parking / Rear Brake Light Switch Inspection

Inspect the parking/rear brake light switch in the
following procedures:
1) Remove the left inner fender. Refer to "Front Side
Exterior Parts Removal and Installation in Section
9D (Page 9D-6)".
2) Disconnect the parking/rear brake light switch lead
wire coupler (1).

3) Inspect the parking/rear brake light switch for
continuity with a tester. If any abnormality is found,
replace the parking/rear brake lever assembly with a
new one. Refer to "Handlebars Removal and
Installation in Section 6B (Page 6B-3)".

Air Bleeding from Front Brake Fluid Circuit

Air trapped in the brake fluid circuit acts like a cushion to
absorb a large proportion of the pressure developed by
the master cylinder and thus interferes with the full
braking performance of the brake caliper. The presence
of air is indicated by "sponginess" of the brake lever and
also by lack of braking force. Considering the danger to
which such trapped air exposes the machine and rider, it
is essential that after remounting the brake and restoring
the brake system to the normal condition, the brake fluid
circuit be purged of air in the following manner:
CAUTION
!
• Make sure that the vehicle is supported
securely.
• Handle brake fluid with care: the fluid
reacts chemically with paint, plastic,
rubber materials, etc.
1) Fill the master cylinder reservoir to the top of the
inspection window. Place the reservoir cap to
prevent dirt from entering.
2) Attach a hose to the air bleeder valve, and insert the
free end of the hose into a receptacle.
3) Squeeze and release the brake lever several times
in rapid succession and squeeze the lever fully
without releasing it.
