Rear Brake Light Switch Inspection
Inspect the rear brake light switch in the following
procedures:
1) Lift and support the fuel tank. Refer to "Fuel Tank
Removal and Installation" in Section 1G (Page 1G-
9).
2) Disconnect the rear brake light switch lead wire
coupler (1).
3) Inspect the rear brake light switch for continuity with
the tester.
If any abnormality is found, replace the rear brake
light switch with a new one.

Rear Brake Light Switch Inspection and
Adjustment
Check the rear brake light switch so that the brake light
will come on just before pressure is felt when the brake
pedal is depressed. If the brake light switch adjustment
is necessary, turn the adjuster nut (1) in or out while
holding the brake pedal.

Brake Fluid Level Check

Refer to "Brake System Inspection" in Section 0B
(Page 0B-16).

Brake Hose Inspection

Refer to "Brake System Inspection" in Section 0B
(Page 0B-16).

Air Bleeding from 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
!
Handle brake fluid with care: the fluid reacts
chemically with paint, plastic, rubber
materials, etc.
