CAUTION
An incorrectly adjusted brake pedal may
force brake pads to rub against the disk at
all times, causing damage to the pads and
disk.
Follow the steps in this section to adjust
the brake pedal properly.
Rear Brake Light Switch
The rear brake light switch is located by
the brake pedal pivot. To adjust the
brake light switch, turn the screw 1
