 WARNING
Riding with worn brake pads will
reduce braking performance and will
increase your chance of having an
accident.
Inspect brake pad wear before each
use. Ask your SUZUKI dealer or a
qualified mechanic to replace brake
pads if any pad is worn to the limit.
 WARNING
Failure to extend brake pads after
repair or replacement can cause
poor braking performance and may
result in an accident.
Before riding, "pump" the brake
lever/pedal repeatedly until brake
pads are pressed against the brake
disk and proper lever/pedal stroke
and firm feel are restored.
NOTE: Do not squeeze/depress the
brake lever/pedal when the pads are
not in their positions. It is difficult to
push the pistons back into position.
