Test the brake at a low speed when starting
out to make sure that it is working properly. If
the brake does not provide proper braking
performance, inspect the brake for wear or
brake fluid leakage. (See the following section
for more details.)
Checking the brake pads
Check the brake pads for wear.
If the brake pads reach the wear limit, ask a
Yamaha dealer to replace them.
