●
A soft, spongy feeling in the brake lever
indicates a failure in the brake system.
●
Do not operate the snowmobile if you
find any problems in the brake system.
You could lose braking ability, which
could lead to an accident. Ask a Yamaha
dealer to inspect and repair the brake

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.)
