Brake fluid leakage

Check to see if any brake fluid is leaking out of
the pipe joints or brake fluid reservoirs. Apply
the brakes firmly for one minute. If the lever
moves slowly inward, there may be a leak in
the brake system. If there is any leakage, the
brake system should be inspected by a
Yamaha dealer.

Brake operation

Test the brakes at slow speed after starting
out to make sure they are working properly. If
the brakes do not provide proper braking per-
formance, inspect the brake pads for wear.
(See pages 8-39–8-40.)

WARNING

POTENTIAL HAZARD 
Riding with improperly operating
brakes. 
WHAT CAN HAPPEN 
You could lose braking ability, which
could lead to an accident. 
HOW TO AVOID THE HAZARD 
Always check the brakes at the start of
every ride. Do not ride the ATV if you
find any problem with the brakes. If a
problem cannot be corrected by the ad-
justment procedures provided in this
manual, have a Yamaha dealer check for
the cause.
