Front and rear brakes
1. Brake levers and brake pedal
Check for correct free play in the rear brake
lever and that there is no free play in the front
brake lever. If the free play is incorrect, adjust
it. (See pages 8-99 ~ 8-103.)
Check the operation of the levers and pedal.
They should move smoothly and there
should be a firm feeling when the brakes are
applied. If not, have the machine inspected
by a Yamaha dealer.
2. Brake fluid level
Check the brake fluid level.
Add fluid if necessary. (See pages 8-93 ~
8-97.)

Check to see if any brake fluid is leaking out
of the pipe joints or master cylinder. Apply the
brakes firmly for one minute. If there is any
leaking, have the machine inspected by a
Yamaha dealer. Recommended brake fluid: DOT 4

lem with the brakes or you could lose braking
ability, which could lead to an accident. If a
problem cannot be corrected by the adjust-
ment procedures provided in this manual,
have the ATV inspected by a Yamaha dealer.
