EBU00477Front and rear brakes
1. Brake levers and brake pedal
Check for correct free play in the brake
levers and brake pedal. If the free play is
incorrect, adjust it. (See pages 8-43 ~
8-49.)
Check operation of the levers and pedal.
They should move smoothly and there
should be a firm feeling when the brake is
applied. If not, have the machine inspected
by a Yamaha dealer.
2. Brake operation
Test the brakes at slow speed after starting
out to make sure they are working proper-
ly. If the brakes do not provide proper brak-
ing performance, inspect the brakes for
wear. (See page 8-41.)

dent. If a problem cannot be corrected by the
adjustment procedures provided in this man-
ual, have the ATV inspected by a Yamaha
dealer.

EBU00208To decelerate:
When slowing down or stopping, release the
throttle and apply the brakes smoothly and
evenly. As you slow down, shift to a lower gear.
Be sure that the engine has sufficiently slowed
before engaging a lower gear. Improper use of
the brakes or shifting can cause the tires to lose
traction, reducing control and increasing the
possibility of an accident.wMake sure the engine has sufficiently slowed
before shifting to a lower gear. Engaging a
lower gear when the engine speed is too
high could make the wheels stop rotating.
This could cause loss of control, an accident
and injury. It could also cause engine or
drive train damage.

EBU00220Parking on a slopewAvoid parking on hills or other inclines.
Parking on a hill or other incline could cause
the ATV to roll out of control, increasing the
chance of an accident. If you must park on
an incline, put the machine in low gear, apply
the parking brake, and block the front and
rear wheels with rocks or other objects.
Do not park the ATV at all on hills that are so
steep you could not walk up them easily.1. Bring the machine to a stop by applying
the brakes in low gear.
2. Stop the engine.
3. With the rear brake lever and pedal
applied, apply the parking brake and slowly
release the rear brake pedal.
