5Brake fluid leakage (front brake)
Check to see if any brake fluid is leaking out of the
hose, joint or brake fluid reservoir of the front
brake. Apply the brake 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 checked 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 performance,
check the brake pads and friction plates for wear.
(See page 8-39.)
EBU19762Throttle leverCheck the operation of the throttle lever. It must
open smoothly and spring back to the idle position
when released. Have a Yamaha dealer correct if
necessary.EBU38060TiresCheck and adjust the tire pressure before each
ride. Check tires for wear and damage. Tire pressure
A low-pressure tire gauge is included as standard
equipment. Make two measurements of the tire
pressure and use the second reading. Dust or dirt
in the gauge could cause the first reading to be in-
correct.
Tire pressure must be checked and set when the
tires are cold. The tire pressure should be the
same on both sides, and must be adjusted ac-
cording to vehicle loading conditions. Set the tire
pressure as specified below.
WARNING! Opera-
tion of this vehicle with improper tire pressure
may cause severe injury or death from loss of
1. Low-pressure tire gauge
2. Tire air valve

For odometer or hour meter-equipped vehicles, follow the month maintenance interval if the ATV isn’t
ridden for the stated distance or engine operating hours.

EBU28414Checking the front brake pads and rear
brake friction platesThe front brake pads and the rear brake friction
plates must be checked for wear at the intervals
specified in the periodic maintenance and lubrica-
tion chart.TIPThis ATV is equipped with a wet, multiple-disc
type rear brake, which is located inside of the final
gear case. EBU24174Front brake padsCheck each front brake pad for damage and mea-
sure the lining thickness. If a brake pad is dam-
aged or if the lining thickness reaches the
specified limit, have a Yamaha dealer replace the
brake pads as a set.
TIPThe wheels need to be removed to check the
brake pads. (See page 8-63.) EBU30321Rear brake friction plates
The rear brake friction plates must be checked
and, if necessary, replaced by a Yamaha dealer at
the intervals specified in the periodic maintenance
and lubrication chart.EBU29844Checking the brake fluid levelBefore riding, check that the brake fluid is above
the minimum level mark. Replenish the brake fluid
if necessary.
1. Lining thickness
Brake pad lining thickness limit:
1.0 mm (0.04 in)

TIPStraighten the handlebars for an accurate reading. NOTICEECB01161Brake fluid may damage painted surfaces or
plastic parts. Always clean up spilled fluid im-
mediately.
As the brake pads wear, it is normal for the brake
fluid level to gradually go down. A low brake fluid
level may indicate worn brake pads or brake sys-
tem leakage. Therefore, be sure to check the
brake pads for wear and the brake system for
leakage. If the brake fluid level suddenly goes
down, have a Yamaha dealer the brake system
before further riding.
WARNING
EWB02721Improper maintenance can result in loss of
braking ability. Observe these precautions:
Insufficient brake fluid may allow air to enter
the brake system, reducing braking perfor-
mance.
Clean the filler cap before removing. Use
only DOT 4 brake fluid from a sealed contain-
er.
Use only the specified brake fluid; otherwise,
the rubber seals may deteriorate, causing
leakage.
Refill with the same type of brake fluid. Add-
ing a brake fluid other than DOT 4 may result
in a harmful chemical reaction.
