EBU27472Checking the front and rear brake padsThe front and rear brake pads must be checked
for wear at the intervals specified in the periodic
maintenance chart. Each brake pad is provided
with a wear indicator groove, which allows you to
check the brake pad wear without having to disas-
semble the brake. If a brake pad has worn to the
point that the wear indicator groove has almost
disappeared, have a Yamaha dealer replace the
brake pads as a set.TIPThe wheels need to be removed to check the
brake pads. (See page 9-61.)

the minimum level mark. Replenish the brake fluid
if necessary.TIPStraighten the handlebars for an accurate reading. Front brakeRear brake
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

leakage. If the brake fluid level suddenly goes
down, have a Yamaha dealer check the brake sys-
tem 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.
 Be careful that water does not enter the
brake fluid reservoir when refilling. Water will
significantly lower the boiling point of the flu-
id and may result in vapor lock.
EBU24294Changing the brake fluidHave a Yamaha dealer change the brake fluid at
the intervals specified in the periodic maintenance
chart. In addition, have the oil seals of the master
cylinders and calipers as well as the brake hoses
replaced at the intervals listed below or whenever
they are damaged or leaking.
Oil seals: Replace every two years.
 Brake hoses: Replace every four years.

EBU24905Checking and lubricating the cablesThe operation and the condition of all control ca-
bles should be checked before each ride, and the
cables and cable ends should be lubricated if nec-
essary. If a cable is damaged or does not move
smoothly, have a Yamaha dealer check or replace
it.
WARNING
EWB02582Inspect cables frequently and replace if
damaged. Corrosion can result when the ca-
ble sheaths become damaged, and cables
can also become frayed or kinked, which
could restrict the operation of controls and
lead to an accident or injury.
 Always make sure all control cables work
smoothly before you begin riding in cold
weather. If the control cables are frozen or
do not work smoothly, you could be unable
to control the ATV, which could lead to an
accident or collision. EBU24913Checking and lubricating the front and
rear brake leversThe operation of the front and rear brake levers
should be checked before each ride, and the lever
pivots should be lubricated if necessary.
