EBU24121Checking the front brake pads and rear
brake shoesThe front brake pads and the rear brake shoes
must be checked for wear at the intervals speci-
fied in the periodic maintenance and lubrication
chart.EBU24172Front brake pads
Check each front brake pad for damage and mea-
sure the lining thickness. If a brake pad is dam-
aged or if the lining thickness is less than 1.0 mm
(0.04 in), have a Yamaha dealer replace the brake
pads as a set.
TIPThe wheels need to be removed to check the
brake pads. (See page 8-46.) EBU24181Rear brake shoes
The rear brake is provided with a wear indicator,
which allows you to check the brake shoe wear
without having to disassemble the brake. To
check the brake shoe wear, check the position of
the wear indicator while applying the brake. If a1. Brake pad

Yamaha dealer replace the brake shoes as a set.
EBU29843Checking the brake fluid levelBefore riding, check that the brake fluid is above
the minimum level mark. Check the brake fluid lev-
el with the top of the reservoir level. Replenish the
brake fluid if necessary.
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.
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 and/or brake
system leakage; therefore, be sure to check the
brake pads for wear and the brake system for
leakage. If the brake fluid level goes down sud-
denly, have a Yamaha dealer check the cause be-
fore further riding.
EBU24283Changing the brake fluidHave a Yamaha dealer change the brake fluid at
the intervals specified in the periodic maintenance
and lubrication chart. In addition, have the oil seals
of the brake master cylinder 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.EBU24395Checking the front brake lever free
playThe brake lever free play must be checked at the
intervals specified in the periodic maintenance
and lubrication chart. The brake lever should have
no free play as shown. If there is free play, have a
Yamaha dealer check the brake system.

rear brake lever free play must be checked and, if
necessary, adjusted at the intervals specified in
the periodic maintenance and lubrication chart.TIPAlways perform this maintenance completely in
the following order whenever adjusting the rear
brake. 
Before adjusting the brake pedal and brake le-
ver free play, check the rear brake shoes for
wear.
Checking and adjusting the brake pedal height
The top of the brake pedal should be positioned
72.0–82.0 mm (2.83–3.23 in) above the footboard
bracket.
Check and adjust the brake pedal height as fol-
lows.
1. Remove the footboard by removing the bolts and nuts.

2. Check the brake pedal height.
If the brake pedal height is correct, skip steps
3–5.
3. Loosen the locknut. 4. Turn the adjusting bolt in or out until the brake
pedal height is within the specified limits.
5. Tighten the locknut.
6. Install the footboard by installing the bolts and nuts, and then tighten the bolts to the

incorrect, adjust it as follows. 1. Fully loosen the brake lever free play adjust-
ing nut on the brake cable at the rear wheel
hub.
2. Turn the brake pedal free play adjusting nut on the brake cable at the rear wheel hub in di-

EBU24231Axle bootsThe axle boots must be checked for damage at
the intervals specified in the periodic maintenance
and lubrication chart. Check the axle boots for
tears or damage. If any damage is found, have
them replaced by a Yamaha dealer.EBU29882Brake light switchesThe brake light, which is activated by the brake
pedal and brake levers, should come on just be-
fore braking takes effect.The rear brake light switch for the brake pedal can
be adjusted as follows, but the other brake light
switches should be adjusted by a Yamaha dealer.
Turn the rear brake light switch adjusting nut while
holding the brake light switch in place. To make
the brake light come on earlier, turn the adjusting
nut in direction (a). To make the brake light come
on later, turn the adjusting nut in direction (b).

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.
EBU28712Checking 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.

Recommended lubricant:
Yamaha cable lubricant or other suitable cable lubricantRecommended lubricants: Front brake lever:Silicone grease
Rear brake lever: Lithium-soap-based grease
