8If your ATV is traversing a sloping surface:
Be sure to ride with your weight positioned
towards the uphill side of the ATV to maintain
proper balance. If the ATV starts to tip, steer
down the hill (if there are no obstacles in your
way) to regain balance. If you discover that
the ATV is going to tip over, dismount on the
uphill side. (See pages 7-63–7-65.)
8If your ATV encounters shallow water:
Ride slowly and carefully through slow mov-
ing water, watching for obstacles. Be sure to
let water drain from the ATV and CHECK
YOUR BRAKES FOR PROPER OPERATION
when you come out of the water. Do not con-
tinue to ride your ATV until you have regained
adequate braking ability. (See pages 7-67–
7-69.)

8Recommended brake fluid: DOT 4
8Brake fluid replacement:
9When disassembling the master cylinder or caliper cylinder, replace the brake fluid. Normally
check the brake fluid level and add fluid as required.
9On the inner parts of the master cylinder and caliper cylinder, replace the oil seals every two
years.
9Replace the brake hoses every four years, or if cracked or damaged.

Brake fluid level check
Insufficient brake fluid may let air enter the
brake system, possibly causing the brakes to
become ineffective.
Before riding, check that the brake fluid is above
the minimum level mark and replenish if neces-
sary. A low brake fluid level may indicate worn
brake pads and/or brake system leakage. If the
brake fluid level is low, be sure to check the
brake pads for wear and the brake system for
leakage.
Observe these precautions:
8When checking the fluid level, make sure
the top of the brake fluid reservoir is level by
turning the handlebars.
8Use only the designated quality brake fluid.
Otherwise, the rubber seals may deterio-
rate, causing leakage and poor brake per-
formance.

8Refill with the same type of brake fluid.
Mixing fluids may result in a harmful chemi-
cal reaction and lead to poor brake perfor-
mance.
8Be careful that water does not enter the
brake fluid reservoir when refilling. Water
will significantly lower the boiling point of the
fluid and may result in vapor lock.
8Brake fluid may deteriorate painted surfaces
or plastic parts. Always clean up spilled fluid
immediately.
8Have a Yamaha dealer check the cause if
the brake fluid level goes down.
EBU01186
Brake fluid replacement
Complete fluid replacement should be done only
by trained Yamaha service personnel. Have a
Yamaha dealer replace the following compo-
nents during periodic maintenance or when they
are damaged or leaking.
8Replace the oil seals every two years.
8Replace the brake hoses every four years.

Front brake pad inspection
Inspect the brake pads for damage and wear. If
the thickness is less than the specified value,
have a Yamaha dealer replace the pads.
NOTE:
The wheels need to be removed to inspect the
brake pads. See page 8-87 for removal proce-
dures.
EBU00314
Rear brake pad inspection
A wear indicator is provided on each brake pad.
This indicator allows checking of brake pad wear
without disassembling the brake. Apply the
brake and inspect the wear indicator. If the
brake pads are worn to the wear limit, have a
Yamaha dealer replace the pads.

Front brake lever free play
The front brake lever should have a free play of
zero mm at the lever end. If not, have a Yamaha
dealer adjust it.
w
Operating with improperly serviced or
adjusted brakes could cause loss of braking
ability which could lead to an accident.
After servicing:
8Make sure the brakes operate smoothly
and that the free play is correct.
8Make sure the brakes do not drag.
8Make sure the brakes are not spongy. All
air must be bled from the brake system.
Replacement of brake components requires
professional knowledge. These procedures
should be performed by a Yamaha dealer.
