WARNING
EWB03910Improper maintenance can result in loss of
braking ability or clutch operation. Ob-
serve these precautions:
Insufficient brake or clutch fluid may al-
low air to enter the brake or clutch sys-
tem, reducing braking or clutch
performance.
 Clean the filler caps before removing.
Use only DOT 4 brake fluid from a sealed
container.
 Use only the specified brake fluid; other-
wise, the rubber seals may deteriorate,
causing leakage.
 Refill with the same type of brake fluid.
Adding a brake fluid other than DOT 4
may result in a harmful chemical reac-
tion. 
Be careful that water or dust does not
enter the brake or clutch fluid reservoir
when refilling. Water will significantly
lower the boiling point of the fluid and
may result in vapor lock.
NOTICEECB01161Brake fluid may damage painted surfaces
or plastic parts. Always clean up spilled
fluid immediately. 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 system leakage; therefore, be
sure to check the brake pads for wear and the
brake system for leakage. A low clutch fluid
level may indicate clutch system leakage;
therefore, be sure to check the clutch system
for leakage. If the brake or clutch fluid level
goes down suddenly, have a Yamaha dealer
check and repair the vehicle before any fur-
ther operation.

EBU35170Brake and clutch fluid replacementComplete fluid replacement should be done
only by trained Yamaha service personnel.
Have a Yamaha dealer replace the following
components during periodic maintenance or
when they are damaged or leaking.
Replace the oil seals every two years.
 Replace the brake and clutch hoses every
four years.EBU35182Checking the clutch pedalThe clutch pedal should operate smoothly
and spring back to position when released.
When depressed, it should offer resistance
before reaching the floorboard. If the pedal
offers little resistance when depressed, or if
the transmission grinds gears when shifting,
have a Yamaha dealer check the vehicle.
TIPDon’t forget to have your Yamaha dealer
check the clutch and transmission as a whole
at the intervals specified in the periodic main-
tenance chart. EBU32531Checking the brake pedalHave a Yamaha dealer check the brakes at
the intervals specified in the periodic mainte-
nance chart. There should be no free play in1. Clutch pedal
