Brakes
Replacement of brake components requires
professional knowledge. Brake service should
be performed by a Yamaha dealer.
WARNING
Operating with improperly serviced or ad-
justed brakes could lead to a loss in brak-
ing ability and an accident.5B410019Checking the front and rear brake pads
Each brake pad is provided with wear indica-
tor grooves, which allow you to check the
brake pad wear without having to disassem-
ble the brake. To check the brake pad wear,
check the wear indicator grooves. If a brake
pad has worn to the point that the wear indica-
tor grooves have almost disappeared, have a
Yamaha dealer replace the brake pads as a
set. The wheels need to be removed to check the
brake pads. (See pages 8-44–8-46 for wheel
removal and installation procedures.)

5B410020Checking the parking brake pads
Each brake pad is provided with two wear in-
dicator grooves, which allow you to check the
brake pad wear without having to disassem-
ble the brake. To check the brake pad wear,
check the wear indicator grooves. If a brake
pad has worn to a wear indicator groove, have
a Yamaha dealer replace the brake pads as a
set.1. Brake pad wear indicator groove
EVU00850Checking the brake fluid level
The brake fluid reservoir is located under the
hood. (See pages 8-7–8-8 for hood opening
and closing procedures.)
Before riding, check that the brake fluid is
above the minimum level mark. Check the
brake fluid level with the top of the reservoir
level. Replenish the brake fluid if necessary.1. Minimum level mark

Specified brake fluid: DOT 4

WARNING
Improper maintenance can result in loss of
braking ability. Observe these precautions:●
Insufficient brake fluid may allow air to
enter the brake system, reducing brak-
ing performance.
●
Clean the filler cap before removing.
Use only DOT 4 brake fluid from a
sealed container.
●
Use only the specified brake fluid; oth-
erwise, the rubber seals may deterio-
rate, 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 does not enter
the brake fluid reservoir when refilling.
Water will significantly lower the boil-
ing point of the fluid and may result in
vapor lock.
NOTICEBrake 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 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 suddenly, have a Yamaha
dealer check the cause before further riding.EVU00860Brake fluid replacement
Complete 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 hoses every four years.
