The brake fluid reservoir is located under the
hood. (See pages 8-17–8-19 for hood opening
and closing procedures.)
Observe these precautions:

When checking the fluid level, make sure the
top of the brake fluid reservoir is level.


Use only the recommended quality brake fluid.
Otherwise, the rubber seals may deteriorate,
causing leakage and poor braking perfor-
mance.


Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reaction
and lead to poor braking performance.


Be careful that water does not enter the brake
fluid reservoir when refilling. Water will signifi-
cantly lower the boiling point of the fluid and
may result in vapor lock. Recommended brake fluid: DOT 4

Brake fluid may deteriorate painted surfaces or
plastic parts. Always clean up spilled fluid im-
mediately.


Have a Yamaha dealer inspect the brake sys-
tem if the brake fluid level goes down.

Brake 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.
