Use only the recommended quality brake fluid,
otherwise the rubber seals may deteriorate,
causing leakage and poor braking performance.
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.
Brake fluid may deteriorate painted surfaces or
plastic parts. Always clean up spilled fluid imme-
diately.
As the brake pads wear, it is normal for the brake
fluid level to gradually go down. However, if the
brake fluid level goes down suddenly, have a
Yamaha dealer check the cause.EBU24280Changing the brake fluid Have a Yamaha dealer change the brake fluid at
the intervals specified in the NOTE after the peri-
odic maintenance and lubrication chart. In addi-tion, 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.EBU24390Checking the front brake lever free play The brake lever free play must be checked at the
intervals specified in the periodic maintenance and
lubrication chart. The brake lever should have a
free play of zero mm (zero in) as shown. If the free
play is incorrect, have a Yamaha dealer check the
brake system. Recommended brake fluid:

When adjusting the rear brake, be sure to adjust
both the brake pedal and the brake lever.
Before adjusting the brake lever and brake pedal
free play, check the rear brake friction plates forwear.

The brake pedal free play should measure 17.0–
20.0 mm (0.67–0.79 in). The brake lever free play
should measure 8.0–10.5 mm (0.31–0.41 in). If ei-
ther free play is incorrect, adjust it as follows.
