Front and rear brakes
Brake lever and brake pedal
8Check that there is no free play in the brake
lever. If there is free play, have a Yamaha
dealer adjust it. Check for correct brake pedal
height. If the pedal height is incorrect, have a
Yamaha dealer adjust it. (See pages 8-81–
8-83.)
8Check the operation of the lever and pedal.
They should move smoothly and there should
be a firm feeling when the brakes are applied.
If not, have the machine inspected by a Yama-
ha dealer.
Brake fluid level
Check the brake fluid level.
Add fluid if necessary. (See pages 8-75–8-79.)
Recommended brake fluid: DOT 4

Brake fluid leakage
Check to see if any brake fluid is leaking out of
the pipe joints or brake fluid reservoirs. Apply the
brakes firmly for one minute. If there is any leak-
age, the brake system should be inspected by a
Yamaha dealer.
Brake operation
Test the brakes at slow speed after starting out
to make sure they are working properly. If the
brakes do not provide proper braking perfor-
mance, inspect the brake pads for wear. (See
page 8-73.)

NOTE:
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 the 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 brake fluid level, make
sure the top of the brake fluid reservoir is
level.
8Use only the designated quality brake fluid,
otherwise, the rubber seals may deteriorate,
causing leakage and poor brake performance.

8Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reac-
tion and lead to poor brake performance.
8Be 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.
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.
