Brake fluid leakage (front brake)
Check to see if any brake fluid is leaking out of the
hose, joint or brake fluid reservoir of the front
brake. Apply the brake firmly for one minute. If the
lever moves slowly inward, there may be a leak in
the brake system. If there is any leakage, 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 performance, in-
spect the brake pads and shoes for wear. (See
page 8-81.)

Front brake pad check
Check the brake pads for damage and wear. If a
brake pad thickness is less than 1 mm, have a
Yamaha dealer replace the pads as a set.NOTE:_ The wheels need to be removed to check the
brake pads. (See pages 8-103–8-105 for removal
and installation procedures.) _

Rear brake shoe inspection
A wear indicator is provided on the rear brake.
This indicator allows checking of brake shoe wear
without disassembling the brake. Apply the rear
brake and check the position of the indicator. If the
indicator reaches the wear limit line, ask a
Yamaha dealer to replace shoes as a set.

Brake fluid level check
Insufficient brake fluid may let air enter the brake
system, possibly causing the brakes to become in-
effective.
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:

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


Use only the designated quality brake fluid, oth-
erwise, the rubber seals may deteriorate, caus-
ing leakage and poor brake performance.
Recommended brake fluid: DOT 4
