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.)

Front and rear brake pad inspection
Each brake pad is provided with a wear indica-
tor. The indicators allow checking of brake pad
wear without disassembling the brake. Apply the
brake and inspect the wear indicators. If they
are ALMOST in contact with the disc plate, ask
a Yamaha dealer to replace the pads.

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.
