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
leakage, have a Yamaha dealer inspect the
brake system.
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 8-81–8-83.)

Front brake pad inspection
Each brake pad is provided with a wear indicator
groove. The indicator grooves allow checking of
brake pad wear without disassembling the
brake. Apply the brake and inspect the wear
indicator grooves. If a brake pad is worn to the
point that the wear indicator groove is almost in
contact with the disc plate, ask a Yamaha dealer
to replace the brake pads as a set.
NOTE:
The wheels need to be removed to inspect the
brake pads. (See page 8-125 for wheel removal
and installation procedures.)

Brake fluid level inspection
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.
