2005 YAMAHA YFM660R brake pads

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, have a Yamaha dealer inspect the brake sys-
tem.
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 for wear. (See page 8-67.)
WARNING
_ Always check the brakes at the start of every
ride. Do not ride the ATV if you find any prob-
lem with the brakes or you could lose braking
ability, which could lead to an accident. If a
problem cannot be corrected by the adjust-
ment procedures provided in this manual,
have a Yamaha dealer check for the cause. _

Front and rear 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 grooves are almost in contact with
the disc plate, ask a Yamaha dealer to replace the
brake pads as a set.

Brake fluid level inspection
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.
