As the brake pads wear, it is normal for the
brake fluid level to gradually go down. A low
brake fluid level may indicate worn brake
pads and/or brake system leakage; therefore,
be sure to check the brake pads for wear and
the brake system for leakage. If the brake fluid
level goes down suddenly, have a Yamaha
dealer check and repair the vehicle before
any further operation.EBU32520Brake fluid replacementComplete fluid replacement should be done
only by trained Yamaha service personnel.
Have a Yamaha dealer replace the following
components during pe riodic maintenance or
when they are damaged or leaking.
Replace the oil seals every two years.
Replace the brake hoses every four years.
EBU32530Checking the brake pedalHave a Yamaha dealer check the brakes at
the intervals specified in the periodic mainte-
nance and lubrication chart. There should be
no free play in the brake pedal. The brakes
should operate smoothly and there should be
no brake drag. If the brakes feel soft or
spongy, this could indicate air in the brake
system. Have a Yamaha dealer check the
brake system if necessary.1. Brake pedal

EBU33710Parking brakePull the parking brake lever rearward com-
pletely. If the parking brake lever clicks eight
times or more, have a Yamaha dealer adjust
the parking brake because the braking force
of the parking brake is weak. In addition, have
a Yamaha dealer check and adjust the park-
ing brake at the intervals specified in the peri-
odic maintenance and lubrication chart.EBU32550Brake light switch adjustmentThe brake light switch, which is activated by
the brake pedal, is properly adjusted when
the brake light comes on just before braking
takes effect. If necessary, adjust the brake
light switch as follows.
Turn the adjusting nut while holding the brake
light switch in place. To make the brake light
come on earlier, turn the adjusting nut in di-
rection (a). To make the brake light come on
later, turn the adjusting nut in direction (b).
