Rear brake pad check
Each brake pad is provided with wear indicator
grooves, which allow you to check the brake pad
wear without having to disassemble the brake. To
check the brake pad wear, check the wear indica-
tor grooves. If a brake pad has worn to the point
that the wear indicator grooves have almost disap-
peared, have a Yamaha dealer replace the brake
pads as a set.
EVU00850
Checking the brake fluid level
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.

The brake fluid reservoir is located under the
hood. (See pages 8-17–8-19 for hood opening
and closing procedures.)
Observe these precautions:

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


Use only the recommended quality brake fluid.
Otherwise, the rubber seals may deteriorate,
causing leakage and poor braking perfor-
mance.


Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reaction
and lead to poor braking performance.


Be careful that water does not enter the brake
fluid reservoir when refilling. Water will signifi-
cantly lower the boiling point of the fluid and
may result in vapor lock. Recommended brake fluid: DOT 4

Brake fluid may deteriorate painted surfaces or
plastic parts. Always clean up spilled fluid im-
mediately.


Have a Yamaha dealer inspect the brake sys-
tem if the brake fluid level goes down.
EVU00860
Brake fluid replacement
Complete fluid replacement should be done only
by trained Yamaha service personnel. Have a
Yamaha dealer replace the following components
during periodic maintenance or when they are
damaged or leaking.

Replace the oil seals every two years.


Replace the brake hoses every four years.

EVU01480
Checking the brake pedal
Have a Yamaha dealer check the brakes at the in-
tervals specified in the periodic maintenance 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.
WARNING
Operating with improperly serviced or adjust-
ed brakes could cause loss of braking ability,
which could lead to an accident.
After servicing:

Make sure the brakes operate smoothly
and that the brake pedal position is cor-
rect.


Make sure the brakes do not drag.


All air must be bled from the brake system.
Replacement of brake components requires
professional knowledge. These procedures
should be performed by a Yamaha dealer.

dures.)
4. Check the parking brake lever free play. The
maximum free play is equal to one click of the
parking brake lever. If necessary, adjust the
free play as follows.NOTE:_ The parking brake lever must be released when
checking and adjusting the parking brake lever
free play. _

Brake light switch adjustment
The 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.
1. Open the hood. (See pages 8-17–8-19 for
hood opening and closing procedures.)
2. 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.
3. Close the hood.
