Brake light switches
1. Rear brake light switch adjusting nut
2. Brake light switch
The brake light, which is activated by
the brake pedal and brake lever,
should come on just before braking
takes effect. If necessary, adjust the
rear brake light switch as follows, but
the front brake light switch should be
adjusted by a Yamaha dealer.
Turn the rear brake light switch adjus-
ting nut while holding the rear brake
light switch in place. To make the bra-
ke light come on earlier, turn the
adjusting nut in direction (a). To make
the brake light come on later, turn the
adjusting nut in direction (b).
EAU22392
Checking the front and rear
brake pads
The front and rear brake pads must
be checked for wear at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU22430
Front brake pads
1. Brake pad wear indicator groove
Each front brake pad is provided with
wear indicator grooves, which allow
you to check the brake pad wear wit-
hout having to disassemble the brake.
To check the brake pad wear, check
the wear indicator grooves. If a brake
pad has worn to the point that the
wear indicator grooves have almostdisappeared, have a Yamaha dealer
replace the brake pads as a set.
EAU22480
Rear brake pads
Each rear brake pad is provided with
a wear indicator groove, which allows
you to check the brake pad wear wit-
hout having to disassemble the brake.
Check the brake pad wear as follows.
1. Remove the brake caliper bolt, and then tilt the caliper forward to
inspect the wear indicator groo-
ve. If a brake pad has worn to the
point that the wear indicator gro-
ove has almost disappeared,
have a Yamaha dealer replace
the brake pads as a set.

EAU22580
Checking the brake fluid
level
Front brake
1. Minimum level mark
Rear brake
1. Minimum level mark
Insufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
Before riding, check that the brake
fluid is above the minimum level mark
and replenish if necessary. A low bra-
ke 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:
When checking the fluid level,
make sure that the top of the bra-
ke fluid reservoir is level.
Use only the recommended qua-
lity brake fluid, otherwise the rub-
ber seals may deteriorate, cau-
sing leakage and poor braking
performance.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performan-
ce.
