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.1Front

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.
NOTE:
To access the rear brake fluid reservoir cap,
remove the seat (see page 4-29), remove the
cowling bolt and quick fastener, and then pull
the cowling slightly outward as shown.

Observe these precautions:
8When checking the brake fluid level, make
sure the top of the brake fluid reservoir is
level.
8Use only the designated quality brake fluid,
otherwise, the rubber seals may deteriorate,
causing leakage and poor brake performance.
8Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reac-
tion and lead to poor brake performance.
8Be 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.
8Brake fluid may deteriorate painted surfaces
or plastic parts. Always clean up spilled fluid
immediately.
8Have a Yamaha dealer check the cause if the
brake fluid level goes down.

Front brake lever free play
The front brake lever should have a free play of
zero mm at the lever end. If not, have a Yamaha
dealer check the brake system.
w
Operating with improperly serviced or
adjusted brakes could cause loss of braking
ability which could lead to an accident.
After servicing:
8Make sure the brakes operate smoothly
and that the free play is correct.
8Make sure the brakes do not drag.
8Make sure the brakes are not spongy. 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.

1. Release the parking brake by moving the
parking brake lever to the right.
2. Loosen the locknut on the brake cable.
3. Turn the adjusting nut on the brake cable
in direction ato increase the cable length
or in direction bto decrease the cable
length.

Operating with improperly adjusted brakes
could cause the brakes to malfunction,
resulting in reduced braking performance.
This could increase the chance of a collision
or accident. After adjusting the parking
brake, block the rear of the machine off the
ground and spin the rear wheels. Check to
make sure there is no brake drag. If brake
drag is noticed, perform the adjustment
again.
