3. If the resultant distance is less than
specified, take the snowmobile to an
authorized Yamaha Snowmobile
dealer for service. If not under war-
ranty, this service is at the discretion
and expense of the snowmobile owner.
Bleeding Brake System
If the brake lever feels spongy when
applied, the brake system may need to be
bled. To bleed the brake, use the follow-
ing procedure:
NOTE: The brake system may be
bled by the snowmobile owner if
qualified to do so. If the owner
does not feel qualified, take the
snowmobile to an authorized
Yamaha Snowmobile dealer for this
service. This service is at the dis-
cretion and expense of the snow-
mobile owner.
1. Remove the reservoir cover and (if
necessary) fill the reservoir to the
high brake fluid mark with Yamaha
approved DOT 4 brake fluid.
2. Slide a piece of flexible tubing over
the ball of the bleeder valve and
direct the other end into a container.

3. Slowly compress the brake lever
until maximum pressure is attained;
then hold the lever in the com-
pressed position to maintain pres-
sure. Open the bleeder valve to
release the fluid and air. When the
fluid stops, close the bleeder valve;
then release the brake lever.
4. Repeat step 3 until the brake fluid
flows free of air bubbles.
NOTE: It may be necessary to
refill the reservoir during the bleed-
ing process. Never allow the brake
fluid to go below the low brake
fluid mark in the reservoir.
5. When the brake fluid is free of all air
and the brake lever feels firm when
compressed, fill the reservoir to the
high brake fluid mark; then install and
secure the cover. Remove the tube
from the bleeder valve.
Checking/Changing Brake Pads
The condition of the brake pads must be
checked daily and changed if worn or
damaged. To check and change the brake
pads, use the following procedure:
NOTE: The brake pads may be
changed by the snowmobile owner
if qualified to do so. If the owner
does not feel qualified, take the
snowmobile to an authorized
Yamaha Snowmobile dealer for this
service. This service is at the dis-
cretion and expense of the snow-
mobile owner.
NOTE: When installing new brake
pads, always install them as a set.
Never install just one pad or use
brake pads which have been used
in another snowmobile.
WARNING
Do not operate the snowmobile if
the compressed distance between
the brake lever and the handlebar is
less than 2.54 cm (1 in.). Brake loss
may occur. Brake loss can result in
severe personal injury.
CAUTION
Brake fluid is highly corrosive. Do
not spill brake fluid on any surface
of the snowmobile.
WARNING
Use only Yamaha approved DOT 4
brake fluid. Any substitute may
result in a loss of brakes.
