2. If the brake fluid is below the high
brake fluid mark, add Yamaha
approved DOT 4 brake fluid until
the fluid is at the recommended
level. Install and secure the reservoir
cover. Do not allow moisture to con-
taminate the brake system.
Changing Brake Fluid
The brake fluid must be changed on a
regular basis and whenever the brake
fluid has been overheated or contami-
nated. The brake fluid should be changed
every 1600 km (1000 miles) or at the end
of the snowmobiling season, whichever
occurs first. Take the snowmobile to an
authorized Yamaha Snowmobile dealer
for this service. This service is at the dis-
cretion and expense of the snowmobile
owner.
Checking Brake Lever Travel
Before each use, check the brake lever
travel using the following procedure:
1. Compress the brake lever fully.
NOTE: Do not pump the brake
lever as it will produce an inaccu-
rate reading.
2. Measure the distance between the
brake lever and the handlebar. The
distance must be greater than 25.4
mm (1 in.).
SNO-780
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.
CAUTION
Brake fluid is highly corrosive. Do
not spill brake fluid on any surface
of the snowmobile.
WARNING
Do not overfill the brake fluid reser-
voir. Overfilling the reservoir may
cause the brake system to hydrauli-
cally lock. Use only Yamaha
approved DOT 4 brake fluid. Never
substitute or mix different types or
grades of brake fluid. Brake loss
can result. Brake loss can result in
severe injury or even death.
WARNING
Do not operate the snowmobile if
the compressed distance between
the brake lever and the handlebar is
less than 25.4 mm (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.
