Brake System - Yamaha SR10ARLG Owner's Manual

Brake System

Yamaha recommends that the brake sys-
tem (brake lever, fluid reservoir, hose,
caliper, pads, and brake disc) be checked
daily for fluid leakage, wear, or damage
and for proper operation. Also, the brake
fluid level must be checked every time
before starting the engine.
WARNING
DO NOT operate the snowmobile
when the brake lever lock is
engaged or when any component in
the brake system is damaged, worn,
or adjusted improperly. If the snow-
mobile is operated and the brake
system is not functioning properly,
severe personal injury could result.
Checking/Adding Brake Fluid
1. With the brake fluid reservoir in a
level position
removed, check the fluid level. The
brake fluid level must be at the high
brake fluid mark in the reservoir.
High Brake Fluid Mark
Low Brake Fluid Mark
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.
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
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.
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 2.54
cm (1 in.).
