Brake System - Yamaha SR1NLK Operator's Manual

Even after replacing a fuse, it may con-
tinue to blow if the cause of the overload
is not determined. If the fuse continues to
blow, take the snowmobile to an autho-
rized Yamaha Snowmobile dealer for ser-
vice. If not under warranty, this service is
at the discretion and expense of the
snowmobile owner.

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 snowmobile is oper-
ated and the brake system is not func-
tioning properly,
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.

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 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.
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 inaccurate
reading.
2. Measure the distance between the
brake lever and the handlebar. The
distance must be greater than 25.4
mm (1 in.).
