NOTE: Field test the track under actual conditions
and after the field test, check track alignment and
track tension; adjust as necessary.
Brake System
CHECKING BRAKE LEVER TRAVEL
1. Compress the brake lever fully.

NOTE: Do not pump the brake lever as it will pro-
duce an inaccurate reading.
2. Measure the distance between the brake lever and the
handlebar. The distance must be greater than 1 in.
0745-816
3. If the distance is less than specified, check the brake
fluid level, inspect for leakage, and check the brake
pads.
CHECKING AND ADDING BRAKE FLUID
1. With brake fluid reservoir in a level position and the
cover removed, check the fluid level. The brake fluid
level must be at the high mark in the reservoir.
0745-817
2. If the brake fluid level is low, add Arctic Cat
approved brake fluid until the fluid is at the recom-
mended level. Install and secure the reservoir cover.
DO NOT allow moisture to contaminate the brake
system.
CHANGING BRAKE FLUID
The brake fluid must be changed on a regular basis
and/or whenever the brake fluid has been overheated or
contaminated. The brake fluid should be changed every
1000 miles or at the end of the snowmobiling season,
whichever occurs first.
Arctic Cat recommends the removal and disassembly of
the brake caliper assembly when changing the brake
fluid.
1. Slide a piece of flexible tubing over the ball of the
bleeder valve and direct the other end into a con-
tainer.

2. Slowly compress the brake lever and hold. Open the
bleeder valve to release the fluid; then compress the
brake lever repeatedly until all brake fluid is
expelled. Close the bleeder valve.
3. Add new approved brake fluid to the reservoir; then
compress the brake lever and hold. Open the bleeder
valve. Repeat the compression until brake fluid
flows free of air bubbles and appears clean.
! WARNING
Do not operate the snowmobile if the distance between
the compressed brake lever and handlebar is less than
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
Do not overfill the brake fluid reservoir. Overfilling the
reservoir may cause the brake system to hydraulically
lock. Use only approved brake fluid. Never substitute or
mix different types or grades of brake fluid. Brake loss
may occur. Brake loss can result in severe injury or
even death.
CAUTION
Brake fluid is highly corrosive. Do not spill brake fluid
on any surface of the snowmobile.
! WARNING
Use only DOT 4 or DOT 5 brake fluid. Any substitute
may result in a loss of brakes.
