„ NOTE: The brake band should lock tightly when
the brake lever is compressed and should disen-
gage when the lever is released. If adjustment is
necessary, use the following steps.
1. Loosen the rearward jam nut on the brake cable.
2. Tighten the forward jam nut to set up the brake.
3. Check the brake lever travel distance periodically
while tightening the forward jam nut. When the
distance is within the specified range of 6-13 mm
(1/4-1/2 in.), tighten the rearward jam nut to
secure the adjustment.

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
2.54 cm (1 in.).
734-505A
3. If the distance is less than specified, check the
brake fluid level (see Checking and Adding Brake
Fluid in this sub-section), inspect for leakage, and
check the brake pads (see Checking and Replacing
Brake Pads in this sub-section).
CHECKING AND ADDING BRAKE FLUID
1. With the master cylinder in a level position, check
fluid level in the reservoir. The brake fluid level
must be just below the high mark.
0734-397
2. If the brake fluid level is below the low mark,
remove the reservoir cover and add approved
brake fluid until the fluid level is just below the
high mark. 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 (see Removing/Installing Caliper in this sub-sec-
tion).
! WARNING
Use only Arctic Cat approved Hi-Temp Brake Fluid
(p/n 0638-315). 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.
! WARNING
Do not operate the snowmobile if the distance
between the compressed brake lever and 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
Do not overfill the master cylinder reservoir. Over-
filling 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 Arctic Cat approved brake fluid. Any sub-
stitute may result in a loss of brakes.
