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 following 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 snowmo-
bile to an authorized Arctic Cat
Snowmobile dealer for this service.
This service is at the discretion and
expense of the snowmobile owner.
1. Remove the reservoir cover and fill
the
reservoir
with
Arctic
Cat
approved DOT 4 brake fluid.
2. Slide a piece of flexible tubing over
the ball of the bleeder valve and
direct the other end into a container.

3. Slowly compress the brake lever and
hold. Open the bleeder valve to
release the fluid and air. When the
fluid stops, close the bleeder valve;
then release the brake lever.
4. Repeat step 3 until the brake fluid
flows free of air bubbles.
NOTE: It may be necessary to refill
the reservoir during the bleeding
process.
5. When the brake fluid is free of all air
and the brake lever feels firm when
compressed, fill the reservoir; then
install and secure the cover. Remove
the tube from the bleeder valve.
Checking/Changing Brake
Pads
The condition of the brake pads must be
checked daily and changed if worn or
damaged. To check and change the brake
pads, use the following procedure:
NOTE: The brake pads may be
changed by the snowmobile owner if
qualified to do so. If the owner does
not feel qualified, take the snowmo-
bile to an authorized Arctic Cat
Snowmobile dealer for this service.
This service is at the discretion and
expense of the snowmobile owner.
NOTE: When installing new brake
pads, always install them as a set.
Never install just one pad or use
brake pads which have been used in
another snowmobile.
1. Measure the thickness of both brake
pads. Brake pad thickness must be
greater than 5.0 mm (0.20 in.). If brake
pad thickness is less than specified,
replacement of both pads is necessary.

2. Remove the pin/hairpin clip securing
the brake pads to the caliper assembly.
3. Remove the brake fluid reservoir cover;
then remove most of the brake fluid
from the reservoir. Install the cover.
! WARNING
Do not operate the snowmobile if the
compressed distance between the
brake lever and the 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
Use only Arctic Cat approved DOT 4
brake fluid. Any substitute may result
in a loss of brakes.
