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 follow-
ing 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 (if
necessary) fill the reservoir to the
high brake fluid mark with Arctic
Cat approved DOT 4 brake fluid.
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.
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
until maximum pressure is attained;
then hold the lever in the com-
pressed position to maintain pres-
sure. 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. Never allow the brake fluid
to go below the low brake fluid mark
in the reservoir.
5. When the brake fluid is free of all air
and the brake lever feels firm when
compressed, fill the reservoir to the
high brake fluid mark; 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. Remove the brake fluid reservoir cover;
then remove most of the brake fluid
from the reservoir. Install the cover.
Brake fluid is highly corrosive. Do not
spill brake fluid on any surface of the
snowmobile.

NOTE: The above procedure will
allow room for the fluid from the cali-
XM145A
per when the pistons are pushed
into the caliper for installing new
brake pads. Replacing the cover will
prevent fluid spillage.
2. Open the left-side access panel.
3. Remove the torx-head screws secur-
ing the brake shield to the belt guard
mount; then remove the cap screws
securing the brake shield to the
brake caliper.
CAUTION
