1. Measure the thickness of both brake
pads. The brake pad thickness must
be greater than 5.0 mm (0.20 in.). If
the 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.
NOTE: The above procedure will
allow room for the fluid from the cali-
per when the pistons are pushed
into the caliper for installing new
brake pads. Replacing the cover will
prevent fluid spillage.
4. Using a pair of pliers, pull one brake
pad out of the caliper assembly.
NOTE: Changing one pad at a time
will prevent one piston from pushing
out the other piston from the caliper.
5. Using a flat-blade tool, slowly and care-
fully push the piston into the caliper.
6. Position the new brake pads into the
caliper.
7. Repeat steps 4-6 for the other pad;
then secure the pads with the pin/
hairpin clip.
8. Remove the reservoir cover and
remove the remaining fluid; then fill
the reservoir with fresh fluid and
install the cover.
9. Pump the brake lever to ensure cor-
rect positioning of the brake pads;
then release.
10. Remove the reservoir cover and fill the
reservoir to the proper level with fresh
brake fluid; then install the cover.
NOTE: When new brake pads are
installed, a “burnishing” process is
required. Drive the snowmobile slowly
and compress the brake lever several
times until the pads just start to warm
up; then allow them to cool down. This
procedure stabilizes the pad material
and extends the life of the pads.
Drive Belt
The drive belt transfers power from the
drive clutch to the driven pulley. If the
belt is worn, cracked, or stretched, maxi-
mum power will not be transmitted and
the belt could also fail and therefore must
be replaced. Periodic checks (at least
once a month under normal usage) of two
drive belt specifications are essential.
1. Measure the outside circumference
of the drive belt. The belt should be
within the recommended range in
circumference.
2. Measure the outside width of the
drive belt. The belt should be within
the recommended range in width.
3. Check the belt for cracking, fraying, etc.
If any of the specifications or conditions
are unsatisfactory, replace the drive belt.
NOTE: Drive belts should be pur-
chased from an authorized Arctic
Cat Snowmobile dealer, as Arctic Cat
drive belts are made to exact specifi-
cations and of quality material. Belts
made by other manufacturers may
not be of the same specifications or
quality and, therefore, usage could
result in poor performance and pre-
mature belt failure.
NOTE: Before starting the snowmo-
bile in extremely cold temperatures,
the drive belt should be removed and
warmed up to room temperature.
Once the drive belt is at room temper-
ature, install the drive belt.
Also, new drive belts have a break-in period
of approximately 25 miles. After installing a
new drive belt, drive the snowmobile for 25
miles at 3/4 throttle or less. By revving the
engine up and down (but not exceeding 60
mph), the exposed cord on the side of a new
belt will be worn down. This allows the
drive belt to gain its optimum flexibility and
will extend drive belt life.
