Checking/Changing Brake Pads; Drive Belt - Arctic Cat 2014 SNO PRO 500 Operator's Manual

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 reser-
voir to a level just below the high 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.
1. Measure the width of both brake pads. The brake
pad width must be greater than 3.2 mm (0.125 in.).
If the brake pad width is less than specified,
replacement of both pads is necessary. Follow
steps 2-6 to replace brake pads.
2. Remove the pin securing the brake pads to the cal-
iper assembly.
3. Remove the brake fluid reservoir cover; then
remove most of the brake fluid from the reservoir.
Replace the cover.
NOTE: The above procedure will allow room for the
fluid from the caliper 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 carefully push
the piston into the caliper.

6. Position the new brake pad into the caliper.
7. Repeat steps 4-6 for the other pad; then secure the
pads with the pin.
8. Remove the reservoir cover and remove the
remaining fluid; then fill the reservoir with fresh
fluid.
9. Pump the brake lever to ensure correct positioning
of the brake pads; then release.
10. Fill the reservoir to the proper level with fresh
brake fluid.
NOTE: When new brake pads are installed, a
"burnishing" process is required. Drive the snow-
mobile slowly and compress the brake lever sev-
eral 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 clutch. If the belt is worn, cracked, or
stretched, maximum power will not be transmitted and
the belt could also fail and therefore must be replaced.
Periodic checks (at least once a week under normal
usage) of two drive belt specifications are essential.
1. Measure the outside circumference of the drive
belt. The belt should be within specifications in
circumference.
2. Measure the outside width of the drive belt. The
belt should be within specifications in width.
3. Check the belt for cracking, fraying, etc.
If any of the specifications or conditions are unsatis-
factory, replace the drive belt.
