3. Slowly compress the brake
l e v e r a n d h o l d . O p e n t h e
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 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 fol-
lowing procedure:

NOTE: The brake pads may be
ch a n g e d by t h e s n ow m o b i l e
owner if qualified to do so. If the
owner does not feel qualified,
take the snowmobile to an autho-
riz ed Arctic C at Snowmobile
dealer for this service. This ser-
v i ce is a t t h e d i s c r e t i o n a n d
e x p e n s e o f t h e s n o w m o b i l e
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 snow-
mobile.

1. Measure the thickness of both
brake pads. The brake pad
thickness must be greater than
3.2 mm (0.125 in.) on the stan-
dard caliper or greater than 5.0
mm (0.20 in.) on the ACT drive
caliper. If the brake pad thick-
ness 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 reser-
voir cover; then remove most of
the brake fluid from the reser-
voir. 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 install-
ing new brake pads. Replacing
the cover will prevent fluid spill-
age.
