to misalignment of the nut, tighten the nut until prop-
erly aligned and the plate is fully seated.
5. Install the wheel and using a crisscross pattern, tighten
the wheel nuts in 20 ft-lb increments to a final torque

! WARNING
Arctic Cat recommends only authorized Arctic Cat Wild-
cat dealers perform hydraulic brake service. Failure to
properly repair brake systems can result in loss of con-
trol causing severe injury or death.
REMOVING/DISASSEMBLING
1. Secure the vehicle on a support stand to elevate the
wheel; then remove the wheel.
! WARNING
Never let brake fluid contact the eyes. Damage to the
eyes will occur. Always wear appropriate protective
safety goggles and latex gloves when handling brake
fluid.
2. Drain the brake fluid from the caliper, hose, and mas-
ter cylinder through the bleed screw by pumping the
brake pedal.
CAUTION
Brake fluid is highly corrosive. Do not spill brake fluid
on any surface of the vehicle and do not reuse brake
fluid.
 NOTE: Whenever brake components are removed,
disassembled, or repaired where brake fluid is
exposed to air, drain all fluid and replace with new
DOT 4 brake fluid from an unopened container. Brake
fluid readily absorbs moisture from the air signifi-
cantly lowering the boiling point. This increases the
chance of vapor lock reducing braking power and
increasing stopping distance.

3. Remove the brake hose from the caliper and close the
bleed screw; then remove the caliper.
4. Compress the caliper holder against the caliper (oppo-
site the O-ring side) and remove the outer brake pad;
then remove the inner brake pad.
 NOTE: If brake pads are to be returned to service,
do not allow brake fluid to contaminate them.

5. Remove the caliper holder from the caliper and dis-
card the O-ring.
 NOTE: The O-ring is used for shipping purposes
and provides no function in operation.
6. Cover the piston end of the housing with a shop towel;
then keeping fingers clear of piston travel, apply com-
pressed air to the fluid port to blow the piston free of
the housing. Account for two seal rings in the housing.
