Hydraulic Brake Caliper

! WARNING
Arctic Cat recommends that only authorized Arctic Cat
ATV 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 ATV on a support stand to elevate the
wheel; then remove the wheel.
! WARNING
Make sure the ATV is solidly supported on the support
stand to avoid injury.
! 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 lever/pedal.
CAUTION
Brake fluid is highly corrosive. Do not spill brake fluid
on any surface of the ATV 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
(opposite 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 compressed air to the fluid port to blow the
piston free of the housing. Account for two seal rings
in the housing.
