REMOVING/DISASSEMBLING
1. Secure the vehicle on a support stand to elevate the
wheel; then remove the wheel.
2. Drain the brake fluid from the caliper, hose, and mas-
ter cylinder through the bleed screw by pumping the
brake pedal.

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 sig-
nificantly 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.

! WARNING
Arctic Cat recommends only authorized Arctic Cat ROV
dealers perform hydraulic brake service. Failure to
properly repair brake systems can result in loss of con-
trol causing severe injury or death.
! WARNING
Make sure the vehicle is solidly supported on the sup-
port 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.
CAUTION
Brake fluid is highly corrosive. Do not spill brake fluid
on any surface of the vehicle and do not reuse brake
fluid.
