you'll need to remove the brske caliper and torque member, the torque member is what holds the pads.

next remove the dust cover in the center of the hub.

next remove the 2 screws that secure the locking ring and remove it.

next use a punch to unscrew the threaded locking ring.

then pull off the rotor, be sure to catch the front wheel bearing, don't let it hit the ground, you'll need a new one if you do.

flip the rotor/hub assembly over, on the back side you'll se 6 bolts, remove them to seporate the hub from the rotor.
