you need to remove the five torx 50 bolts holding the wheel bearing to the hub carrier,look for the holes through the flange,the whole disc/hub then pulls out of the carrier then remove the five 13mm bolts holding the disc to the hub,watch the bearing removal from the carrier,these can be tight,and there is a puller for these but if you are renewing the disc then a large hammer can knock them out if they are tight.Clean up the carrier and bearing and grease on re assembly and they will be a lot easier to remove in the future.
