tap it with a hammer.. try to get a screwdriver between the spindle and the caliper bracket. it has to come out evenly so go around. its a real pain in the butt the first time you take it off so make sure to get some Anti-Seize in between the 2 pieces so that next time it will come out easy. There are some pullers you can buy/rent.. But a screwdriver and hammer work well... Good luck.
