I was gonna take my rotors off last weekend to have them turned down. I loosened the caliper and then I realized there was a fairly large nut holding the rotor on. I have no sockets that big either. Does anyone know what size it is? It also seems like it would be highly torqued too. Is there a special way to take it off? Didnt know if using a flex bar could mess something up being it is front wheel drive, any answers guys?
