The brake disc is mounted to a wheel bearing/hub assembly but the hub does not need to be removed to replace the disc, only the brake caliper and its mounting bracket. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect....
