Technician A is correct. The rotor is indeed attached to the hub or axle and rotates at the same rate as the wheel. Technician B's description is incorrect as it refers to a drum brake system, not a rotor brake system. A rotor brake system uses brake calipers that clamp against the rotor to stop the vehicle.
