A rotor such as a brake disk for a vehicle has a spring holder that circumferentially extends around an axis of the disk. A coil spring extends around the axis along the spring holder. The spring is loaded onto the spring holder by its own resilience. The spring has a load rate that generates a tension that allows the spring to move circumferentially relative to the spring holder.
