Abstract: A ferromagnetic brake rotor having an integral tone ring is provided. A sensor is positioned adjacent to the rotor for sensing magnetic property variations in the ferromagnetic brake rotor. Magnetic property variations in a ferromagnetic brake rotor disc are sensed. Rotational properties for a wheel attached to the ferromagnetic brake rotor disc are determined based on the magnetic property variations. A brake system is then modulated based on to the rotational properties the wheel.
