1. A drum brake assembly comprising:
a brake hub-drum, which encloses braking components, having an interior circumferential rim, a plurality of indicia located on said rim, said indicia having a greater distance from an axis of rotation than said interior circumferential rim;
a backing plate, said brake hub-drum rotatable about said axis of rotation with respect to said backing plate; and
a magnetic sensor fixed with respect to said backing plate, said sensor located adjacent said indicia to detect said indicia when said brake hub-drum rotates with respect to said sensor.
