A drum braking system having a spindle and backing plate affixed thereto. The system includes a drum rotating on the spindle. The drum has an inside surface with integral notches that are machined or cast into the drum. When the brakes are applied, brake shoes are actuated to contact the inside surface to create drag between the drum and the spindle. A sensor is fixed with respect to the spindle or backing plate that detects the notches when the drum rotates about the spindle. A portion of the inside surface with the integral notches is shared with the brake shoes so that applying the brakes prevents buildup that could contact the sensor. The sensor is positioned radially to reduce the effect of drum endplay on detecting of the notches.
