I am not an expert, but you´ll have to check the brake pads, maybe there are worn off and the sensor attached to the pads is broken, that is the way it works, choose the wheel where the sensor is attached and see if the tip is broken by the pads or check the plug where the sensor is connected, it might be dirty or the cable could be damaged.
