System and method for detecting operation of a braking system (150) of a vehicle (100). A system for detecting operation (105) of a braking system (150) of a vehicle (100) comprises a microphone (120, 121, 122, 123), and an electronic controller (110), configured to receive an audio signal from the microphone (120, 121, 122, 123), wherein the audio signal is comprised of a sound caused by contact between at least one tire of the vehicle (100) and a driving surface, generate a noise characteristic from the audio signal, compare the generated noise characteristic to a known noise characteristic, and generate a notification based upon the comparison of the generated noise characteristic to the known noise characteristic.
