1. A system for measuring brake data from a drum brake assembly of a vehicle, the drum brake assembly including a brake chamber which actuates a push rod when vehicle brakes are applied, actuation of the push rod causing a rotary motion of an adjuster arm and attached slack adjuster head around a cam shaft, the system comprising:
a brake sensor mounted to the drum brake assembly and configured to measure brake data including a displacement of the drum brake assembly during braking, the brake sensor configured to transmit the brake data over a wireless vehicle area network,
wherein the drum brake assembly is configured to rotate an s-cam when the brakes are applied such that the s-cam engages two cam followers coupled to opposing brake shoes, and
wherein the displacement of the drum brake assembly is representative of a difference in displacement distance between the two cam followers when the drum brake assembly is in a disengaged state and when the brake assembly is in an engaged state.
