Abstract: Brake system telemetry systems and methods utilize wireless communication technology to communicate brake system data to one or more vehicle electronic control modules. A wireless transceiver is provided and is operably disposed with the brake system components. The wireless transceiver is coupled to receive data from various components of the brake system at the respective and to communicate the data to one or more electronic control units within the vehicle.
