Digital Brake Stroke Sensor

Faulty brakes on heavy trucks continue to be a leading cause of vehicle-based Out-of-Service (OOS) violation citations, and are a contributing factor in many heavy truck crashes. In order to allow the driver and fleet manager to quickly diagnose one functional aspect of the vehicle's braking system, an electronic brake stroke sensor has been developed. This paper discusses the development and operation of the digital brake stroke sensor along with initial in-lab test results.
