Abstract
Methods and systems for measuring a brake stroke of an air brake assembly utilize a sensor, such as an accelerometer, mountable on a movable component, such as a brake cam shaft, of the air brake assembly that is external of the brake chamber of the air brake assembly for detecting an acceleration of the movable component during a braking event. The sensor generates an output signal that depends on a magnitude of the detected acceleration, which is sent to a microcontroller coupled to the sensor. The microcontroller translates the sensor output signal to a value corresponding to a displacement of the movable component of the brake assembly during the braking event and calculates a brake stroke distance based on said value.
