The reliable and effective performance of a braking system is fundamental to the operation of most vehicles. Any failure in the braking system that impacts the ability to retard a vehicles motion have an immediate and frequently catastrophic effect on a vehicles safety. There are very few diagnostic systems that monitor the health of multiple individual components in a braking system and even fewer that can automatically detect early stage failures and component wear with the reliability required for such an important vehicle subsystem. The systems that can accomplish these tasks are restricted in application due to size, weight and there own unique maintenance loads. Current diagnostic techniques call for careful maintenance of braking system components. These techniques tend to be backward thinking in that they are based on previous experience which is not always a good indicator for future systems. In …
