Brake rotor cracking problems become increasingly important for heavy commercial vehicles. Existing test procedures are typically very time-consuming, predominantly empirical, and their results are subject to controversial discussions. Based on the analysis of established crack test procedures, a field analysis has been started for both road-load data and crack failure patterns. Possible programme modules are investigated by FEA (finite element analysis) and experiments using new thermal methods of investigation. A new method of crack testing was successfully demonstrated allowing for short-term crack prediction on a dynamometer test stand. The development of superior crack test procedures based on field data and scientific tools appears to be indispensable. A first draft for a future crack test procedure is proposed, inviting the braking community to join on-going development efforts.
