This article presents the results of brake disc tests aimed at identifying the causes of its failure. The first part of the article presents an analysis of the damageability of selected vehicle components, which showed that among the reported failures, the most failure was the braking system.
The assessment of the brake disc worn "properly" as a result of operation and the deformed brake disc after a very short period of operation, which was the subject of further analysis. The next part of the article presents issues related to the modeling of thermal loads, and then, trying to assess and search for the cause of abnormal wear of the brake system element, the use of the Finite Element Method for the analysis and assessment of brake disc wear was proposed. In the final part of the article, conclusions and directions for further work were formulated.
