This thesis project was born from the collaboration between Politecnico di Torino and the Proactive Quality department of Maserati where I had the opportunity to spend six splendid months, working in close contact with the best engineers and workers. The aim of this thesis was initially focused on the implementation of a telemetry monitoring software in the diagnosis of problems affecting vehicle’s chassis. However, an emerging issue affecting the rear brake mechanism has brought the topic of this dissertation into a specific root cause analysis of the problem by applying a diagnostic approach learnt during this internship. The phenomenon is related to the uneven wear of brake pads, fitted on the rear brake caliper of some company vehicles.
