Considering the types of wear that occur between the pads and the disc, the study begins by presenting Archard’s fundamental wear law. It explains how the hardness and roughness of materials can influence the wear rate. Furthermore, the analysis describes factors influencing the wear coefficient, including chemical affinity between materials, surface quality, thermo-elastic instability (TEI) of the materials, and environmental effects. The paper also presents detection systems for brake pad wear, such as sensors-based monitoring and artificial neural networks (ANNs). These systems monitor brake pad wear in real time, thereby improving the driving safety by alerting the driver to the condition of the brake pads. The principles and systems analyzed form the basis for predictive maintenance, minimizing the risks of brake failure due to excessive wear.14653267enghttp://creativecommons.org/licenses/by-nc-nd/4.0/Archard’s wear lawartificial neural networksbrake pad wearchemical affinitysensor-based monitoringsurface qualitythermo-elastic instabilitywear mechanismsChemical affinityArtificial neural networksSurface qualityWear mechanismsSensor-based monitoringBrake pad wearThermo-elastic instabilityArchard's wear lawAutomotive EngineeringElectrical and Electronic EngineeringYesyesreview articleopen access10.3390/vehicles7020052https://www.scopus.com/pages/publications/105009275640https://www.scopus.com/pages/publications/105009275640#tab=citedBy
