Being exposed to brake squeal can be very annoying and avoiding this problem has a high priority. Often considerable effort is needed in order to address squeal noise issues for the purpose of development, testing and implementation of vehicle brake systems. A distributed-parameter model of a disc brake is developed, which is used for simulation of friction-induced vibrations in the form of high-frequency squeal. The effect of different squeal generation mechanisms is investigated. The comparison of measured and calculated frequencies shows a good agreement and this study indicates that lining-deformation-induced modal coupling can act as a squeal generator in disc brakes. The detailed study of the effects of decoupling and coupling of modes allows for a better understanding of the mechanisms leading to instability, and it allows for investigations of changes leading to favorable system configurations.
