The focus of this article is to show and discuss the nonlinear dynamical behaviors of brake system subjected to friction-induced vibration that can be generated due to the co-existence of multi-unstable modes. A finite element model with friction coupling is used to analyze the stability of the brake system and the stationary nonlinear oscillations for squeal noise prediction. The mechanism of squeal instability considers a mode coupling phenomenon that is classically referred to as coalescence.
