Abstract: Squeal is an example of noise caused by vibrations induced by friction forces. Several works have been developed over the last decades. Certain of these works have focused on simplified brake systems and identified 'lock-in' instability as being the cause of squeal. A short bibliography of previous works and the most recent results are presented. Brake design is not capable of avoiding modal coupling due to 'lock-in' sensitivity to system dynamics, high modal density and uncertainties regarding the natural frequencies. This paper suggests an innovative approach for avoiding the growth of vibrations, by making lumped structural modifications to the rotor.
