Damping plays an important role in controlling brake squeal caused by the coupling between the rotor and the pads. Since most of the damping in the system (during brake squeal conditions) is coming from the pads, it becomes important to understand the relationship between the damping of the pad by itself in its free-free condition and that of the system in terms of braking pressure, temperature, and frequency. This relationship will help in understanding the effects of optimizing the damping of the pad, whether the damping comes from the friction material, backing layer, or add-on damping treatments. The purpose of this paper is to show that the modal strain energy method can be used to arrive at such a relationship.
