The dynamics and, in particular, the NVH phenomena in brakes are still in the focus of research. Recent investigations of, for example, Rhee et al show two principal vibrational forms of the linings on the rotor. The first form is characterized by vibrations, where both linings are in phase. This produces in plane vibrations of the rotor and results in high-frequency squeeling events in the brake. The second form is an antiphase vibration of the brake linings with respect to each other. This produce directly out of plane vibrational modes of the disc. This results in lower-frequency caliper and rotor oscillations. One hypothesis is that different wear densities of the linings essentially characterize the two vibrational modes. This paper deals with a low dimensional dynamical system and examines the vibrations, the associated wear characteristics, and analyzes essential influencing parameters on the different vibrational events.
