The squealing of disk brakes is an effect of self-excited oscillations that is often explained by the presence of a coefficient of friction that decreases with increasing relative velocity, but also occurs in cases with an almost velocity-independent coefficient. We present a model for a disk brake that shows self-excited oscillations even for a constant coefficient of friction. The model consists of a rotating annular plate and two solid brake blocks. The system behaviour is described by a set of differential algebraic equations. We study the effect of several parameters on the stability of the stationary solution and calculate self-excited oscillations for unstable cases.
