The aim of this work is producing the disc brake that the squeal is not generated fundamentally. A design manual of the disc brake considering support methods and support positions of caliper was proposed. On the other hand, a dynamic absorber was attached to a basic self-excited vibration system caused by Coulomb's friction, and optimal parameters of dynamic absorber which controls the squeal were studied analytically. Moreover, optimal dynamic absorber from analysis was attached to an experimental apparatus, and the effectiveness of the dynamic absorber was confirmed
