This study presents experimental and analytical results of squeal vibration in the disk-pad-caliper system which is modeled based on an actual brake. The frequency of squeal becomes higher as the thrust pressure grows large. To clarify this phenomenon, we examine the dynamic stiffiness between disk and pad. As a result of the experiment, dynamic stiffness grows large when the thrust pressure grows large. Then we analyzed the disk-pad-caliper system as a distributed dynamic stiffness model. This model considers the distribution of the thrust pressure and the dynamic stiffness in the contact region.
