This study presents the stability analysis of a disk brake which consists of a disk and a pad supported by a plate spring (pad-caliper). The squeal vibration of the disk near the contact area between the disk and the pad has translational motion, and the squeal vibration of the pad-caliper has translational and rotational motion. We made a distributed spring model based on numerical analysis of the pin-disk model to clarify influence of a distribution of the load on a contact area. It could take into consideration restoring force on frictional contact surface occurred by elastic deformation which depended on load. We considered the spring was nonlinear in case pressing load was large. It is the cause that the frequency of squeal is depending on load.
