| Research Abstract |
Static stiffness of brake pad influences brake feelings. On the other hand, the stiffness of the pad when vibration is added to the pad is larger than static stiffness. This stiffness in dynamic condition depends on brake pressure and this is one of the causes of squeal generation. In this study, we developed the equipment which can measure both static stiffness and stiffness in dynamic condition. This equipment is useful to develop a brake pad with sufficient braking performance and squeal less
