This study presents experimental results and theoretical analysis of squeal in the two-disks system, which is modeled after actual clutches or brakes. The system consists of a disk clamped along the inner edge and freed along the outer edge and a disk freed along both edges. It was observed that damping is more effective on squeal in high order modes. Thus the squeal frequency becomes lower as damping is increased. No squeal is generated when damping of two disks is over a limit in a state plane. To express the influence of damping on squeal theoretically, equations of motion with viscous damping terms are investigated and the characteristic equation is derived from them. Damping ratios of two disks have much effect on the squeal propensity which is a real part of the root of the characteristic equation.
