Abstract
A vibration damper system which can restore the performance of piezoelectric elements that have deteriorated in performance due to temperature buildup resulting from repeated braking operations by applying high voltage at a predetermined time. In the vibration damper system for a vehicle brake including a vibration detector for detecting vibration by pads and a disk rotor and adapted to transmit a vibration damping signal to a vibrator through a control circuit to suppress vibration, when a performance deterioration restoration timing signal is inputted from the ignition switch, the control circuit produces a performance restoration command signal to changeover switches, thus applying high voltage from a high voltage source for a predetermined time (about one second) to restore deteriorated piezoelectric properties.
