Abstract
A is a vibration damper suppresses squeaks of a disk brake by positively damping vibrations of the brake. It is a high-performance, highly reliable vibration damper with no accurate machining required. This vibration damper has pressing pistons received in brake pistons so that brake fluid pressure acts thereon. It further includes a vibration detector for detecting brake vibrations through one of two pads, and a vibration imparter for vibrating the other pad based on detection signals of the vibration detector so as to cancel out the vibrations detected by the vibration detector. They are pressed against the back of the respective pads by the respective pressing pistons. By pressing them at a suitable pressure against the pads, it is possible to detect vibrations and vibrate the pads with high reliability. When replacing the pads, they never protrude from the pad pressing surfaces, so that they are less likely to be damaged or destroyed.
