Abstract
A disk brake which is designed so that the sound pressure level of the alarm is stable. The disk brake includes a wear sensor composed of a mounting portion which is attached to an outer pad, and a pair of vibrating pieces extending circumferentially of a disk from the left and right ends of the mounting portion along a surface of the outer pad. Each vibrating piece includes an extended portion extending from the mounting portion, and a contact portion formed at the distal end of the extended portion in such a manner that the contact portion is bent toward the disk so as to extend around an edge of the outer pad. The contact portion has a distal end which is offset in the radially outward direction of the disk. The distal end of the contact portion is offset in the radially outward direction of the disk so that the end portion that comes in sliding contact with the disk lies within a braking surface of the disk which is in contact with the outer pad. The portion of the disk that is inward of the braking surface readily gathers rust. Therefore, the distal end of the contact portion is offset so as not come in contact with the portion where rust readily accumulates.
