Abstract: A disk brake pad controls rotation of a disk rotor by pushing a friction surface against the disk rotor while it is rotating. The disk brake pad is formed with respective chamfered portions at respective end portions of the disk brake pad at the incoming and outgoing disk-rotor-rotation sides thereof. An edge of an end portion of the friction surface of the disk brake pad at the incoming disk-rotor-rotation side, and an edge of an end portion at the outgoing disk-rotor-rotation side are formed in a stepped bending shape such that a length of the friction surface in a circumferential direction of the disk rotor becomes shorter in a center of rotation direction of the disk rotor.

Abstract: A disc brake which can suppress pad vibration includes an outer pad which while contacting the disc rotor is turned such that the side wall of a guide groove in a support arm on the outer peripheral side abuts with the side face of a projecting section on the outer peripheral side of the pad. A pad support is positioned between the guide groove and the projecting section. The pad support includes a supporting portion, an urging portion and a connecting portion. A projection is provided in the region a little to the bottom of the guide groove on the side face of the projecting section on the outer peripheral side.

Abstract: A pad clip for a disc brake includes a base portion for engaging with a concave portion of a mounting member of the disc brake, a spring portion which extends from the base portion for forcing a projection portion of a disc pad of the disc brake which is fit into the concave portion in the radial direction of the wheel and a curved extension portion which connects the spring portion to the base portion.
