Abstract: An electric parking brake device includes an inner engaging part formed on an inner shim, wherein the engaging part engages with a projection projecting from the back face of an inner brake pad so that mutual rotation about the central axis of a piston is controlled. An outer hook is formed on an outer shim, wherein the outer hook slidably locks to the outer circumferential edge of an outer brake pad. The outer hook is configured so that at least one of same is provided on each of an outer circumferential end on the outside of and an outer circumferential end on the inside of the outer brake pad in the radial direction and so that the set spring constant allows the outer shim to move to the outside in the radial direction with respect to the outer brake pad while the parking brake is applied.

Abstract: A laminated shim for a disc brake has a pad side shim and a pressing member side shim. The pad side shim is provided at a backside of a backing plate of pad. The pressing member side shim is disposed between the pad side shim and a pressing member used for pressing the pad against a rotor. The pad side shim has hooks that extend over and are hooked onto a peripheral edge of the backing plate. The pressing member side shim has hooks that extend over a surface of a respective pad side hook. The pressing member hooks are slidably contacted to the top of the hooks of the pad side shim so as to be easy to slide in a surface direction with respect to the pad side shim and the backing plate of the pad.

Abstract: A disc brake caliper assembly for use with a disc rotor includes first and second opposed pads positionable on opposite sides of the disc rotor and movable towards and away from one another to apply a braking force to the disc rotor during braking operation, and a stationary member which receives a braking torque from the pads during the braking operation. A single pad-supporting pin has opposite ends that are supported by the stationary member, and the single pad-supporting pin is adapted to support the pads in the radial direction. The pad-supporting pin is located at a position offset from the center of each of the first and second pads. A one-piece spring member is supported on the stationary member.

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.
