A caliper hardware clip including a frame having a top edge, a bottom edge, and a front surface, a first recess formed in the front surface to receive an end of a first brake pad, a second recess formed in the front surface to receive an end of a second brake pad, a separator integrally formed with the frame, the separator including a bridge portion extending forward from a central portion of the top edge of the frame, a first spring arm extending down and left from a left side of the bridge portion along the front surface of the frame, and a second spring arm extending down and right from a right side of the bridge portion along the front surface of the frame.

Provided is a backing plate for a hydraulic brake of a two-wheeled vehicle that is made of plastic material and has a first face and a second face opposite the first face and defining a thickness therewith. The first face is configured to fixedly carry a layer of friction material. An undercut recess, formed within the thickness of the backing plate, opens on the second face and is configured to receive and retain a corresponding portion of a floating piston for brake actuation.

A fixed caliper brake includes a caliper housing that includes two opposing blocks. Each of the opposing blocks includes an axial recess, an axial surface for supporting a brake pad, and elements for mounting and axially and slidably guiding the brake pad. The elements include a pad spring that is attached to each related lug of the brake pad, and a steel lamellar element having a spring and being received in the related recess.

A motor vehicle disc brake lining having friction material fixed on the front side of a back plate, and a resetting spring fixed releasably or non-releasably on the rear side of the back plate with a base and an elastic resetting spring bow. The resetting spring bow sits elastically on an assigned abutment of a holder such that the motor vehicle disc brake lining can be reset to be axially distanced from a brake disc in the released brake state. The friction lining resetting spring has a spring characteristic curve which is additively composed of a plurality of portions including a plurality of quasi-linear straight portions and, interposed in-between, at least one curved transition portion, each having mutually differently defined gradient angles, and among the portions there is at least one portion which is at least partially plastically deformable and serves to automatically allow demand-oriented spring-back based on wear compensation.

This disc brake includes a mounting member, a pair of brake pads, a caliper, and a cover member. The caliper includes a cylinder part having a cylinder hole in which a piston for moving one of the pair of brake pads is disposed, a bridge part extending across an outer circumferential surface of a disc from the cylinder part in a direction of a rotating axis of the disc, a plurality of claw parts extended toward inside from the bridge part in a radial direction of the rotating axis of the disc and disposed on an opposite side from the cylinder part with the disc interposed between the plurality of claw parts and the cylinder part, the recessed part provided between the plurality of claw parts and opening in a position opposing the cylinder, and a locked part formed on an inner circumferential surface of the recessed part.

A return spring (21) made of a metal plate, for biasing a friction pad (6) in a return direction of separating away from a disc (1) is arranged between the friction pad (6) and a mounting member (2). The return spring (21) includes a fixed portion (22), which is on a base end side fixed to an ear portion (7B) of a back plate (7) of the friction pad (6). Then, an abutment portion (25), which is on a distal end side of the return spring (21), is elastically brought into abutment on an abutment plate portion (13D) of a pad spring (13), which is on the mounting member (2) side at a position on an outer side in a disc radial direction relative to the fixed portion (22).

A disc brake for a commercial vehicle is provided. The disc brake includes a brake caliper which engages over a brake disc and is in the form of a sliding caliper, two brake pads which are arranged in the caliper, are movable in opposite directions and each have a pad carrier plate and a friction lining fastened thereon and of which an application-side brake pad is pressable against the brake disc by an application device via at least one brake plunger, and with at least one restoring device with which the brake caliper is returnable after a braking-induced displacement and release of the brake. The restoring device is provided with a friction element which is mounted in the brake pad so as to be displaceable to a limited extent under pressure loading in the axial direction of the brake disc and on which an elastic pressure element held in the brake caliper and/or brake plunger acts.
