A caliper for disc brake comprising a caliper body housing at least one pair of pads disposed on opposite sides along an axial direction and comprising at least one thrust piston which interfaces with the pad so as to press it against the associable brake disc, and at least one return spring that exerts a return thrust on the support plate of the pad. The return spring comprises a fixing portion to the caliper body that extends from axially opposite sides in separate thrust branches, each thrust branch interfacing with a support plate of a related pad. Each thrust branch comprises a first rectilinear portion that extends towards the corresponding pad, a curved portion, integral with the first rectilinear portion and folded in approach to the fixing portion, a second rectilinear portion that extends from the curved portion in approach to the fixing portion. The second rectilinear portion terminates with a free cantilevered end and interfaces with an edge of the support plate.

A motor-vehicle fixed-caliper partially lined disk brake with pin mounting for backing plates of disk brake linings, comprising a one-piece clearance spring with two spring legs which are elastically clamped in between the backing plates on a bearing portion which is free of friction material.

A pad clip in which a circumferential dimension from a first contact portion in contact with a side surface of a coupling portion, which is disposed on the other side in the circumferential direction, on the one side in the circumferential direction in a fixing portion disposed on the other side to a side surface of a sandwiched plate portion on the one side is available to be set independently of a circumferential dimension from a first contact portion to a second contact portion in contact with the side surface of the coupling portion, which is disposed on the one side, on the other side in the fixing portion disposed on the one side. The side surface of the sandwiched plate portion is in surface contact with a torque-receiving surface regardless of bending deformation generated in a main body portion based on elastic deformation of a pressing portion.

Disclosed are a pad spring and a caliper brake having the same. The pad spring, which is installed on a coupling projection protruding from a carrier to slidably support a pair of pad plates, includes a first return part formed to extend downwardly from an upper side of the pad spring to elastically support and return the pad plate to its original position, and a second return part spaced apart from the first return part by a predetermined distance and provided at a position where the first return part is elastically deformed depending on an operation of the pad plate, wherein when the first return part is elastically deformed, the second return part comes into contact with the first return part to be elastically deformed together with the first return part and apply an elastic restoring force to the pad plate.

A brake pad may have at least one plate and at least one friction material supported by the plate. The friction material surface may have a barycenter. The plate may have a first slot and a second slot. The first slot may have a first slot edge adapted to accommodate a first pin mounted on the caliper body. The second slot may have a second slot edge adapted to accommodate a second pin mounted on the caliper body. In a forward braking condition, the brake pad rests on the first pin with a first slot first portion, and the brake pad rests on the second pin with a second slot first portion. The first slot is arranged in a radially outer position with respect to the barycenter and the second slot is arranged in a radially inner position with respect to the barycenter. The first slot and the second slot may be radially external with respect to a barycenter circumference centered on a rotation axis and passing through a barycenter.

The disclosure relates to the technical field of vehicle accessories, and particularly provides a brake for a vehicle and a vehicle. The disclosure aims at solving the problem that existing brakes for a vehicle usually cannot overcome low-frequency stubborn noise generated by a caliper structure in the brake in a braking process. For this purpose, the brake for a vehicle according to the disclosure comprises a first caliper body and a second caliper body, wherein the first caliper body and the second caliper body are provided with a first friction disc and a second friction disc respectively, a brake disc is arranged between the first friction disc and the second friction disc, and the first friction disc and the second friction disc are each further provided with at least one mass block, so as to quickly reduce low-frequency operating noise of the brake, thereby fundamentally eliminating braking noise, and then solving the problem that the existing brakes for a vehicle usually cannot overcome low-frequency stubborn noise generated by a caliper structure in the brake in a braking process.

A brake pad assembly for a bicycle includes a first brake pad, a second brake pad, and a spreader spring. The first brake pad has a first backing plate with a first rotor facing surface, and a first friction pad secured to the rotor facing surface. The second brake pad has a second backing plate with a second rotor facing surface, and a second friction pad secured to the second rotor facing surface and facing the first friction pad. The spreader spring has a first leaf that is fixed to the first brake pad and a second leaf that is fixed to the second brake pad. At least a portion of the first leaf is positioned between the first rotor facing surface and the first friction pad, and at least a portion of the second leaf is positioned between the second rotor facing surface and the second friction pad.

Provided is a caliper brake pad spring applying load to a brake pad in a set position. A spring mounting unit is mounted on a window of a caliper body. Spring pressing units extend from both sides of the spring mounting unit in one direction to apply load to a brake pad by pressing the brake pad.

A spring for a caliper body where the spring may be shaped to be arranged straddling a brake disc for applying an elastic action on at least one brake pad to bias it away from said brake disc. The spring may have a first thrust portion and a second thrust portion adapted to apply an elastic action on at least one brake pad, biasing the brake pad at least away from the brake disc. The spring may also have a first coupling portion adapted to couple the spring with a first side bridge. The spring may also have a second coupling portion adapted to couple the spring with the second side bridge on a tangentially opposite part with respect to the first coupling portion. The spring may also have a backing portion. The spring may also have at least one concave spring portion.

The present invention is a vehicle disc brake for which incorrect installation of a friction pad can be prevented with a simple structure. The disc brake is provided with incorrect installation-preventing parts with which, if a friction pad (4) is installed with an incorrect installation orientation when a pair of tabs (10, 11) provided on the disc entry-side and disc exit-side of the back plate (4d) of a friction pad (4) is installed into pad guide grooves (9) formed on a caliper body (3), the tabs bump into the caliper body (3) and prevent the incorrect installation. The incorrect installation-preventing parts are formed from caliper-side recesses (9d, 9e), which are formed in the pad guide grooves (9) towards the center of the caliper body, and tab-side protrusions (10a, 11a), which have shapes that correspond to the caliper-side recesses (9d, 9e).
