The invention relates to a pad clip (5), comprising at least one retainer (6) for supporting a brake pad (2), and at least one retraction spring (10) for retracting the brake pad (2) in an axial direction upon a brake release, the retraction spring (10) having a spring body (17) with a first portion (11), a second portion (12), and an intermediate portion (13) connecting the first and second portions (11, 12), the first portion (11) comprising a contact portion (14) for contacting the brake pad (2), the second portion (12) being configured to be attached to a calliper support bracket (3), wherein the material of the first portion (11) axially extending between the contact portion (14) and the intermediate portion (13) is configured to be stretched in the axial direction upon a brake action and to return to its unstretched state upon a brake release. The invention also relates to a calliper support bracket (3) and a brake assembly (1).

A spring for friction pads which can be associated with a caliper of a disc brake to bias the friction pads elastically away from a brake disc may have a central stretch and two opposite transverse stretches, extending from the central stretch in two opposite transverse directions and each forming a supporting stretch, a resting stretch and a wing stretch extending between the supporting stretch and the resting stretch. The supporting stretches lie on the same supporting plane and the wing stretch may have an ascending wing stretch and a descending wing stretch. The spring may also have one or more fixing stretches connected to the central stretch and forming at least two opposite fixing stretches for elastic snap fixing to corresponding fixing seats of the caliper.

A spring device for a disc brake, a pad and spring assembly for a disc brake, a brake caliper, and a disc brake is described. The spring device may have a spring body having prevalently longitudinal development, with at least one coupling portion, to couple in a snapping manner the spring device to a portion of an associable brake caliper in a removable manner. The spring pad assembly may have at least one brake pad having at least one ramp surface, inclined with respect to the radial direction and to the tangential direction, which forms an abutment reference for the at least one thrust surface of the spring device. The at least one ramp surface of the support plate puts in traction the spring device.

A radially biasing portion (19) of a pad spring (14) includes a first extending portion (19A) extending from a lower surface plate (18B) of a guide plate portion (18) outwardly in a disc axial direction, a curled portion (19B) folded on a distal end side of the first extending portion, and a second extending portion (19C) extending from the curled portion in a direction approaching a disc (1), the second extending portion with which an ear portion (11A) of a friction pad (10) comes into contact. A contact portion (20) extends from the second extending portion of the radially biasing portion (19) toward a middle of the friction pad in a disc rotational direction of the friction pad. The contact portion comes into surface contact with a contacted surface (11B) as a lateral surface of the friction pad (backing plate 11) in the disc rotational direction.

A hydraulic brake and electronic parking integrated caliper includes a base, a main body movable relative to the base, two brake pads movable relative to the main body, two hydraulic pistons for pushing the brake pads, an electronic drive fixed to the main body, a threaded rod driven by the electronic drive to rotate, and a linearly displacing member displaceable relative to the threaded rod. When moving from a first position to a second position, the linearly displacing member pushes a hydraulic piston and a brake pad toward a direction to press against a brake disc. When moving from the second position to a third position, the linearly displacing member moves the threaded rod, electronic drive and main body toward another direction to make the other hydraulic piston and brake pad press against the brake disc. The caliper has simple structure and generates larger clamping force.
