A disc has a braking band, a bell and elastic elements. The braking band has a plurality of radial teeth projecting from a radially internal edge portion, delimiting a plurality of band seats. Each radial tooth has a radially internal edge surface, a first and a second axial tooth side, and at least one circumferential side. A plurality of axial teeth project delimiting a plurality of bell seats. The plurality of radial teeth is housed in the plurality of bell seats. The internal bell surface is aligned with the radially internal edge surface of each radial tooth. Each elastic element is removably connected to the axial teeth and embraces a portion of first and second axial tooth sides and of circumferential side of the radial teeth of the braking band, elastically preloading the radial teeth with respect to the bell.

A pad liner for a brake apparatus may include: a pad liner body disposed between a plurality of pin members; pad liner support parts extending from two opposing ends of the pad liner body, respectively, and configured to support the plurality of pin members, respectively; a pad liner return part connected to the pad liner body so as to press a first brake pad, and brought into contact with the first brake pad so as to provide an elastic restoring force when a brake pedal is released, such that the first brake pad is returned to original state; and a pad liner extension part connected to the pad liner body, and brought into contact with a second brake pad so as to press the second brake pad.

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 disc brake assembly includes a brake clip having a U-shaped section, at least one retention tang, and an abutment leg. The U-shaped section has a base leg and opposing upper and lower legs extending from the base leg. The upper leg has an inner face facing the lower leg. The at least one tang extends away from the U-shaped section and inner face. The abutment leg extends from the lower leg and has a midpoint between a top edge and a bottom edge. The midpoint is not planar with the top and bottom edges.

A brake assembly having a retraction spring and a method of assembly. The retraction spring may extend between first and second brake pad assemblies. The retraction spring may include a coil and may have an end or tip that may be received in a hole in a backplate of a brake pad assembly.

An electric brake actuator configured to push a friction member onto a rotary body by advancing a piston by rotating an input shaft by an electric motor, including: a torque imparting device configured to impart, to an input shaft, a torque in a direction to retract a piston based on an elastic torque of a torsion spring and including a mechanism configured to allow a first retained portion provided at one end portion of the torsion spring to be retained by another one of a plurality of first retaining portions of a stator when the elastic torque exceeds a set upper-limit torque to decrease the elastic torque; and a mechanism configured to permit a second retained portion of a rotor to be retained by a second retaining portion provided at the other end portion of the spring to prohibit the elastic torque from becoming smaller than a set lower-limit torque.

A brake assembly having a retraction spring. The retraction spring may be mounted to a first brake pad module and a second brake pad module. The retraction spring may have an anti-rotation feature that inhibits rotation of the retraction spring. The anti-rotation feature may engage the first brake pad module.

A disc brake of a floating type includes: an inner pad and an outer pad respectively located on opposite sides of a rotor rotatable with a wheel; a pressing device configured to press the inner pad and the outer pad against the rotor; and a housing mounted on a non-rotating member and holding the pressing device. The pressing device includes: a first pressing member movable toward the rotor; a second pressing member movable away from the rotor; and a frame having a substantially frame shape and including (i) a first side portion opposed to the second pressing member and (ii) a second side portion engaged with the outer pad and movable together with the outer pad in a direction parallel with a rotation axis of the rotor. The disc brake includes a return spring provided between the frame and one of the housing and the inner pad.

At least one of a pair of pad springs includes a guide plate portion for guiding an ear portion of a corresponding friction pad in a disc axial direction. The guide plate portion includes a first plate portion, a second plate portion, and a bottom plate apportion. A radially biasing portion is configured to elastically bias the ear portion of the friction pad toward the first plate portion; and a rotational direction biasing portion is configured to bias the friction pad in a rotational direction of a disc. The second plate portion is provided with an open portion at a position shifted inward from a middle position in the disc axial direction. The rotational direction biasing portion includes a main biasing portion configured to bias the friction pad inward in the disc rotational direction, and a sub biasing portion arranged across the open portion away from the main biasing portion.

A disc brake assembly includes a brake clip having a U-shaped section and at least one extension portion. The U-shaped section has a base leg and opposing upper and lower legs extending from the base leg. The at least one extension portion has an application portion, a transition portion with first and second legs, and a bend connecting the first and second legs. The transition portion extends in a first direction from a side of the U-shaped section. The first and second legs extend in a direction other than the first direction. The bend redirects the application portion from a second direction to a third direction. The second direction is angled from the first direction.
