A pad-and-spring assembly has a supporting plate supporting friction material. The supporting plate has a disc facing surface, a plate back, and facing thrust structure. The friction material has a radially inner edge, and a radially outer edge, radially opposite to the radially inner edge, and defining the outer radial dimension level of the friction material with its tangential extension on the disc facing surface. The disc facing surface has a free surface located radially inside with respect to the tangential extension of the radially outer edge of the friction and having a through opening edge delimiting a through opening. An elastic device of the assembly has a body having at least one connecting portion, connecting to the body of the brake caliper and a supporting portion, axially crossing the through opening to apply elastic biasing action directly in axial direction to the through opening edge.

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.

A disc brake pad which is supported by a pair of pins to a pad support member so that the disc brake pad is movable in an axial direction, include a lining and a back plate supporting a back surface of the lining. The back plate includes a clip insertion portion where part of a pad clip is inserted in the axial direction, at an intermediate portion of a radially outer side portion in a circumferential direction, includes pin insertion portions where the pins are respectively inserted in the axial direction, at both sides of the radially outer side portion in the circumferential direction with the clip insertion portion located therebetween. The clip insertion portion includes, on a radially outer side portion of an inner peripheral surface thereof, a pressed surface where a pressing force directed radially outward is applied from the pad clip.

A disc brake device in which a moment acts on a pad in a direction in which a rotation-in side portion is pushed up toward a radially outer side during braking, including the pad including a pin insertion portion and a clip insertion portion, a pad support member, including a pin inserted into the pin insertion portion in an axial direction, and supporting the pad so that the pad is movable in the axial direction, and a pad clip, including a pad pressing portion inserted into the clip insertion portion in the axial direction, and configured to press the pad radially outward. The pad clip is configured to apply a pressing force to the pad so that a radially inner side portion of an inner peripheral surface of the pin insertion portion is pressed against a radially inner side portion of the pin.

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).

Technologies are described for a durable low friction coating (DLFC), which may be manufactured by mixing a binder, a filler, and one or more additives in liquid form, rolling the liquid mixture onto a coil material and curing for subsequent cutting and stamping. The DLFC may be used to coat an abutment clip or a brake shim directly onto a metal substrate or over an elastomer layer. Water-based binders may be used for environmentally friendly brake systems. In some examples, the binder in the DLFC may be in a range from at least 70 weight % to less than 95 weight %, the filler in a range from at least 1 weight % to less than 15 weight %, and the additives in a range from at least 0.2 weight % to less than 5 weight %.

A disc brake includes a brake caliper that engages over a brake disc and is designed as a sliding caliper. The disc brake has two brake pads which are located in the brake caliper, can be moved in opposite directions and each of which has a pad backing plate with a friction lining secured thereon. An action-side or application-side brake pad of the two brake pads can be pressed against the brake disc by a brake application device with the aid of at least one brake plunger. The brake also includes at least one restoring device, by which the brake caliper can be returned after a displacement and release of the brakes caused by a braking action. The restoring device has a spreading device which engages on the brake pads lying opposite one another and which acts with an identical force in opposition to the respective application direction. The spreading device includes spring-loaded spreading elements, each engaging on its respective pad backing plate. The spreading device is located in the central opening and the spreading elements engage directly or indirectly, outside the friction linings, on at least two contact regions of the brake pads, the regions facing each other at a distance from the center. Each contact region has a contact surface and a support surface, on which surfaces the spreading elements are movably located.

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.
