A friction lining assembly having a backing plate and a sheet metal restoring spring fixed thereto, for a partially lined sliding-caliper type disk brake having a brake holder fixed with respect to the vehicle, on which friction lining assemblies arranged on both sides of a brake disk are slidably guided. A housing, which extends over the brake disk and the friction lining assemblies, is slidably mounted on the brake holder. The restoring spring is clamped axially between the brake holder and the friction lining assembly by at least one spring leg and applies a release clearance to the friction lining assembly. The spring leg extends over a hammer-head-shaped claw of the backing plate. The spring leg is plastically deformable in a defined manner under braking actuation as a result of a reduction in the friction-material thickness in order to impose a constantly dimensioned release clearance on the friction lining assembly.

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.

A floating disc brake includes a yoke supported to the support in an axially movable manner, the yoke including a pad support portion that supports an outer pad on an axially outer side of the outer pad. The outer pad includes, on its axially outer surface, a pair of pad-side engagement portions formed of an elastic material. The pad support portion has a support hole that is open on at least an axially inner surface of the pad support portion, and the support hole is provided with a pair of yoke-side engagement portions on inner side surfaces of the support hole that face each other in a circumferential direction. The pair of pad-side engagement portions and the pair of yoke-side engagement portions are concavo-convex engaged with each other in the circumferential direction.

A device for supporting and guiding a brake pad backplate and a brake pad arranged thereon in a pad slot of a disc brake, including a restoring device formed by two separately acting restoring elements. One restoring element is formed by a wire spring which serves to restore the lower portion of the brake pad backplate, while the other restoring element is formed by a pad hold-down spring which is capable of restoring the upper portion of the brake pad backplate.

A piston configured for use in a brake system is disclosed. The piston can comprise: a body; and a footing; the footing positioned adjacent an end of the body, and having a recess that receives a central portion of the end; during operation of the brake system, the footing extends along a brake pad, and is configured to exert force on the brake pad during actuation of the disk brake system; and the footing having a face configured to contact the brake pad, the face having a length and a width, wherein the length is longer than an outside width of the body, and the length is greater than the width, and/or the face having a cross-sectional area normal to a direction of travel of the piston that is larger than a cross-sectional area of the piston body that is normal to the direction of travel of the piston.

Disc brake comprising a yoke, at least one first brake pad mounted so as to slide within the yoke, the first brake pad comprising a pad support and a friction material, a caliper comprising at least one piston mounted so as to slide within the caliper in such a way as to move the first brake pad in relation to the yoke, at least one actuator configured to move the piston axially, and a separators device inserted between the piston and the first brake pad forming an equaliser so as to distribute the thrust force exerted by the piston onto at least two zones of the first brake pad, at least partially distinct from the projection of the piston onto the first brake pad.

A load lowering descent controller having a fixed cylindrical body or capstan about which a rope or cable is turned. The descent controller allows for lowering of the load at a controlled rate by adjusting the amount of friction between the controller and the rope or cable as a function of rope or cable turning and relative contact with rope or cable engagement surfaces in the controller. The fixed cylindrical body or capstan is surrounded by a vented sleeve to prevent the rope from becoming heated and to prevent the user from being injured.

The invention relates to a brake pad assembly (10) for a vehicle disc brake (11), the brake pad assembly (10) comprising a lining carrier (12) and a brake lining layer (14) attached to the lining carrier (12), wherein the lining carrier (12) has a first portion and a second portion which are connected by at least one connecting portion (20) forming at least part of a side face (21) of the lining carrier (12), wherein the connecting portion (20) is elastically deformable upon braking.

A brake pad retracting device is disclosed. An example vehicle braking system comprising a rotor, and a caliper including a brake pad slidably engaged with a guide pin, and a coil spring through which the guide pin extends, the coil spring having a first end and a second end, the first end having a first inner diameter sized to enable the first end to move freely over a surface of the guide pin, the first end to engage the brake pad to urge the brake pad away from the rotor, and the second end having a second inner diameter sized to frictionally engage the surface of the guide pin, the first inner diameter greater than the second inner diameter.

An elastic return spring for axially returning a brake pad of an automotive disc brake from an active position to an inactive position, the spring being intended to be interposed between the brake pad and a fixed support, with an elastic deformation portion, a carrier portion arranged to be fastened to the fixed support of the disc brake, and a pad portion. The carrier portion includes a support part and a connection part which including at least one connection fold arranged and configured to bear on an anchoring part of the fixed support and to cooperate with said anchoring part to avoid any lifting of the connection part.
