The guide pin assembly may include a resilient member that extends between a bushing and a sleeve. The sleeve may be mounted to the brake carrier. The brake caliper may be slidable along the bushing.

Disclosed is a friction set for a railway disk brake system for railway rolling stock including: a shoe holder including a receiving slideway; a friction shoe including a brake pad and a profiled shape configured for being slid into the receiving slideway, where the friction shoe includes a pneumatic conduit connecting a first space delimited by a first surface of the friction shoe to a second space delimited by a second opposite surface the friction shoe; a through hole arranged in the shoe holder and laid out so as to be facing the pneumatic conduit; and a pneumatic connector mounted on the shoe holder, pneumatically connected with the through hole, extending away from the friction shoe and rotationally mobile relative to the shoe holder, around an axis perpendicular to a main plane of the shoe holder.

This disc brake includes a first shim that has a first flat plate portion and claw portions curved from an outer edge side of the first flat plate portion and attached to an outer circumferential surface of a rear plate; and a second shim that has a second flat plate portion disposed in a manner of being sandwiched between the first flat plate portion and the rear plate, and a bent portion curved from an outer edge side of the second flat plate portion to the first flat plate portion side. Relative movement of the second shim with respect to the first shim on a plane parallel to the second flat plate portion is restricted. A leading end portion of the bent portion of the second shim is disposed within a projection plane of a largest flat surface portion of the rear plate in a disc axial direction.

The application relates to a brake pad assembly for a disk brake system. In addition, the application relates to a disk brake system. The proposed brake pad assembly comprises a back plate having a front side for facing a brake disk of the disk brake system and a back side. A friction layer is arranged at the front side of the back plate for contacting a friction surface the brake disk. Further, a shim is arranged on the back side of the back plate. The shim has a front side facing the back plate. Further, an adhesive layer is arranged between the back side of the back plate and the front side of the shim. The shim further comprises a metal layer having a wave-shaped surface on its front side.

A disk brake apparatus may include a caliper body installed on the outer circumference of a disk; a piston member installed in the caliper body, and moved by hydraulic pressure; a brake pad pressed toward the disk by the piston member; and a shim plate installed between the piston member and the brake pad, formed in a plate shape, and abutting on a piston contact part installed on a surface of the piston member, facing the brake pad, the shim plate may include a cover shim brought into contact with the piston contact part; and a pad shim stacked on a surface of the cover shim, facing the brake pad, and including an opening formed through a region which overlaps at least a part of the piston contact part.

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 brake assembly having a guide pin assembly that slidably couples a brake caliper to a brake carrier. The guide pin assembly may include a resilient member that extends between a bushing and a sleeve. The sleeve may be mounted to the brake carrier. The brake caliper may be slidable along the bushing.

A brake pad for a vehicle disk brake assembly includes a backing plate configured to support a brake lining. A plurality of openings extend through the backing plate to define retaining members. A shim includes a base and tabs extending into the openings to secure the shim to the backing plate. Each tab includes a first portion extending away from the base and a curved second portion extending from the first portion back towards the base.

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.

The invention relates to a shim and to a brake pad assembly for a vehicle disc brake, wherein the vehicle disc brake comprises a brake disc that is configured to rotate about a rotation axis and the brake pad assembly comprises: a backplate that is configured to carry a friction material lining at its front face for contacting the brake disc; a shim that is arranged at a rear face of the backplate;
wherein the shim has a radially upper edge and a radially lower edge and the radially upper edge and the radially lower edge are connected by two opposite side portions of the shim;
wherein the shim has at least one laterally protruding heat dissipation portion that is comprised by one of the side portions and that protrudes past a side edge of the backplate.
