This disk brake includes an attachment member that has support portions movably supporting a pair of brake pads, and a caliper that pressurizes the brake pads against a disk. The attachment member has outer circumferential frame portions, a coupling beam portion, and support main body portions. The outer circumferential frame portions extend in a disk circumferential direction so as to cover the disk while straddling the disk. The coupling beam portion couples the support portions to each other. The support main body portions form the support portions. The outer frame constituting portions constitute the outer frames of the support main body portions. Positions of disk-axially outward side end surfaces in a disk axial direction are the same as positions of the disk-axially outward side end surfaces of the caliper or on sides outward in the disk axial direction.

A fixing structure of an automobile caliper cover is used for fixing a caliper cover body to an automobile caliper. The fixing structure includes a first fixing member and a second fixing member. The first fixing member includes a connection bracket, a first bent portion fixedly connected to the connection bracket, and a second bent portion cooperating with the first bent portion and fixing the connection bracket to the car caliper; and the first bent portion and the second bent portion are fixedly connected; and/or the second fixing member includes a connection bracket and a fixing buckle fixedly connected to the connection bracket, in which the fixing buckle is used for fixing the connection bracket to the automobile caliper. The connection bracket has at least one bent portion to enhance a strength of the connection bracket and facilitate fastening installation of the connection bracket.

The present invention relates to a commercial vehicle disc brake caliper assembly comprising a caliper body and a left guide pin component, right guide pin component, the main adjuster mechanism assembly, the driven adjuster unit are all mounted on the caliper body. The adjuster mechanism assembly adopts a gear cluth structure with anti-overload function; the driven adjuster unit adopts a circlip structure; the main adjuster assembly and the driven adjuster unit is connected by sprocket chain. The bottom of the main adjuster assembly and the bottom of the driven adjuster unit are connected to the three thread calibration bolt, which connected with bridage, the bridage are arranged inside of the brake caliper. The invention overcomes the problems which may occur during brakeing, such as uneven braking force, failure of clearance adjustment, deformation of adjuster mechanism, failure of braking, etc.

A heat-dissipating car caliper cover comprising a cover body and a fixing member for fixing the cover body to a car caliper, wherein a first arc-shaped side plate is provided on an outer side of the cover body, a second arc-shaped side plate is provided on an inner side of the cover body, the fixing member is provided on the first arc-shaped side plate, a heat transmission assembly is provided on the first arc-shaped side plate, and the heat transmission assembly comprises an elastic pressing sheet and a silicone sheet provided on the elastic pressing sheet; and when the cover body is fixed to the car caliper, the elastic pressing sheet can contact the silicone sheet with a pump body outer side wall of the car caliper, and conducts heat to the cover body for heat dissipation.

A brake dust cover is disposed between a non-rotating body rotatably supporting an axle and a disc rotor rotating together with the axle so as to cover the disc rotor from an inner side in a vehicle width direction. The brake dust cover includes a first plate-like member having a C-shape in which a part of a circular ring is cut out, and a second plate-like member coupled to the first plate-like member. The second plate-like member includes a fixed portion fixed to the non-rotating body, and a plurality of support portions extending radially from the fixed portion. The first plate-like member is coupled to the second plate-like member to overlap the support portions such that an opening portion is formed between an inner edge of the first plate-like member and an outer edge of the fixed portion of the second plate-like member when viewed in the vehicle width direction.

A braking system for safely collecting brake dust produced by operation of a braking mechanism. The braking system comprises a collector apparatus coupled with a braking mechanism. The collector apparatus is able to include a shroud that surrounds the braking mechanism and a catch element coupled with the shroud for collecting brake dust exiting the shroud. As a result, when coupled with the braking mechanism, the collector apparatus is able to ensure that most or all brake dust, such as copper or other particles from the braking mechanism that break off from the breaking mechanism during operation of the braking mechanism, are removed from the braking mechanism and collected by the filter/catch of the collector mechanism.

A brake dust particle filter for a brake caliper of a disc brake assembly, wherein the brake caliper comprises a lining inspection opening, closes in a mounted state thereof the lining inspection opening at least partially with precise fit. The brake dust particle filter is provided with a filter medium support that supports a filter medium. A brake caliper provided with the brake dust particle filter in the lining inspection opening is arranged across the brake disc of the disc brake assembly.
