A vehicle caliper cover set includes a plurality of caliper covers. Each caliper cover includes an inner surface sized and configured to be complementary in shape to an outer surface of one of the plurality of calipers. Each caliper cover further includes an outer surface having a medial portion and a lateral portion positioned in opposed relation to the medial portion. The inner and outer surfaces define a thickness therebetween, with the thickness being between 0.015-0.150 inches. Each caliper cover additionally includes a multi-sided opening extending from the inner surface to the outer surface, with the multi-sided opening being positioned between the medial and lateral portions of the outer surface.

The caliper cover assembly includes a first bracket, a second bracket, and buckles; the first bracket and the second bracket are respectively integrally formed with the caliper cover body; the first bracket and the second bracket are symmetrically disposed, and are respectively provided with an installation hole; the buckles are provided in two; the two buckles are symmetrically and separately disposed on the first bracket and the second bracket, and fixedly connected with the first bracket or the second bracket through bolts passing through the installation holes respectively. Therefore, effects of a stable structure, a thermal conductivity, a convenient installation and a safety in use are achieved.

Brake calipers and rotors for bicycles are described herein. An example brake caliper includes an outboard caliper portion to be disposed inboard of a frame of the bicycle. The outboard caliper portion includes an outboard caliper body and an outboard brake pad that is fixed relative to the outboard caliper body. The brake caliper also includes an inboard caliper portion coupled to the outboard caliper body. The inboard caliper portion is disposed inboard of the outboard caliper portion when the brake caliper is coupled to the bicycle. The inboard caliper portion includes an inboard caliper body and an inboard brake pad that is movable relative to the inboard caliper body.

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 clutch 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 braking, such as uneven braking force, failure of clearance adjustment, deformation of adjuster mechanism, failure of braking, etc.

A brake device including a guide receiving area for connecting to a bearing component, forming a brake device bearing moveable in the direction of a first straight line. The brake device has a brake caliper with a first frictional surface and a first actuation surface, a pressing part being linearly guided along the first straight line relative to the brake caliper. The pressing part has a second frictional surface and a second actuation surface, and the brake device has a spreading element which interacts with the first actuation surface and the second actuation surface. The rotation of the spreading element changes the minimum distance between the frictional surfaces. A movement damping part coupled to the spreading element is designed to damp a translational movement of the spreading element relative to the bearing component in the guide receiving area parallel to the first straight line.

A caliper for an opposed-piston disc brake, includes a pair of bodies provided at two sides of a rotor that rotates with a wheel, each of the bodies including five cylinders. A central cylinder among the five cylinders provided on each of the bodies, which is surrounded by four of the cylinders, has a center which is located in a region on a radially inner side relative to an outer reference circle and on a radially outer side relative to an inner reference line. The outer reference circle passes through a center of a cylinder provided on a radially outermost side among the four of the cylinders and has a center thereof on a center of the rotor. The inner reference line passes through centers of two of the cylinders provided on a radially inner side among the four of the cylinders.

A brake pad retraction spring that includes a coil, first and second biasing arms, and first and second biasing tips. The first and second biasing arms may extend from the center coil. The first and second biasing tips may extend from ends of the first and second biasing arms, respectively.

The invention relates to a multi-part brake caliper for a vehicle disc brake, the brake caliper comprising: a first part comprising a first portion that is arrangeable at a first side face of a brake disc of the vehicle disc brake; a second part that is formed separately from the first part and comprises a second portion that is arrangeable at a second side face of the brake disc; a middle part connecting the first part and the second part; wherein the middle part is connected to at least one of the first part and second part by a rotational joint.
