The disclosure relates to the technical field of vehicle accessories, and particularly provides a brake for a vehicle and a vehicle. The disclosure aims at solving the problem that existing brakes for a vehicle usually cannot overcome low-frequency stubborn noise generated by a caliper structure in the brake in a braking process. For this purpose, the brake for a vehicle according to the disclosure comprises a first caliper body and a second caliper body, wherein the first caliper body and the second caliper body are provided with a first friction disc and a second friction disc respectively, a brake disc is arranged between the first friction disc and the second friction disc, and the first friction disc and the second friction disc are each further provided with at least one mass block, so as to quickly reduce low-frequency operating noise of the brake, thereby fundamentally eliminating braking noise, and then solving the problem that the existing brakes for a vehicle usually cannot overcome low-frequency stubborn noise generated by a caliper structure in the brake in a braking process.

The brake pad for a disk brake includes a lining and a plate. The lining includes:—a friction face and a fastening face;—a rear edge;—an inner edge and an outer edge; and—a collection groove extending into the inner edge or outer edge. The plate has a hole, the hole being connected to a vacuum source via communication element. The lining has a rear region including the rear edge and the collection groove, and a chamfered portion such that an area of a friction surface of the rear region increases when a thickness of the rear region decreases, the collection groove being located at a distance from a free surface of the chamfered portion and having a cross-section which extends obliquely towards the free surface of the chamfered portion.

A brake adjusting device is mountable to a frame and a rotary disc of a cable reel and includes a rotary knob mounted to an outside surface of the frame. A first pad is arranged between the frame and the rotary disc and is coupled to the rotary knob for synchronous rotation therewith and includes pushing parts in the form of slope. A second pad is arranged between the first pad and the rotary disc and is provided, on two opposite surfaces thereof, with first and second slope sections and friction plates. The rotary knob is operable to rotate the first pad for causing the pushing parts to press against first and second slope sections in order to move the second pad toward the rotary disc and causing the friction plates to get into tight engagement with the rotary disc to result in a braking effect.

A brake caliper arrangement includes a housing, a restoring device, a first brake lining arrangement and a second brake lining arrangement. The first brake lining arrangement and the second brake lining arrangement can be moved relative to one another from a respective starting position with a reduction of an initial spacing which exists between them. The restoring device includes first and second restoring elements. The first restoring element may prestress the first brake lining arrangement into its starting position, while the second restoring element may prestress the second brake lining arrangement into its starting position. The first and/or second restoring elements may be supported, on both sides of a central region of the brake lining arrangement, on the associated brake lining arrangement. The first and/or second restoring elements may be twisted elastically at least in sections in order to generate the prestress.
