Abstract: In order to avoid oscillations and brake screeching associated with such oscillations, a brake caliper is provided with a reinforcing element. The reinforcing element is formed with a C-shaped profile element that is connected to the brake caliper on the underside of the housing of said brake caliper. The reinforcing element can also be configured in order to hold the brake pads and linings and therefore relieve the housing of the braking torque.

Abstract: In order to prevent squealing of a disk brake, the disk brake has a brake disk with friction rings having locally weakening section moduli which detune corresponding to the natural oscillation mode. As a result, the natural oscillation mode of the brake disk is changed to such an extent that brake squealing is avoided.

Abstract: A combined disk and drum brake has two friction rings and an inside shoe brake, where the inside friction ring exhibits an annular channel. This annular channel serves to collect and drain water or water droplets entering into the brake disk, so that this liquid is drained over a gap between the outer friction ring and a shielding plate. Furthermore, the air guide channel is designed as a separate, water-draining channel in the brake disk.

Abstract: An internally ventilated brake disk has two friction rings and an inside shoe brake, in the interior friction ring. A ring groove is provided which, in its base, has passage openings to air guiding ducts between the friction rings of the brake disk. The ring groove is bounded laterally by a water collecting surface and on the opposite side by a water draining surface, in which case these two surfaces are inclined with respect to an exterior groove opening such that this groove opening is narrowed. The water collecting surface is arranged in an intended manner with respect to a wall of the air guiding duct. This indentation is used for collecting splashing water and removing the splashing water by way of the air guiding duct or a space between the friction ring and the shielding metal plate to the outside.

Abstract: A brake arrangement, especially a disk brake for vehicles which includes brake pads guided in a brake caliper on both sides of a brake disk that are operatively connected with hydraulically actuatable actuating pistons. Each actuating piston includes a bore directed toward the brake pad in which an insert member is arranged that includes an element covering the piston end surface and is held with play with respect to the inner circumferential and bottom surfaces of the bore. The element consists of a plate-shaped intermediate inset member which is connected with the two insert members and is provided on its surface facing the brake pad with a friction-increasing layer.
