Abstract: A device (1) and a method are provided for determining the oscillatory behavior of a brake lining (3) for a motor vehicle. The device (1) has a mounting device (2) for mounting a brake lining (3) and a securing device (6) for securing a brake disk model (7) assigned to the brake lining (3) so that the brake lining (3) can be brought to bear with the brake disk model (7) against a contact face (8). A pretensioning device (9) is coupled to the mounting device (2) and/or to the securing device (6) so that the brake lining (3) can be pressed against the brake disk model (7) with a pressure force (10, 10?) predetermined in terms of absolute value and direction. An excitation device (13, 13?) is provided for exciting oscillations of the brake disk model (7) and/or the brake lining (3).

Abstract: A piston (30) for a cylinder and piston unit (24) of a disc brake (10), with a novel capability of damping the vibrations induced by a braking action, comprising a body (32) and a head (34) designed to come into contact with a pad (20) to act on a braking strip (13) of a disc (12), a damping element provided between the head (34) and the body (32) of the piston (30), in which the head (34) and the body (32) comprise, respectively, a stem (62) and a recess (41) for the stem (62), forming a gap (64) for the damping element.

Abstract: In a method for determining the state of a motor vehicle brake, particularly the brake-lining state or the brake-lining thickness, a temperature sensor is arranged in the brake lining of the motor vehicle brake, and the temperature detected by the sensor is used to determine the brake state. In addition to a first temperature value, at least one second temperature value detected after the first temperature value and the time duration between the detection time points of the two temperature values are employed. The brake state is determined based on an evaluation of a time profile of temperature values sensed by said sensor.

Abstract: The invention relates to a method for modifying and adjusting the braking force in a hydraulic brake system in a vehicle, whereby the pedal control exercised by the driver is measured and is converted via a predefined function into braking pressure to be produced in a wheel brake device, said pressure corresponding to a deceleration of the vehicle. In order to increase the braking safety, the braking pressure or the variable correlating with the braking pressure can be individually manipulated as a function of the pedal control within a section of said pedal control between the initial starting point and maximum pedal control point.

Abstract: A servo friction brake which includes a carrier, and at least one friction lining which is supported on the carrier and interacts with at least one friction surface, and at least one device for actuating the friction lining. In order to considerably reduce the sensitivity of the friction brake to coefficient of friction and to achieve high servo effect values, especially in the range close to the locking limit, a mechanism which permits varying the servo effect during operation of the brake.
