Abstract: A brake monitoring device for sensing a value which reflects the actuation and/or release stroke of a thrust element of a brake actuating mechanism, which thrust element is guided in a housing of a brake caliper. The thrust element acts via a brake lining onto a brake disc by a lever. A sensor is configured to detect variations of a physical quantity at least one component of the brake actuating mechanism. The sensor and component are arranged such that relative movement between them generates constantly repeating variations of the physical quantity along a path. The path is formed between the component of the thrust element and the sensor in axial direction of the thrust element by means of a linear extension from the end of the thrust element facing the brake disc, axially away from the brake disc.

Abstract: A drum brake assembly with a camshaft and a wear monitoring device for measurement of the wear status, the wear monitoring device and the camshaft including alignment mechanisms which enable and ensure that only one particular angular position between the camshaft and a rotating element of the wear monitoring device is possible.

Abstract: A monitoring device for detecting a value indicative of the actuation stroke and/or release stroke of a thrust element of a brake actuating mechanism, the thrust element being actuated by a lever of the brake actuating mechanism, including a sensor for sensing variations in a physical property of at least one part of the brake actuating mechanism, whereby the sensor and the part of the brake actuating mechanism are arranged so that by the relative movement between the part of the brake actuating mechanism and the sensor repeated variations in the physical property along a path of the relative movement are created and sensed. The path is formed between the lever and a stationary part being adjacent to the lever. The invention is directed both to drum brakes and to disc brakes.
