The disclosure relates to a wheel speed sensor comprising a sensor element, which has a rotation detection element for electromagnetic detection of a speed of a wheel, in particular of a motor vehicle, and a sensor housing enclosing the rotation detection element and a fastening element, which has a fastening opening for vehicle-side fastening of the wheel speed sensor. The sensor element is enclosed by a guide sleeve that guides and/or aligns and/or positions the rotation detection element, wherein the guide sleeve is detachably connected to the sensor element and fixable inside a receptacle of the fastening element.

Wheel speed sensor

In the case of a method for operating a brake system in a vehicle, preferably a service brake system, in particular in a motor vehicle, it is first established whether the vehicle is stationary. If it is established that the vehicle is stationary, it is thereafter detected that the actuating member is actuated by the driver in order to leave the vehicle in the stationary condition. If it is established that the actuating member is actuated while the vehicle is stationary, a signal is generated at least to initiate the temporary under-supply of service brake medium to the operating members.

Method for operating a brake system in a stationary vehicle

The invention relates to a method for operating a brake device, in particular of a motor vehicle, wherein the brake device comprises a service brake and a mechanical parking brake, wherein the parking brake can be actuated by means of a mechanical actuating element, comprising at least the steps of establishing that the actuating element has been moved from an idle position into a position of use, simultaneously controlling a pressure-increasing element, so that a hydraulic pressure is generated, which hydraulic pressure acts on a brake element that is common with the holding element, blocking the common brake element of the service brake and the parking brake with a mechanical block of the mechanical parking brake.
