A method for supplying vacuum for a pneumatic brake booster for a motor vehicle braking system, using an electromotively-driven displacement type pump assembly. At least one pressure sensor for monitoring a pneumatic pressure is associated with the pump assembly, and electric signals of the pressure sensor are fed to an electronic unit, analyzed, and processed in order to regulate the pressure. A plausibility check of the pressure sensor signal is carried out by a pressure value amplitude being determined, by signal analysis, in the form of a difference between a maximum pressure value and a minimum pressure value within a stroke of the displacement element, and this being compared to a stored comparison value wherein if the pressure value amplitude deviates from the comparison value by a defined amount, the signal of the pressure sensor is then defined as implausible.

A spindle drive has a spindle nut () and a threaded spindle () mounted in a rotationally fixed and axially displaceable manner on a reference body () by way of a linear guide, wherein the axis () of the threaded spindle () is arranged parallel to the longitudinal direction of the linear guide, and wherein the linear guide has a groove () and a guide element () engaging in the groove and comprises an elastic region (&#x2033;), the width of which perpendicular to the longitudinal direction of the linear guide is greater than the maximum groove width in the region used for the linear guide.

A force measuring device for a parking brake of a vehicle has a housing, having a Bowden cable for actuating the parking brake and having a force measuring element for determining the cable force. The Bowden cable is guided through the housing and has first and second stops which are fastened to the Bowden cable, wherein under loading of the Bowden cable, the first stop is fixedly supported on a housing inner side and the opposite, second stop is supported on the force measuring element which is provided between the housing and the second stop, wherein a movement of the second stop is generated corresponding to the loading of the Bowden cable, which movement leads, at the force measuring element, to a corresponding measurement value for the force transmitted by the Bowden cable. The force measuring device is provided for parking brakes for passenger vehicles.
