A unit for detecting a filling level of a liquid in a container. The unit includes at least one float gauge, which carries at least one permanent magnet, and including at least one switching unit, which is actuatable by the permanent magnet and is fastened in or at the container. It is provided that at least one energizable magnetic device for generating a magnetic field is assigned to the switching unit, which, when sufficiently energized, generates a magnetic field, which actuates the switching unit when the switching unit is functional.

A braking method is used for a vehicle that has at least one front wheel and at least one rear wheel. A hydraulically actuatable brake is provided at the front wheel and the rear wheel, and an automatic parking brake is provided at the rear wheel. The braking method enables an optimal brake pressure to be built up as rapidly as possible. In a first step of an initiation phase of the braking method, the front wheel is braked by the hydraulically actuatable brakes and the rear wheel is braked exclusively by the automatic parking brake.
