Abstract: The present invention relates to a braking device and to a braking system, each having a master brake cylinder (10) having at least one first pressure chamber (12) that is subdivided or is able to be subdivided at least into a first partial volume (12a) and a second partial volume (12b), which are hydraulically connectable or connected to a brake fluid reservoir (24), a first brake circuit (28) being hydraulically connectable or connected to the first partial volume (12a), and having a valve device (38) that is mechanically designed in such a way that a pressure buildup up to a mechanically specified limit pressure may be brought about in the second partial volume (12b), brake fluid being transferable at least into the first brake circuit (28) via at least one subcomponent (38a) of the valve device (38), and an exceeding of the limit pressure in the second partial volume (12b) being prevented.

Abstract: A hydraulic block of a hydraulic multi-circuit vehicle braking system having braking force regulation includes an installation space for a hydraulic reservoir of the vehicle braking system that is isolated from a braking circuit, for example by closing a connecting line using a pressed-in ball. The installation space is connected to another braking circuit via an additional bore, wherein a larger storage volume is available to the braking circuit as a result. The necessary changes to the hydraulic block are small.
