Abstract
A braking device for a vehicle comprises a main brake cylinder, which provides, in response to the actuation thereof, an operating brake pressure in at least one operating brake circuit for the actuation of an operating brake. A hydraulic fluid pressure intake is connected to a hydraulic circuit, which contains a hydraulic fluid having a built-up hydraulic circuit pressure. Through the hydraulic fluid pressure intake, the hydraulic fluid is provided at the hydraulic circuit pressure. The braking device further comprises a valve device, which actively controls a main brake cylinder actuation pressure and/or a parking brake release pressure by means of the hydraulic fluid that is provided. The main brake cylinder is actuated by means of the main brake cylinder actuation pressure for an active brake engagement. Alternatively or additionally, a parking brake is hydraulically released by means of the parking brake release pressure.
