Abstract

A brake device for motor vehicles has at least two hydraulic brake circuits which are directly connected to a master brake cylinder, as well as an additional brake circuit, which is able to be actuated via a control device, independently of the master brake cylinder. Because of the separate hydraulic brake circuits in the region of the front axle, redundancy is provided, while the third brake circuit, that is able to be actuated independently of the master brake cylinder and typically acts on the rear wheels, during automatic actuation, permits taking into account a braking effect by additional active assemblies, such as a driven generator.
