Abstract
The invention relates to a brake system, comprising at least one piston-cylinder unit for producing a pressure in at least one working chamber, the working chamber being connected to at least one wheel brake via at least one hydraulic line, and the brake system comprising at least one drive device and an actuating device, particularly in the form of a brake pedal, and the drive device during normal operation acting on the at least one first piston of the piston-cylinder unit for building pressure and reducing pressure by way of a first force transmission means, and in the event of failure of the drive device the actuating device acting mechanically on the piston by way of a second force transmission means, wherein the adjustment of the second force transmission means disengages the connection between the first force transmission means and the piston by means of the actuating device.
