Abstract
A pneumatic brake system for use with an additional brake including a by-pass valve in parallel to a shut-off valve. The by-pass valve is opened only during an actuating or controlling of the pneumatic brake which exceeds a control range and opens up the passage through the brake pressure line irrespective of the switching condition of the shut-off valve. The connection of the brake cylinder line section of the brake pressure line with the atmosphere by the shut-off valve is at least choked when the by-pass valve is opened up.
