 The Kunze-Knorr brake brought together the ideas of Prussian senior surveyor, Bruno Kunze (1854–1935), and preparatory work by the founder of Knorr-Bremse, Georg Knorr (1859–1911).It was the first, continuous, compressed-air brake that, even on long goods trains, enabled the brake force not only to be applied gradually, but also released again gradually.By combining a single-stage and a two-stage brake cylinder with a compound brake a significant increase in brake effort was achieved.
