Rougier reworked a limited quantity of his 1913/14 Turcat-Méry chassis including adding 4-wheel brakes using Henri Perrot's latest drum/shoe brake design. In June 1919 Talbot obtained a license for the braking system. Negotiations took place in 1920 with Renault, but were unsuccessful. However, at the 1920 Motor Show, Henri Perrot demonstrated his brakes on a Renault vehicle resulting in a license being taken up by them in 1921. By 1925, more than fifty car brands around the world were using the braking system. At the 1924 24 Hours of Le Mans the first three cars (1st Bentley 3 Litre, 2nd and 3rd Lorraine-Dietrich B3-6) were all equipped with Perrot brakes. Bendix Corporation In 1924, after meeting at a European auto show, Vincent Hugo Bendix acquired the license to manufacture Perrot's shoe-brake patents and set up the Bendix Corporation with a factory in South Bend, Indiana. Later life Henri Perrot retired in 1949 from Bendix. He remained as a consulting engineer for the French branch of Lockheed in Saint-Ouen and also Ame du Ferodo. He was president of the Society of Automotive Engineers from 1950 to 1953 and became a chevalier of the Order of the Legion of Honour on 13 February 1949 and commander of the Spanish Civil Merite in October 1952. In 1956, he co-authored the book "The Braking of Motor Vehicles on the Road" published by Eyrolles in Paris. He died in 1961 in Monte Carlo.
