context_page_description: Henri Perrot was a French engineer who was one of the pioneers of the automobile industry from the late nineteenth and early twentieth centuries. He holds numerous patents in the field of automotive drum/shoe braking.
context_section_description: In 1919, Delage licensed the Perrot braking system and fitted it to their 6-cylinder chassis, it was also used by Hispano-Suiza on a car designed by Marc Birkigt with a mechanical servo and Henri 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.
