CAR CAR H Bauer Publishing 1887 What’s that smell? Karl Benz, father of the motor car, releases his second threewheeled Motorwagen. With faultless logic, he calls it the model number 2. The first car had no brakes. Number 2 boasts leather brake shoes on the rear wheels. On the downside, they barely work; on the upside, any cobbler can service them. Handy. 1929 Drums being drums (generally awful), Bentley works tirelessly to coax some power and bite from its brakes, motivated by the unarguable truth that its cars are significantly heavier and more powerful than most. The Blower racer, with its 4.5-litre supercharged engine, gets Bentley’s self-wrapping drums – under braking the axles roll on their springs, pulling the brakes on harder. They’re good: for drums. Blower Bentley had great drums – but they were still drums. Panic! 1942 The Tiger rolls out of Nazi factories and onto the battlefields of the Second World War. Terrifying to behold, let alone fight, it boasts so many unfair advantages it’s a blessing fewer than 1400 are built. The disc brakes are footoperated and they both slow the 50-tonne behemoth and, with each disc brake able to work independently, function as emergency steering system. 1951 We’re gonna need a bigger brake BRM rolls out the Type 15 – a machine to have even the bravest drivers reaching for their teddy bears. The engine, a supercharged 1.5-litre V16 (more power than the sun; filthy noise) demands equally potent brakes, so BRM trades the missile’s threeshoes-percorner Girling drums for discs – a first on a Formula 1 car. 1946 Dunlop, having accelerated its brake technology via the catalyst of war, files a patent on a meaty disc brake for automotive use. It then sets about developing the concept, subsequently jumping into bed with Jaguar, whose new straight-six engine (developed during the mid-’40s) is so powerful it renders even decent drums obsolete. Jaguar’s evolved disc brakes will arrive in style on the Le Mans-winning C-Type in 1953, the first time the race is won at an average speed north of 100mph. 2019 For decades it was simple: engine makes you go, brakes help you stop. Then electrification means imperceptibly blending hydraulic braking with regenerative charging – challenging, to say the least. Honda spends years getting it right on the hybrid NSX, then Porsche takes EV braking to the next level with the Taycan: the regen system’s so powerful 90 per cent of braking’s achieved without the discs. 1955 A decade after the end of the war and, bejewelled with many technologies the conflict had accelerated, Citroën defines the modern automobile with the incomparably beautiful DS. Production disc brakes are but a fraction of its engineering wonder, the calipers squeezed by pressure from the car’s onboard hydraulic system.
