Why Detroit COULDN'T LET GO of Vacuum Brake Boosters!

What if the braking system in almost every car you’ve ever driven was invented by two men who weren’t even trying to build car brakes? In the 1920s, aircraft engineer Victor Kliesrath and racer-engineer Caleb Bragg adapted vacuum technology to solve one of Detroit’s biggest problems: heavy cars were becoming brutally difficult to stop. Their invention became the vacuum brake booster, transforming pedal effort into powerful braking through nothing more than atmospheric pressure and engine vacuum. From Pierce-Arrow to Bendix, the system became nearly universal—until turbo engines, diesels, and especially EVs made vacuum obsolete. Now, one of automotive history’s greatest hidden inventions is quietly disappearing. #CarHistory #BrakeBooster #AutomotiveHistory #ClassicCars #Engineering #musclecarmasters #musclecarmasterschannel 1.
