Power brakes on automobiles started to be common in the late 40s but was mostly found on more expensive cars. By the 60s it was common on all cars. This one may shock you. The very first power brakes were found on a French car in 1919. The first car to be equipped with a vacuum-operated power booster similar to those we have today was the 1928 Pierce-Arrow. It used vacuum from the inlet manifold to reduce the physical effort needed to apply brakes. Vacuum boosters from then to now have similar designs.
