American milestone: 1917 · Malcolm Loughead · Santa Barbara, California
Status: Replacement candidate. Final number pending chronology audit.
Why it belongs in America 250
Malcolm Loughead patented a fluid-operated automobile braking system in 1917. Hydraulic pressure allowed braking force to be transmitted more evenly to multiple wheels than many mechanical linkage systems of the period.
Connection to automation
Hydraulic power transmission became fundamental to vehicles and industrial machinery, providing controlled force distribution through fluid pressure.
