Power brakes consist of a system of hydraulics used to slow down or stop a motor vehicle. It uses a combination of mechanical components and vacuum assistance to multiply the pressure applied to the brake pedal by the driver into enough force to actuate the brakes and stop the vehicle. By contrast, manual brakes rely solely on the pressure the driver applies to the brake pedal.
A power braking system consists of several distinct components, including the vacuum booster, master cylinder, brake fluid reservoir and lines, and calipers (or drums). Power brakes have been around in some form since the 1920s, and since the late 20th century all cars sold in North America have been equipped with power brakes.
