Hydraulic Systems Hydraulic Systems use liquids to make pressure in an enclosed space. They multiply pressure by applying force to a small area, which is then moved to another part of the enclosed fluid, which applies force to a larger area. Types of Hydraulic Systems include lifts and car breaks. These systems are very durable and reliable, since they use liquid and there is nothing to break or jam. (Jones)

Hydraulic Brakes Hydraulic Breaks are found in car breaks. When the break pedal is pressed, it pushes a small piston. "The piston exerts pressure on the break fluid." (Jones 94) The pressure is spread through the break fluid to the other, larger pistons, which push on a break pad. The break pad presses against the break disc, and the friction generated stops the wheel's motion. Through the amplification of force, someone can stop a big car with just the push of the break pedal. (Jones) media type="custom" key="7984378"
