Automotive brake system or automobile brake system used in automobiles has come a long way in recent years. The adoption of anti lock brake systems along with the introduction of different brake parts made of carbon fiber, steel, aluminum etc have really provided better stopping performance in comparison with traditional ones. The major manufacturers of auto brake systems in the world are Bendix, Bosch, Delco, Continental Teves, Kelsey-Hayes, Nippondenso, Sumitomo, and Toyota.
Blaise Pascal was a seventeenth-century French mathematician and philosopher who formulated the principle that a change of pressure at one point of a confined fluid is communicated undiminished to all parts of the fluid. In an automobile braking system, the brake lines are filled with just such a 'confined fluid'. When pressure is applied via the brake pedal from a piston in the master cylinder, pressure is transmitted equally to all four brakes.
