Automotive A typical automobile braking system comprises of a braking device having different components, which are used for slowing or stopping down a vehicle. More precisely, these devices decrease or stop the speed of a moving or rotating body by absorbing kinetic energy mechanically or electrically. They are widely used in motor vehicles, buses, trucks, trains, airplanes, and other types of automobiles. The worldwide automobile industry is currently witnessing rapid innovative developments day by day. According to a research study by Frost & Sullivan, there is likelihood that after 2010, the global automotive industry will start using brake-by-wire systems instead of hydraulic braking systems. The various technologies such as electro mechanical braking system and the electronic wedges brake are soon going to replace the older braking systems. With the help of these brake-by-wire systems, automobile drivers will be having more control on their vehicles particularly in case of sheer emergency.
