How Automobile Brake Technology Developed
June 15th, 2011From the time people first began using transportation vehicles, the necessity for brakes has existed. As motorized automobiles began to replace horse drawn carriages and other types of transportation, speeds have increased. Because of this, braking machinery has had to carry on with a view to give drivers a higher standard in safety. From drum brakes and disc-brakes to anti-lock braking systems, the technology we have in our everyday travels presents several options and it is essential to know the difference.
Most of the car brakes used in earlier models were a type of drum brakes. A drum brake functions with a drum which is wrapped around an axle. When the drum brake is applied, typically via a metal band, it pressurized the drum. The drum would then compress all-around the axle creating friction to slow the motion. However, this kind of brakes did not do well when wet. Because of this failure of drum brakes, disc brakes were invented.
Disc brakes have a set of shoes known as brake pads that press against a disc that is attached with the wheel and spins with it. This could be brought on by pneumatic, hydraulic, mechanical, or electromagnetic power. A disc brake is usually located inside the wheel, following the tire. As a result of increases in resources manufacturing technology, disc brakes have become a superior choice than drum brakes. Disc brakes utilize brake pads made of asbestos, ceramics, and a range of other compounds, presenting them a longer usage life.
By the way, disc brakes weren’t free of problems, brake locking up at times caused trouble. Consequently, anti-lock brake systems were designed. Anti-lock braking systems function by using speed sensors, pumps, valves, and a controller to automatically adjust the brake pressure at times stopping on slippery roads. Modern day anti-lock brake systems are computer controlled, with every wheel with a sensor which finds out the required braking pressure. Because of their near-perfect execution, anti-lock brake systems have become an essential security item in all modern automobiles.
Brakes must be checked often, no matter what kind of brake you’ve, if it is not in good condition you might get in big trouble. To make sure the car brakes are working well, you must often get the brakes checked by skilled car mechanics. Mechanics know how different brake systems perform and can advise any needed service to keep you safe on the road.
