The History of Brake Technology
From the moment people invented transportation system, brakes were essential. At first, there were horse drawn carriages but soon other mechanical forms or transportation vehicles replaced them and the moving speed improved greatly. In consequence, braking machinery has had to keep up with a view to give motorists a higher standard in protection. Today, we have different kinds of brakes in our vehicles, drum brakes, disc brakes, anti-lock brakes and many more. The choices are many and it’s essential that we know a bit more about the distinctions between different brakes.
Most of the car brakes used in earlier models were a kind of drum brakes. A drum brake functions with a drum that is wrapped around an axle. When force is applied, typically through a metal band, the drum would compress all-around the axle, creating slowness of motion. The difficulty with this kind of brake was that it’d slip when wet. This contributed to the formation of the disc brake.
Disc brakes have a group of shoes called brake pads which push against a disc which is attached with the wheel and spins around with it. You may employ this brake by pneumatic, electromagnetic, mechanical or hydraulic power. A disc brake is commonly placed inside the wheel, following the tire. Since it was free of the difficulty drum brakes had and provided superior performance in slowing down the automobile, they soon become the first choice for all vehicles. The brake pads of a disc brake are usually crafted from ceramic, asbestos and a few other compounds to make them durable and robust.
As disc brakes became an industry benchmark, there still remained the problem of the brakes locking up. As a result, anti-lock brakes were invented. Anti-lock brake system includes valves, speed sensors, pumps plus a controller. These things involuntarily alter the brake pressure when stopping on slippery surfaces. Today we have computer controlled anti-lock brake system. Each wheel has got a sensor which determines the requirement of braking pressure. As a result of their near-perfect execution, anti-lock brake systems now are an essential security item in all modern automobiles.
Brakes should be checked frequently, it doesn’t matter what type of brake you have, if it’s not in good condition you can get in serious trouble. To ensure your car brakes are working fine, you must often get the brakes checked by trained car mechanics. They be familiar with the functions of different kinds of brakes and can perform any servicing that the brakes may need to keep you safe and secured on the road.
