ABS, also knows as the Anti-lock braking systems, are used for short stops. Usually, when one is stopping short on a slippery rode, they are needed. The road may be slippery due to snow, rain, or ice. When on a slippery surface, most likely ice, the car does not usually move forward, or stop, because the tires have little to no traction due to the wet ice. The Anti-lock Breaking Systems allows for the car to come to a faster stop on ice. It also allows the driver to steer the car while he is coming to a stop. The speed sensors in the ABS inform the system of the cars speed and therefore can detect if the wheel [or car] is entering a situation in which it may lock up. The valves control the pressure of the break by lowering it. On the other hand, the pump raises the pressure of the brake. Inside the car there is a controller, similar to a computer, which controls the speed sensors, the valves, and the pumps. Depending on the number of channels and sensors in the specific system, there are many variations of ABS. A four channel, four sensor ABS is the best because all four wheels are monitored and controlled separately. In a three channel, three sensor ABS, the back two wheels are controlled by only one sensor, while there are two censors for the front two wheels. This system is often found on pickup trucks. In a one channel, one sensor ABS, the same valve controls all four wheels. The ABS systems allows so the driver does not need to pump his or her break manually. Should one encounter a system in which ABS is necessary, the pumps and valves of the systems control this automatically. Conventional brakes are simpler than Anti-lock Breaks. When the driver presses down on the break pedal with his or her foot, the force is multiplied to stop the car. They do this though a hydraulic system. In the hydraulic system, the pressure exerted from the driver’s foot is transmitted to an incompressible fluid, which is always a type of oil. With the help of...
