ABS BrakesThe idea of ABS brakesAnti- locking braking system or ABS brakes are designed to prevent accidents not help you when your in an accident. The purpose of ABS, is to avoid crashes in the first place. ABS help do this by reducing the stopping distance of the car, ABS brakes will stop you faster than conventional brakes will. The name is pretty self explanatory ABS brakes stop the tyres from locking up- which is when cars begin to side on the road. By preventing the locking of the wheels you can over come the loss of traction which is quite dangerous in an accident because if you don’t have traction on the road you cannot steer your car. So with ABS brakes you can brake and turn at the same time which reduces the chances of a crash.Components of ABS brakes There are four main components to an ABS system: Speed sensors Pump Valves Controller Speed Sensors- The anti-lock braking system needs some way of knowing when a wheel is about to lock up. The speed sensors, which are located at each wheel, or in some cases in the differential, provide this information. Valves- There is a valve in the brake line of each brake controlled by the ABS. On some systems, the valve has three positions: In position one, the valve is open; pressure from the master cylinder is passed right through to the brake. In position two, the valve blocksthe line, isolating that brake from the master cylinder. This prevents the pressure from rising further should the driver push the brake pedal harder. In position three, the valve releasessome of the pressure from the brake. Pump- Since the valve is able to release pressure from the brakes, there has to be some way to put that pressure back. That is what the pump does; when a valve reduces the pressure in a line, the pump is there to get the pressure back up. Controller- The controller is a computer in the car. It watches the speed sensors and controls the valves.
