It\u2019s one of those advances in technology that affects our\neveryday life that we hardly ever think about. Before the introduction of ABS\n(anti-lock braking system), braking wasn\u2019t anywhere near as simple and\neffective as it is today. <\/p>\n\n\n\n
Prior to the \u201870s, if you had to stop suddenly, it wasn\u2019t\nsimply a matter of slamming on the brakes as hard as you could; you had to\npractice threshold braking, which involved compressing the brake pedal enough\nto slow you down but not so much that the wheels locked and sent the car into a\ndangerous, and possibly fatal, skid. Imagine the presence of mind needed.<\/p>\n\n\n\n
Or, if you found yourself on icy roads or slippery surfaces,\nyou might have had to employ another lost technique called cadence braking,\nwhich involved mimicking modern-day ABS systems by manually pumping the brakes.<\/p>\n\n\n\n
It may seem like a silly question, but it\u2019s worth\nconsidering. If your wheels lock, the brakes no longer have any ability to slow\nyou down, and you also have a very limited ability to steer the car; not only\ncan you not slow down effectively, but you can\u2019t avoid what\u2019s in front of you.\nTherefore, an ABS not only helps you brake and come to a stop a lot quicker, it\nalso allows you to steer and avoid collisions. <\/p>\n\n\n\n
At a basic level, your ABS has the ability to sense\nindividual wheel speed, and therefore determine when a wheel has stopped\nspinning. When a wheel stops spinning it means the brakes are no longer having\nany effect.<\/p>\n\n\n\n
To combat this, the ABS releases the brake pressure on that\nwheel and then rapidly reapplies it, over and over again in quick fire\nsuccession. If you\u2019ve ever noticed the brake pedal shuddering under your foot\nwhen you slam it on hard, don\u2019t be alarmed \u2013 this is the ABS functioning as\nit\u2019s meant to. <\/p>\n\n\n\n
To explain how the ABS manages to do this, we have to get a\nbit technical. Your car is equipped with something called a tone ring which\nturns in time with the wheels. It has a magnetic speed sensor which allows it\nto detect wheel speed. The information is passed on to the ABS through an\nelectronic control unit. The ABS can then adjust your wheel speed through a\ndistribution block and pump which controls individual brake calipers. <\/p>\n\n\n\n
It\u2019s rare for an ABS to malfunction on most models. If\nsomething does go wrong, however, it will most likely be a sensor contaminated\nwith debris or metal shavings. Also, wiring can become damaged and brake fluid\ncan become contaminated.<\/p>\n\n\n\n
Because the ABS is a part of the entire braking system of\nyour car, if something does go wrong with it, it can affect not only the\nanti-locking ability but the brakes in general. <\/p>\n\n\n\n
If you feel your car is taking longer to brake, or you have to compress the pedal further before you notice any effect, call us right away and book your car in for a check. You do not want to be driving around with compromised brakes. <\/strong><\/p>\n\n\n\n
