Modern brake systems are safer and more effective than ever. The flaws of older brakes are being fixed by technological advances so that driving safely is easier, no matter the road conditions—that’s where your anti-lock brake system comes into play. At the same time, it’s as important as ever to keep up with proper maintenance so that your brakes are always in good operating condition. Let’s dive into what your anti-lock brake system (ABS) does, how it differs from conventional brakes, and how to keep your brakes well-maintained and healthy.
What Does Your Anti-Lock Brake System Do and How?
In most situations, you’re able to see in advance that you need to slow down and can brake gradually. However, imagine you’re driving in traffic and the car in front of you suddenly brakes hard—you have to follow suit and slam on your brakes. If roads are slick or wet, it can be even more difficult to safely stop in time—cue your anti-lock brakes. The anti-lock brake system (ABS) is built into most modern vehicles as a safety feature to help prevent any of your wheels from locking, which makes it even more difficult to maintain the traction necessary to slow your car.
How Does Your Car’s ABS Work?
If you’ve been driving for a long time, you may have noticed that advice has changed—in the past, it was recommended to pump the brakes in emergencies, but now it’s the opposite. That’s because your car’s ABS facilitates pumping the brakes for you so that you can focus solely on steering to safety. Wheel speed sensors monitor the rotation of each of your car’s wheels. If one locks up, a controller automatically pumps the brakes up to 20 times per second. This allows you to maintain control of your vehicle as much as possible, even in emergency situations with low traction.
Conventional Brakes vs Anti-Lock Brakes: What’s the Difference?
Ultimately, conventional brakes and the anti-lock brake system work hand-in-hand. Under normal circumstances, your regular brake system with pads and rotors is all you need to come to a safe, easy stop. However, in low-traction situations, your ABS is ready to kick in and help you maintain control of your vehicle by assisting the conventional brake system.
ABS Brakes are No Replacement for the Right Driving Habits
Though an anti-lock brake system is a helpful safety feature in most vehicles, it’s no replacement for the right driving habits and knowing what to do in adverse driving conditions. Always look ahead on the road so you can catch changes in traffic, red lights, and other obstacles as soon as possible, minimizing the risk of emergency braking. Avoid following too closely behind the car ahead of you. Anticipate stops as early as possible so that you can brake gently rather than using more force at the last minute. These habits will all help you stay safe and keep your brake components healthy longer.
How to Maintain Your Car’s Anti-Lock Brake System
Both your regular brakes and anti-lock brakes benefit from routine maintenance. This includes regular inspection and replacement of key components, including the brake fluid and sensors, as well as paying attention to changes in performance or warning lights on your dashboard.
Routine Brake Fluid Services
As a hydraulic system, brake fluid is central to your ability to slow your vehicle. Though it doesn’t typically need much maintenance, it is important to follow the schedule in your owner’s manual for inspection and replacement of the brake fluid. Typically, it’s recommended to do this about every 2-3 years or 30,000-45,000 miles. Not only will it help the overall performance of your car’s brakes, but it can help prevent the buildup of moisture in the system, which can lead to rust and corrosion.
Inspection of Wheel Speed Sensors
Without well-functioning wheel speed sensors, your car’s ABS can’t properly do its job. These sensors monitor the rotation of each wheel so that if one locks and stops spinning, ABS can kick in and pump the brakes to that wheel, helping it regain traction. By keeping these sensors free of dirt and grime or having them replaced, you’ll help ensure you can safely stop, even in low-traction conditions.
Watch for the ABS Warning Light
Your car has built-in warning lights that will illuminate on your dashboard, alerting you to various issues—one to watch for is the ABS warning light. If this comes on, there may be a serious problem with your car’s anti-lock brake system that could put you at risk in adverse driving conditions. Have a mechanic inspect your car’s brake system, including the ABS, and handle any necessary repairs.
Pay Attention to Signs of Trouble with Your Car’s ABS
Aside from the ABS warning light, you may notice other signs of trouble. Does your brake pedal feel spongy or unresponsive? Are there unusual pulsations during braking? Do your brakes lock up, especially in emergency situations? These can all point to an issue with your anti-lock brake system that need to be fixed by a professional brake mechanic.
