THE SCIENCE BEHIND ANTI-LOCK BRAKES

Bryna Christensen • March 24, 2025

WHY THEY KEEP YOU SAFE

At Eureka Brake & Automotive, we understand how crucial it is to stay safe on the road. One of the most important innovations in automotive safety is the Anti-lock Braking System (ABS). Whether you're cruising the highways or navigating city streets, ABS plays a key role in preventing accidents by helping you maintain control of your vehicle. But how exactly does this system work? Let’s break down the science behind it.

WHAT IS ABS?

Anti-lock brakes are a safety feature designed to prevent your wheels from locking up during heavy braking. In emergency situations, or when road conditions are slick or uneven, locking the wheels can cause your vehicle to skid, reducing your ability to steer. ABS solves this by modulating brake pressure to each wheel, allowing you to brake without losing control.

HOW DOES ABS WORK?

Here’s where science comes in! ABS is all about controlling friction and maximizing traction:

1. SENSORS MONITOR WHEEL SPEED- ABS uses speed sensors placed at each wheel to monitor how fast they’re turning. If one or more wheels suddenly slow down and start to lock up, the system detects this loss of traction instantly.

2. THE CONTROL MODULE TAKES ACTION-The ABS control module, often considered the brain of the system, processes the data from the wheel sensors. When it detects potential wheel lockup, it sends signals to the hydraulic valves in the braking system.

3. MODULATING BRAKE PRESSURE- Instead of applying full braking force, ABS rapidly pumps the brakes for you—often as fast as 15 times per second! This prevents the wheels from fully locking, allowing them to keep turning while slowing down. This controlled braking action gives you better steering control in critical moments.

4. WHY IT MATTERS: MAINTAINING CONTROL- Without ABS, hitting the brakes hard—especially in a panic stop—can lead to skidding or spinning out, particularly on slippery surfaces like wet roads or ice. ABS, by continuously adjusting the brake pressure, allows you to maintain steering control and avoid hazards. It’s not about stopping faster but about stopping safely while staying in control. 

THE PHYSICS BEHIND ABS: FRICTION AND TRACTION

The magic of ABS lies in its ability to manipulate friction and traction. When your wheels lock up during braking, the tires slide along the road, reducing the **frictional force** between the tires and the pavement. This sliding friction is less effective than the **rolling friction** that occurs when the wheels continue to turn. ABS keeps your wheels turning, ensuring they maintain maximum traction with the road surface. The result? Better control, shorter stopping distances, and a reduced risk of accidents.

THE HISTORY OF ABS
While ABS is now standard in most vehicles, its origins trace back to the aviation industry. Engineers developed early versions of the system to prevent aircraft wheels from locking up during landing. In the 1970s, car manufacturers began adapting the technology for passenger vehicles, and by the 1980s, ABS became a game changer for automotive safety.

HOW TO KNOW IF YOUR ABS IS WORKING

When you start your vehicle, the ABS light on your dashboard should briefly light up and then turn off. This signals that the system is functioning correctly. If the light stays on, it’s a sign that there’s an issue with your ABS, and you should bring your vehicle in for a checkup. At Eureka Brake & Automotive, our team of professionals is equipped to diagnose and repair any ABS issues to ensure your safety.

Father’s Day is the perfect time to celebrate the practical advice and life lessons our dads have passed down over the years. At Eureka Brake & Automotive, we know that some of the best fatherly wisdom revolves around taking care of vehicles. This year, let’s focus on a simple yet essential skill: how to properly add air to your tires. Whether you’re a seasoned driver or just learning the ropes, here’s a step-by-step guide to keep your tires in top shape—just like Dad would want. WHY TIRE PRESSURE MATTERS Maintaining the correct tire pressure isn’t just about getting the best gas mileage—it’s also about safety and extending the life of your tires. Underinflated or overinflated tires can lead to uneven wear, decreased fuel efficiency, and even blowouts. Keeping your tires properly inflated helps ensure a smoother, safer ride for you and your passengers. HOW TO CHECK AND ADD AIR TO YOUR TIRES Here’s a step-by-step guide you can follow, inspired by good old-fashioned fatherly advice: 1. FIND THE RECOMMENDED TIRE PRESSURE Check your vehicle’s owner’s manual or the sticker inside the driver’s side doorframe for the manufacturer’s recommended tire pressure (measured in PSI). Don’t rely on the number on the tire itself—that’s the maximum pressure, not the recommended pressure for your vehicle. 2. GRAB A TIRE PRESSURE GAUGE A trusty tire pressure gauge is a must-have tool. Digital or analog, choose one you’re comfortable using. Many gas stations also have built-in gauges on their air pumps, but having your own ensures accuracy. 3. CHECK THE PRESSURE Remove the valve cap from your tire. Press the gauge onto the valve stem firmly until you hear a brief hiss. This means it’s sealed and ready to measure. Read the pressure on the gauge and compare it to the recommended PSI. 4. ADD AIR IF NEEDED If the pressure is too low, head to an air pump (most gas stations have them, and some are even free). Attach the pump nozzle to the valve stem. You’ll hear air flowing into the tire. Add air in short bursts and recheck the pressure with your gauge until you reach the recommended PSI. 5. DON’T OVERFILL If you accidentally over inflate, use the small pin inside the valve stem to release air gradually. Most gauges have a small nub designed for this purpose. 6. REPLACE THE VALVE CAP Once the pressure is correct, screw the valve cap back on to protect the valve stem from dirt and debris. * BONUS TIP FROM DAD: CHECK THE SPARE TIRE Dads always have a way of thinking ahead, and checking the spare tire is a classic move. Make sure your spare is properly inflated and ready to go in case of an emergency. WHEN TO CHECK YOUR TIRE PRESSURE Monthly: Tires naturally lose a small amount of air over time. Before Long Trips: Always check your tire pressure before hitting the road. When Temperatures Change : Hot and cold weather can cause tire pressure to fluctuate, so keep an eye on it during seasonal shifts. Whether it’s teaching us to check tire pressure or how to change the oil, dads (and father figures) play a big role in keeping us safe on the road. This Father’s Day, take a moment to show your appreciation by sharing these tips or passing them on to someone else. Need help with your tires? Stop by Eureka Brake & Automotive, and we’ll make sure your vehicle is road-ready. From all of us, Happy Father’s Day!

Driving is one of the most routine tasks we do, but it’s also one of the most dangerous if we’re not giving it our full attention. Distracted driving is responsible for thousands of accidents every year, and it only takes a split second of inattention for things to go wrong. At Eureka Brake & Automotive, we care about your safety. That’s why we’re breaking down the four most common driving distractions and why they’re so dangerous. 1. TEXTING OR USING YOUR PHONE This is the #1 distraction on the road, and for a good reason. Looking at your phone takes your eyes off the road, your hands off the wheel, and your mind off driving. In fact, sending or reading a text takes an average of five seconds. At 55 mph, that’s like driving the length of a football field blindfolded. Why It’s Dangerous: You lose all three forms of focus—visual, manual, and cognitive—making it nearly impossible to react to sudden changes like a car stopping or a pedestrian crossing. 2. EATING OR DRINKING It might seem harmless, but grabbing a bite while you drive divides your attention. Whether it’s unwrapping a burger or trying not to spill your coffee, you’re not fully in control of your vehicle. Why It’s Dangerous: Spills can cause you to panic and take your hands off the wheel. Plus, any time your eyes leave the road—even for a second—your risk of an accident skyrockets. 3. INTERACTING WITH PASSENGERS We’ve all been there—trying to settle a fight between kids in the backseat or chatting animatedly with a friend up front. While it’s great to have company, it can pull your focus away from the road. Why It’s Dangerous: Emotional distractions and turning your head to address passengers can lead to missed cues, like brake lights ahead or a sudden lane change by another driver. 4. DAYDREAMING OR MENTAL DISTRACTIONS Sometimes, the most dangerous distraction isn’t a physical one—it’s your own mind. Long drives or a stressful day can cause your thoughts to wander, leaving you physically behind the wheel but mentally somewhere else. Why It’s Dangerous: Mental distractions reduce your ability to make quick decisions, and in an emergency, your reaction time could be too slow to prevent a crash. HOW TO STAY FOCUSED The good news is that distracted driving is 100% preventable. Here are a few tips to keep your attention where it belongs: Put your phone on silent and out of reach. Pull over if you need to eat, text, or deal with passengers. Take regular breaks on long drives to stay alert. Keep your vehicle in top condition so it’s one less thing to worry about. At Eureka Brake & Automotive, we’re here to help with that last one. Whether it’s a brake check, an oil change, or a tire rotation, keeping your vehicle in great shape means one less distraction on the road. Let’s work together to make driving safer for everyone!
