With Labor Day bringing about the unofficial end of summer, it's worth thinking about your vehicle's performance in wetter weather and even ice. A key component for keeping you safe in slippery conditions is your Anti-Lock Braking System, or ABS for short. If yours hasn't been checked in a while or worse, your ABS light has been on for months, beat the pre-winter crowd and visit Borgman Service today!

As anyone who drove during the 70s will tell you, ABS was a miraculous invention. Instead of "pumping the brakes" during a skid, you simply hold the pedal down and a complex system of pressurized fluid does the rest. When it was first introduced, the goal was to mimic what a skilled driver would do when the wheels lock up under heavy braking. Now, the system performs all sorts of functions, including altering the front/rear brake bias, improving handling, improving vehicle stability, traction control, electronic brake-force distribution, and even emergency brake assist.

In this article, we'll briefly describe how this system works, how often it needs service, and what to look out for if the system starts to fail.

How Anti-Lock Braking Systems Work

As Anti-Lock Braking Systems became more widespread and sophisticated, automakers found that they outperform even professional drivers. In brief, here's the problem that ABS solves:

If the road is slippery and/or the wheel overcomes the friction of the road and starts spinning freely, you not only lose the ability to easily stop but your steering is impacted as well. In its most basic form, ABS course-corrects for both of these issues.

Here's how it works. Within the ABS system, there are four main components: speed sensors, a pump, a controller, and a series of valves. As a wheel starts to "lock up," the speed sensors send a signal to the controller. This is the computer that orchestrates the ABS process. Then, the valves spring into action, allowing or restricting the flow of brake fluid to the four calipers. If pressure is let off but is again needed, the pump will pressurize the fluid. The computer will take in the variables from the speed sensors and use the valves and pump to return the four signals to the same value, meaning that the wheels are all spinning at the same speed.

When the ABS is on, you'll feel a pulsing through the brake pedal. This comes from the valve's opening and closing action and just means that the ABS is doing its job. This is why it's important NOT to pump the brakes in slippery conditions, as the controller has to start over every time you release the pedal.

What Happens If The ABS System Starts To Fail?

If you notice screeching or grinding when you bring the vehicle to a stop, or you notice reduced brake performance or "shaking" when you slow down, your brake pads and rotors are likely the culprits. You'll still need to make an appointment at the Borgman Service Center, but your ABS system likely will not need service.

If your ABS light comes on, this usually means that the controller has detected a faulty speed sensor, a fault within one of the valves, the pump, or a software issue within the controller itself. If it is blinking, that means that the system isn't functioning and needs service immediately. Hopefully, this is what alerts you to an issue, because the main symptom would be the wheels locking under heavy braking. This comes with limited steering and can be a dangerous situation if you're not expecting the fault.

If you don't have leaks in your brake fluid lines, an ABS light usually comes on if you have a faulty speed sensor, which is not a difficult repair. Even if you have no problems, we recommend having the system looked over periodically to make sure there are no slow leaks or fraying wiring. Our certified technicians will also be able to detect any anomalies by looking at your vehicle's onboard diagnostics.
