Watch: How Do Hub Bearings Affect Braking Safety?

Hub bearings include the wheel speed sensor that controls the anti-lock braking system (ABS). This sensor sends a constant signal to the ABS control system, telling it how fast each wheel is turning.

So how do hub bearings affect braking safety? Hub bearings include the wheel speed sensor that controls the anti-lock braking system (ABS). This sensor sends a constant signal to the ABS control system, telling it how fast each wheel is turning. In an emergency situation, the ABS control system will determine if anti-lock braking is required.

If the ABS sensor doesn’t work properly or fails, the ABS system fails, so the quality of this sensor — how it is made and protected from damage — is critical to braking safety. And a word about traction control. You might wonder why hub bearings are critical to traction control systems? A vehicle’s traction control system uses a combination of electronic drivetrain controls in conjunction with the ABS system. Since it uses the same wheel speed sensors and components as the ABS system, it can be considered a subsystem and extension of that system. Together, anti-lock braking and the traction control system work to provide the driver with full control over the vehicle.
