Q: How do anti-lock braking systems work?
A: Anti-lock braking systems (ABS) use sensors at each wheel (or in the differential) to monitor wheel speed. These sensors can detect whether the wheels are about to lockup. All the ABS components (ABS pump, valve, computer/controller, and sensors) work in conjunction to minimize wheel lockup (skidding) by controlling the brake pressure at each individual wheel. By not locking up wheels, you maintain better control of your vehicle under hard braking conditions and when roads are slippery.
