Antilock brake systems (ABS) are an advanced braking technology designed to maximize braking efficiency so drivers have more control over a vehicle. Drivers must understand how automobiles equipped with ABS work so they can use the brakes correctly during emergency stopping situations.
Antilock brake systems use hydraulic power to pump a vehicle's brakes so the driver does not have to do so manually. The hydraulic pressure applied to the brakes with ABS is a force much greater than a driver could apply. Additionally, ABS brakes are pumped automatically at a speed faster than a human could, contributing to the system's effectiveness.
ABS has built-in sensors that detect when to apply the hydraulic pressure to the brake assembly. The sensors are located in the wheels. Each wheel contains a dedicated speed sensor that sends signals electronically to the main ABS controller to alert the system of the need to brake.
ABS is an operation that employs automatically, so drivers should not pump the brakes themselves. The proper response is to apply constant, firm pressure on the brakes when ABS is activated. Drivers who pump the brakes manually on ABS vehicles risk damaging the braking system and losing control of the automobile.
