What is the purpose of anti-lock brakes (ABS)?

The purpose of anti-lock brakes (ABS) is to prevent wheel lock-up during heavy braking. When a driver applies the brakes suddenly or with excessive force, the wheels can lock up, leading to a loss of traction and control of the vehicle. ABS is designed to modulate brake pressure, allowing the wheels to continue rotating even under hard braking conditions. This helps the driver maintain steering control and stability, which is especially critical when maneuvering in emergencies or on slippery surfaces.

By preventing wheel lock-up, ABS enhances overall safety by allowing the driver to steer while braking, reducing the risk of skidding and associated accidents. This is particularly important for larger vehicles, which can be more challenging to control under sudden braking situations.
