Is it correct that ABS shortens braking distance?

[McRyan]

Incorrect. ABS stands for Anti-lock Braking System, which prevents the wheels from locking up during emergency braking, thereby avoiding loss of steering control and potential hazards. Essentially, ABS achieves this by intermittently applying and releasing the brakes—tightening, releasing, tightening again, and releasing again. This allows the vehicle to maintain steering control during emergency braking, enabling the driver to avoid obstacles and reduce risks. Consequently, ABS tends to increase the braking distance. Here are some related details: 1. Single-channel ABS: Single-channel ABS typically controls both rear wheels based on the low-select principle. It does not fully utilize the grip of both rear wheels, so the braking distance may not be significantly reduced. 2. Wide application: Additionally, since the front wheels are not controlled, they may still lock up during braking, which does not improve steering control. However, the rear wheels will not lock up, significantly enhancing directional stability during braking—a major safety advantage. Due to its simple structure and low cost, single-channel ABS is widely used in light trucks.
