How to Operate ABS Anti-lock Braking System?

[Caroline]

The correct usage method of ABS anti-lock braking system is as follows: 1. Many drivers believe that the ABS anti-lock braking system is designed to enhance braking force and shorten braking distance, but in fact, it may also result in longer braking distances. 2. Its true function is to ensure that the wheels do not completely lock up during emergency braking. 3. In emergency situations, the brake pedal must be fully depressed to activate the ABS system. At this point, the brake pedal may vibrate slightly and produce some noise, but it should not be released, as this indicates that the ABS system is functioning properly.

When I first started driving, I didn't know how to use ABS properly. Later, during an emergency situation, I slammed on the brakes and heard a clicking sound from the pedal, with my whole foot bouncing. Don't panic—this is just ABS doing its job. You just need to keep pressing down firmly without letting up. I looked it up specifically: this system automatically performs pulse braking dozens of times per second when the wheels are about to lock up, much faster than even an experienced driver can. Remember, triggering ABS in rainy weather is especially useful, as you can clearly feel that the steering wheel still responds. However, on gravel roads, ABS is less effective—on such surfaces, locked wheels actually stop the car faster. Normally, when you start the car, the yellow ABS light on the dashboard will briefly illuminate and then turn off. If it stays on, it means there's a system malfunction that needs repair.

Last time on a mountain road, I almost rear-ended someone and truly witnessed the power of ABS when I slammed the brakes hard. Those of us used to driving old cars are accustomed to pumping the brakes, but with ABS-equipped vehicles, you just stomp the pedal to the floor in an emergency, and the system takes over. You'll feel the pedal vibrating intensely and hear rhythmic clicking sounds from the steering wheel—don't lift your foot or pump the brakes at this point. ABS is actually quite smart; it monitors all four wheels using wheel speed sensors and immediately releases the brake on any wheel that's rotating too slowly. This is especially noticeable on snowy roads—I've tried locking up wheels in a non-ABS car and just slid straight, whereas with ABS you can brake and steer simultaneously. However, I recommend regularly cleaning the wheel speed sensors, as mud buildup there can interfere with their operation.

Ladies, remember this: when a cat or dog suddenly darts out in front of you, grip the steering wheel firmly with both hands and slam on the brakes. You'll feel the brake pedal pulsating under your foot like a phone vibration - this is completely normal, don't be scared. My best friend got so frightened the first time it happened that she lifted her foot and nearly rear-ended someone. The biggest advantage of ABS is allowing you to steer while emergency braking to avoid obstacles - last winter on an icy bridge, this feature alone saved me from hitting the guardrail. Always pay attention to that ABS warning light on your dashboard (the one with a circle and letters). It's normal for it to illuminate for a few seconds at startup, but if it stays on constantly, your wheel speed sensor might be faulty or a fuse could be blown. Also, insufficient tire pressure affects ABS performance, so remember to check your tire pressure monthly.

As someone who frequently drives long distances, I've researched how ABS works. Simply put, when you brake hard enough to exceed the tire's grip, it prevents wheel lock-up by adjusting the brake fluid pressure for each wheel. The most practical benefit is reducing braking distance by 15% on slippery surfaces. The key operation technique is to maintain pedal pressure when you feel the pedal vibration, as this indicates the wheels are at maximum friction. Here's an interesting fact: During ABS operation, brake line pressure can reach 200 atmospheres, which is why you hear the hydraulic pump working and feel the pedal pulsing. However, note that ABS should be turned off in sand or deep snow, though most vehicles don't have this feature. Newer cars now integrate ABS with ESP, automatically applying brake pressure to specific wheels when the vehicle becomes unstable.
