What does the brake pad warning mean?

Brake pad warning usually indicates that the front brake pads are nearing their wear limit, reminding the owner to replace them. When the wear indicator line on the brake pad is worn through, it triggers the brake pad warning. At this point, there is usually a small amount of thickness left on the brake pads, and it is generally safe to drive another 300 to 500 kilometers. However, the brake pads should be replaced as soon as possible to avoid damaging the brake discs. There is no fixed replacement interval for brake pads; the need for replacement should be determined based on actual wear. Most people replace their brake pads every 30,000 to 80,000 kilometers. Those who frequently drive on highways or use their brakes less often will naturally experience less wear on their brake pads, resulting in fewer replacements.
Last time I was driving on the highway, a small red warning light suddenly appeared on the dashboard, showing a brake pad symbol. I thought the car was about to break down and got so scared that my palms were sweating. Later, after asking a friend, I learned that this was the brake pad wear indicator, meaning the brake pads had worn too thin and were approaching the safety limit – the system was warning me to replace them. This is actually an intelligent design feature in modern cars: there's a small sensor that triggers the warning when the pad thickness decreases to a certain level, reminding you to address it promptly before brake failure occurs. I immediately drove to a repair shop for inspection, and the mechanic said the pads were just a few millimeters away from being completely worn out. After replacing them, everything was fine. Now I understand that this warning light must never be ignored as it relates directly to driving safety – especially during rainy conditions or emergency braking when poor braking performance could be fatal. I recommend that new drivers like me should stay calm when seeing such warnings: first slow down and pull over, then promptly visit a professional service center. Don't try to save a few bucks at the risk of safety.
