What does the brake pad warning mean?

Brake pad warning usually indicates that the wear of the front brake pads has approached the limit, reminding the owner to replace the brake pads. When the wear indicator line of the brake pads is worn through, it triggers the brake pad warning, at which point there is usually a small amount of thickness left on the brake pads. Below is relevant information: Replacement of car brake pads: There is no fixed interval for replacing brake pads; it 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 brakes less often will naturally experience less wear on their brake pads. Car fault indicator lights: Car fault indicator lights are divided into fault warning lights and reminder indicator lights. Fault warning lights are red, indicating a serious fault or an important warning that must be addressed immediately or promptly. If the light is yellow, it serves as a reminder to the owner. Although not as severe or urgent as the red light, it still indicates a corresponding issue that should not be ignored.
I remember last month when I was driving to the suburbs for a trip, the brake pad warning light suddenly appeared on the dashboard. It’s usually a small icon with an exclamation mark or a brake pad symbol, indicating that my brake pads were worn out and needed replacement. When it lit up, I felt a pang of worry because brake failure can be extremely dangerous, especially at high speeds or downhill, where losing control is more likely. Most cars have sensors near the brake discs that monitor the pad thickness—once it falls below the safety limit, this warning is triggered. Don’t ignore it! Delaying can lead to longer braking distances or even complete failure, drastically increasing the risk of accidents. I immediately went to a repair shop, and sure enough, the pads were worn down to the metal. The mechanic said I was lucky to come in early—otherwise, I’d have had to replace the brake discs too, costing hundreds more. My advice: if you see this warning, don’t hesitate—head straight to a professional shop for a check-up to ensure safety in one go.
I often do some minor maintenance on my car myself. The other day when I saw the brake pad warning light come on, I knew the brake pads were worn down again. This warning system is actually quite smart—it uses sensors installed on the brake calipers to monitor the pad thickness in real time. When the thickness drops to a critical point, it flashes the light to remind you to replace them. I usually check it myself first by removing the tire to see if the pads are thin. If the caliper measurement shows less than 3mm, it's time to take action. But honestly, since this involves safety, it's better left to professional technicians. They can perform a comprehensive diagnosis to avoid mistakes that could lead to bigger issues. After all, replacing new pads also requires adjusting the entire brake system. If this light suddenly appears while driving, it means you should pay attention. Regular maintenance can prevent premature pad replacement, saving money and giving peace of mind.
