How to Check Your Car's Brake Pads?

Methods to check your car's brake pads: 1. Check the thickness of the brake pads. When visual inspection shows that the thickness of the brake pads is only one-third of the original thickness, the owner should increase the frequency of self-inspection and be ready to replace the brake pads at any time; 2. If there is a metallic scraping sound like "iron rubbing against iron" when lightly applying the brakes, the brake pads must be replaced immediately, as the limit indicators on both sides of the brake pads are already directly rubbing against the brake disc, indicating that the brake pads have exceeded their limit. Car brake pads, also known as car brake linings, refer to the friction material fixed on the brake drum or brake disc that rotates with the wheel. The friction lining and friction block bear external pressure to generate friction, thereby achieving the purpose of vehicle deceleration.
I think checking brake pads is actually quite simple and can be done by yourself. First, park the car on a level surface and engage the handbrake for safety. Then use a jack to lift the wheel, and after removing the wheel, you can see the brake caliper. Through the small window on the caliper, you can directly observe the thickness of the brake pads—new ones are usually 10 to 12 mm thick, and if only about 3 mm remains, it's time to replace them. I also often listen to the sound when braking; if there's a squealing or metal grinding noise, that's the wear indicator reminding you to replace them. Regular checks every 5,000 kilometers can save a lot of worry and prevent accidents caused by brake failure. Additionally, remember to check the brake discs for obvious scratches or abnormal wear while inspecting, which can help you address issues before they worsen. In short, once you get into the habit, it takes less than half an hour to complete.
As a car owner who frequently maintains my own vehicle, I emphasize safety first—brake pads are a matter of life and death. When inspecting, first remove the wheels and measure the thickness directly: if it's less than 3 millimeters, it's time to replace them. Also, pay attention to the condition of the brake discs; grooves or deformations can affect braking performance. During regular driving, be alert to unusual noises—a sharp squealing sound indicates severe wear. It's reasonable to check them quarterly, especially before long trips; if you notice rapid wear, replacing them early can save on repair costs and ensure your family's travel safety. Remember to wear gloves during the operation to avoid dirty hands or injuries.
