1. Look at the thickness of the brake pad
When the thickness of the brake pad becomes very thin, the braking performance will be greatly reduced, which will affect the safety of driving. Generally, the thickness of the new brake pads is about 1.5cm. When the brake pads are worn to only 0.5cm, you need to increase the frequency of the self-test. When the brake pads are worn to only 0.3cm, you must replace them in time. This is the limit for the thinner brake discs. Don't drag and drop the car in minutes.
2. Driving computer prompts to replace
Generally, there are brake warning lights on the dashboard of the car. When the warning light is on, it reminds you to check the brake pads. However, the warning light indicates that the limit has been changed, and it must be checked immediately. All cars have this kind of warning system, but some directly sense the thickness of the brake pads, while others have the brake pads completely finished, and the brake fluid is extremely lowered to make the warning lights light up.
3. Listen to the sound
The brake discs are mostly iron. After parking for a long time, especially in the rainy days, it is easy to appear rust. At this time, the brakes will be accompanied by the sound of the silk. This sound will disappear after driving for a while. If it does not improve after a period of time, the brake pads must be replaced immediately. Because the limit marks on both sides of the brake pads have directly rubbed the brake discs, it proves that the brake pads have exceeded the limit. In addition, in this case, when the brake pads are replaced, the brake discs should be checked. When such a sound occurs, the brake discs are already damaged. At this time, even if a new brake pad is replaced, the sound cannot be eliminated. In severe cases, the brakes need to be replaced. plate.
