Brake pads are very important components in the automotive braking system, and its degree of wear directly affects the braking performance and safety of the car. So, to what extent do brake pads wear out and need to be replaced? This article will give you a detailed answer.
First of all, it is necessary to understand the main role of brake pads. Brake pads are friction materials in the braking system, which generate braking force through friction with brake discs or brake drums to slow down or stop the vehicle. Therefore, the degree of wear of brake pads is directly related to the braking performance of the car.
In general, the degree of wear of brake pads will be affected by a variety of factors, such as mileage, driving Xi, road conditions, etc. Depending on the driving conditions and Xi, the degree of wear of the brake pads will also vary. However, typically, brake pads have a lifespan of between 30,000 and 80,000 kilometers.
So, how can you tell if a brake pad needs to be replaced? First of all, it can be judged by looking at the thickness of the brake pads. Normally, the new brake pad thickness is in 15 cm or so, when the brake pads wear down to only 0When it is about 5 cm, it needs to be replaced. In addition, it can also be judged by listening to the sound. When you hear a sharp metal grinding sound when braking, it is likely that the brake pads have worn out to the limit and need to be replaced with new ones.
What are the problems caused by not replacing worn brake pads in time? First of all, the braking performance will decrease, resulting in an increase in the braking distance of the vehicle, and the braking time will be extended, increasing the risk of traffic accidents. Secondly, the brake discs are subject to wear and tear, and when the brake pads are worn to the limit, the brake discs are also worn, causing the braking effect of the vehicle to be affected. Finally, if the brake pads are not replaced for a long time, it may lead to brake failure, which poses a threat to the driver's life.
To sum up, it is very important that the brake pads are worn to a certain extent and need to be replaced. Generally speaking, when the thickness of the brake pads is reduced to 0When it is about 5 cm, it is necessary to replace the brake pads with new ones. If worn brake pads are not replaced in time, it will lead to problems such as reduced braking performance, brake disc wear and life safety threats. Therefore, it is recommended that drivers regularly check the wear of the brake pads and replace them with new brake pads in time to ensure the braking performance and safety of the vehicle.
