How many kilometers does a car brake pad need to be replaced? How to check it yourself

In the car maintenance project, the maintenance of the brake item is the most important thing, but many consumers have a wrong understanding of the brake maintenance, or it is because the old driver made a wrong judgment in a word, more typical such as brake pads Replacement cycle! Some car owners reported that the brakes were changed for more than 30,000 kilometers, while other car owners reported that they continued to run for 60,000 kilometers...Which old driver is right? Today we will talk about the maintenance cycle of brake pads.

For the replacement cycle of brake pads, car owners also follow the recommendations of repair shops and 4s shops. In general, repair shops and 4s shops will give the correct choice. Of course, some black-hearted businesses are not ruled out. They judge the brakes of the vehicle only by the mileage of the car. Should the film be replaced! In fact, in most cases, it is hardly reliable to judge the replacement cycle of brake pads by mileage.

The correct inspection method is also very simple, a flashlight + visual inspection can be completed, when the rear brake pad is worn to the visual inspection and needs to be replaced. Many car owners will say that there is a wear alarm on the brake pads, as long as the alarm is worn off and replaced, it is ok! This method is a more worry-free method, but the alarm sensor of most models is one-sided. If there is partial wear of the brake pads, it is difficult for the owner to make a judgment! In short, this method is very practical for novice drivers!

Going back to the car owner's question mentioned at the beginning, some brake pads need to be replaced for more than 30,000 kilometers, and some need more than 60,000 to replace! Is there anything weird in this? The main reason for the different mileage of brake pad replacement is that their braking performance is different, and the degree of hardness of the brake pads is different. How do you understand it? For example, when buying a new car, everyone pays attention to the braking distance and wants to shorten the braking distance. In addition to tires, vehicle weight, and ABS, a very important reason is the brake pads. Generally speaking, the softer the brake pads, the better the braking performance. , The shorter the braking distance can be done, and vice versa! For ordinary family cars, the brake pads are ok as long as they meet the general performance, so the brake pad material is more wear-resistant and harder!

f you want to learn more about brake pads, you can start with its composition. The brake pad is composed of a friction material layer, a heat insulation layer, an adhesive layer, and a back plate. Its working principle is to press the friction material of the brake pads on the brake disc to brake through the brake cylinder to push the back plate, so the brake pads are very important for braking!

Finally, it should be noted that the driver’s driving habits also have a great impact on the life of the brake pads. If the driver likes to drive fast and brake heavily, the life of the brake pads will often be particularly short. Road conditions are also important, such as driving road conditions. The city is congested and the stop-and-go brake pads are also worn out! In a word, driving habits, road conditions, and brake pad materials all affect its replacement cycle, so if you want to avoid wasting money, you must learn to "check the brake pads yourself"!
