Do you need to replace the brake pads for a new car
In fact, in life, many drivers are confused, so how long should the car's brake pads be replaced? In fact, there is no specific replacement time and mileage for the brake pads. We just need to choose when to replace the brake pads according to the actual wear degree. In fact, the wear degree of the brake pads is closely related to the driving habits of the riders. Even if the brake pads are completely the first mock examination, we let different drivers use them. Because the driving style is different, the wear degree is also different, We will find that some people wear out very quickly, and some even run more than 100000 kilometers without any problems. Therefore, there is no fixed time to replace the brake pads.
For ordinary new cars, the time when we replace the brake pads for the first time is actually in our driver's manual. Then you can look at the maintenance manual of your car when you are free. In general, the solutions to many problems we often encounter can be found in the maintenance manual
。 The general replacement time is about 60000 km. However, if you often go to the 4S store for maintenance or the auto repair shop, the replacement time may be early. In particular, the brake pads of the front wheels will directly affect our life safety. As long as the after-sales personnel of the 4S store detect any problem, they will prompt you to replace them immediately. Generally, we will also replace them, Because the price is not expensive, and it is a matter of life after all.
The materials of our common brake pads are generally divided into less metal and semi metal, as well as Nao and ceramics.
I. less metal brake pads
As we all know, metal brake pads are divided into less metal and semi metal, but their characteristics are basically the same. However, the cost of less metal brake pads is relatively low, and the friction coefficient is also very low. The general friction coefficient is 0.38, so the service life will be relatively short.
Second, semi metal brake pads
About 30% to 65% of the friction materials used for semi-metallic brake pads are made of metal, including copper and iron. However, this kind of brake pad is characterized by fast heat dissipation and good high temperature resistance, and the price will be relatively low. The disadvantage is that due to the material, the noise generated during braking will be relatively large, and we all know that the metal material also has great wear on the brake disc, and then the anti-aging performance is not very good, and the service life is not long.
