How often do the brake pads change? That's the right way
Many friends like to pursue speed when driving, but at the same time, they should also pay attention to safety. As one of the most important parts of a car, brake pads are not so huge in volume, but they play an important role. Today, Xiao Bian will take you to talk about how to check the brake pads correctly and replace them in time
There is no specific replacement date for brake pads. They are consumables and need to be inspected to determine whether they need to be replaced.
1. Location of brake pads
The brake pad is located on the inner side of the four wheel hubs. There are two internal and external brake pads. From the outside, you can see the external brake pad with the naked eye.
2. Judge the condition of brake pad
Generally, to accurately judge the condition of the brake pad, it is necessary to remove the tire, in order to particularly clearly check the wear situation, so Xiaobian here suggests that you do not easily try.
If the thickness of the brake pad is less than 3mm, the brake pad needs to be replaced. If the thickness is about 1cm, the brake pad does not need to be replaced.
If you have no way to remove the tire by yourself, you can check the dashboard to see if there is something wrong with the car. In cars with higher configuration, the dashboard is equipped with a brake indicator. If there is something wrong with the brake pads, it will light up to warn you that you need to replace the brake pads quickly. Of course, if you don't have a special indicator, don't worry. You can speculate from other indicators.
In addition, many brake pads have an alarm pad, which is used to remind the car owner that when the wear degree of the brake pad reaches the limit value, the small brake pad will rub with the brake disc and make a sharp noise. At this time, it is urgent to check and replace the brake pad.
3. Wear position of brake pad
In many cars, the brake pads of the front wheels are worn faster and the rear wheels are worn more slowly. Therefore, the speed of replacement is probably that the front wheels are replaced twice and the rear wheels only need to be replaced once. Of course, the specific situation depends on the individual use method.
4、 Types of brake pads
According to the composition and price, asbestos brake pads are the worst and the cheapest, followed by semi-metal brake pads, less metal brake pads and the most expensive ones are Nao ceramic brake pads. Because of the poor performance of asbestos brake pads, they can not meet the standard, so they have been eliminated now. Most cars use Semi-metallic Brake Pads when they leave the factory. This kind of brake pad is the cheapest compared with others, so its friction coefficient is also lower.
5、 Mistakes after replacing brake pads
Some friends will find that there is still abnormal noise after replacing the brake pads. What's the matter? Don't be nervous. This is a normal phenomenon. After replacement, the brake pads need to be run in with the car. Therefore, there will be abnormal noise after the friction of the brake disc, but it will return to normal after a period of running in.
