Although the intelligent configuration of modern cars is very rich，But when it comes to the most basic "security configuration"，Non -braking system is。In the entire brake system，Bad pads are undoubtedly the most critical parts，seabet myThe decisive role of the braking effect。The working principle of the braking system is mainly friction，Use the brake pads and brake discs (drums) and the friction between the tire and the ground，Convert the kinetic energy of the vehicle to the thermal energy after friction，stop the vehicle。During the daily car use，How should we maintain the brake pads? When do you need to replace the brake pads?。

Maintenance of brake pads needs to be paid attention to the following points:

1、Check the brake pads at 5,000 kilometers per driving，Not only must check the remaining thickness，Also check the wear state，Is the degree of wear on both sides the same，Whether the return is free。

2、Don't wait until the brake pad friction material is all grinded before replacing it，Even if you reach the extremely brake pad, you can use it，will also greatly reduce the motion effect，Affect driving safety。

3、Try to select the original brake pads when replacing it，This can make the brake pads and the brake disc better，Good brake effect，The minimum wear。

4、When replacing the brake pads, you must use a special tool to restore the location of the brake split pump，If you use other tools，It may cause the brake pads to die，Affecting the normal driving of the vehicle。

So how to check if your brake pads need to be replaced?

1. Look at the thickness

General new brake pads are about 1.5cm，With the increase of the use time, the thickness of the thickness will gradually become thinner。When the thickness of the brake pads is only about 1/3 (about 0.5cm), when the brake pads are only about 1/3 (about 0.5cm)，You need to replace the new brake pads。

2. Listen to the sound

If the sound of metal friction is accompanied by metal friction when you step on the brake，At this time, you need to consider replacing the brake pad。This abnormal noise is likely to be a warning sound for the brake pads to the extreme alarm，Of course it may also be the sound produced by the new brake pads after installation。

3, I feel with the feet

If you step on the brake pedal, you feel very difficult，or the deficiency of the brake pedal is significantly increased，Explain that the degree of wear of the brake pads is serious，You must change the brake pad at this time。
