How long can the brake pads be used?
The life of brake pads is difficult to define with a clear number of kilometers or time.
Because the materials of the brake pads are different, everyone has different driving habits, driving conditions are different, and the frequency of using the brakes is different, so the wear of the brake pads will be different. Some people need to replace brake pads after 20,000 to 30,000 kilometers, and some people may not need to replace brake pads for 100,000 kilometers.
In fact, stepping less on the brakes is one of the core principles of fuel-efficient driving. In addition, the wear degree of the front and rear brake pads of the same car may also be different (generally, the front brake wears faster), and there will be subtle differences between automatic transmission and manual transmission (automatic When blocking traffic jams, the brakes are often loosened), in short, it is impossible to generalize.
How to judge whether the brake pads need to be replaced?
1. look
The easiest way is to look at the prompts on the dashboard. When the brake pad indicator light is always on, it is necessary to replace the brake pads in time.
Of course, we can also observe the thickness of the brake pads more often to know what we know.
Usually, the thickness of a new pair of brake pads is about 1.5cm.
If your brake pads are less than 5mm thick, consider replacing them.
Due to the angle of viewing, etc., there will still be errors, and the inner brake pads are sometimes difficult to see, so it is best to ask the master to help you look at each maintenance.
Of course, the wheels of some cars are special, and the brake pads may not be visible, so you need to remove the tires or go to a repair shop for inspection.
2. Phenomena that need attention
Measurement and inspection is the safest way, but there are some phenomena that can also prompt us to the degree of wear of the brake pads. When you hear the sound of creaking metal friction when braking, there may be a problem with the brake pads, so be sure to check it as soon as possible.
3. Is it reliable by feeling?
It is unreliable to judge whether the brake pads need to be replaced by the feeling of stepping on the brakes. When the brakes are soft or the braking force is insufficient, there may be problems with the brake pipeline, etc. There are many reasons involved. So it's best to use it to see, seeing is believing.
