Operation method
First of all, it can be judged by listening to the sound, because every brake pad will have a layer of iron when it is about to be replaced. When the brake pad is worn to this layer of iron, there will be a sound, which is to remind you that it is time to replace the brake pad.
Second, because the novice can't fully drive the car, he can't feel whether the brake pads should be replaced by driving on the road. At this time, you can regularly observe the thickness of the brake pads. If the thickness is obviously thin, then the brake pads should be replaced.
Third, many cars are now highly intelligent. There is a sign in the car's logo that shows whether the brake pads should be replaced. When the indicator light of the sign lights up, it will remind you that the brake pads should be replaced.
In addition, when driving, I obviously feel that the braking effect is not good, so I should quickly replace the brake pads or check the brake oil. Safety first, so I must check the brake system.
