Brake pads are generally replaced in pairs, and a pair of four pieces.

If it has never been replaced, it is recommended to replace the front and rear pairs together, that is, eight pieces. If you do not know how to judge whether the brake pads need to be replaced, you can refer to the following three situations:

①The mileage of the car is 40,000 to 60,000 kilometers, and the brake pads need to be checked or replaced. The thickness of the new brake pads is about 1.5cm. When the thickness of the brake pads reaches 0.5cm, it is time to consider replacing them for driving safety.

②When stepping on the brakes, it is obvious that the brakes are weak, and the steps are soft, or the brakes must be stepped on deeply to achieve the previous braking effect, and the braking distance becomes longer, which seriously affects driving safety.

③The instrument displays the brake fault light. When the fault light is on, it means that your brake pads have reached the safety limit. At this time, when you step on the brakes, there will probably be a harsh sound when the iron rubs against the iron. In this case, it must be done as soon as possible. Go to the repair shop to check and replace new brake pads to ensure driving safety in the later period
