Driving safety has always been the owners of the more important. In addition to driving at ordinary times to pay more attention to safety, regular maintenance of the vehicle is also very important. But different people road sense and road conditions are different. The maintenance manual is not completely accurate. So we can not blindly in accordance with the maintenance manual for vehicle maintenance. To combine the actual situation to replace parts, in order to ensure driving safety. Brake pads belong to a kind of consumables in auto parts. It is also the most critical safety part of the car. All the brake effect is good or bad by the brake pad plays a decisive role. It is often heard that the maintenance master said that the brake pads should be replaced at a time of 50,000 kilometers. But car maintenance manuals advise owners to replace brake pads every 30, 000 kilometers. Is it 30,000 kilometers or 50,000 kilometers for replacement? In fact, there is no fixed replacement frequency of brake pads. Drivers will need to replace the brake pads of the vehicle. As long as the driver in the road when driving the following several situations.
The abnormal sound of metal friction occurs during the braking process. As the brake material structure is mostly iron. So the car is not placed for a long time, or in rainy weather, brake pads are easy to rust aging. This time to step on the brake will be accompanied by similar metal friction harsh sound. If the harsh sound still exists after a period of time, it means that the brake pads have exceeded the limit of use. The limit mark of the brake has been rubbed directly against the brake disc. The brake pads must be replaced at once.
Check the thickness of brake pads for wear. The thickness of the general new brake pad is about 1.5 cm. Brake pad thickness gradually thinning, will cause a significant decline in braking performance. When the thickness of the brake pad is only 0.5 cm, the owner needs to check the brake pad frequently. Generally, there will be a limit wear mark at 3 mm of the brake pad. When the thickness of the brake pads is worn to the same thickness as this sign, it means that the brake pads need to be replaced. This is the limit of the thickness of the brake pads, if not replaced, the car may brake failure at any time.
Braking distance is longer than before. The owner should check to see if the brake pads need to be replaced. When the driver stepped on the brake to be able to achieve the braking effect before. When stepping on the brake, the brake becomes soft. When the brake distance becomes longer than before. And there is a point when the brake does not live.
If the owner is a novice or often drive in the city, then brake pad wear will be higher. So the owners should check and replace the brake pads in time. In order to avoid unnecessary security risks.
