The wear of brake pads is not a small problem. When these signals appear, replace them
In the normal use process, the brake pad will rub with the brake disc, and then make the car stop. Once the brake pad fails, it will seriously affect the braking efficiency. It is the failure of the car to decelerate quickly, which leads to rear end collision, pedestrian collision and other safety accidents. Therefore, we need to ensure that our brake pads can always work normally, which requires us to replace them before they fail. But when should I replace the brake pads?
Brake pad wear
Whether they are made of metal, organic, ceramic or composite materials, they will lose a small amount of material due to wear after each braking. Finally, they will become thinner and thinner. The thinning of brake pads will cause the heat generated by friction can not be dissipated in time, and the temperature of brake pads will rise rapidly, which will reduce the braking efficiency and lead to longer braking distance. In the end, they wear out completely, which can cause a lot of serious problems.
If you find that your brakes are not as sensitive as they used to be, or that your braking efficiency declines rapidly, or that the pedal feels different after you have been driving for some time, it may be time to replace the brake pads. It is recommended that you check the brake pads every time you change the oil, because the service life of the brake pads may vary greatly under different service conditions. Your driving style and whether you often drive in hilly areas or in heavy traffic will have a huge impact on the service life of the brake pads.
warning signal
Some cars have brake pad sensors, which can inform the driver that the brake pads are seriously worn through the lights on the dashboard or the message displayed when starting. In other cars, when the brake pads are too thin, the metal plates attached to the brake pads will make a squeal. If you continue to use them, the squeal will become smaller and there will be more grinding noise. This means that the friction pads on one or more wheels may have completely disappeared, and further use will seriously damage the brake disc. Once you hear this kind of sound, you must take the vehicle to the repair shop immediately. Ideally, you should replace the brake pads before you notice this warning.
Timely replacement
In order to ensure that your car can stop consistently, quickly and safely, I strongly recommend that you replace the brake pads before the occurrence of the above or more serious abnormalities. Worst of all, you need to replace the brake pads in time after the emergence of the appeal warning signal, rather than after weeks or even months.
From a safety point of view, brake pads are more important than engines. After all, engine failure will only make you unable to use the car, and poorly maintained brake pads will not stop when you need to stop, which may endanger the lives of drivers and passengers. So in order to use the car safely, remember to replace your brake pads in time.
