The wear of automobile brake pads is very important to driving safety. Although vehicles are usually equipped with brake wear indicators to remind the driver to replace the brake pads, sometimes we need to judge the wear of the brake pads by not disassembling the vehicle.

First of all, we can use hearing to judge the wear of the brake pads. When the brake pads are worn to a certain extent, a sharp friction sound will be produced. Therefore, when you brake, if you hear an abnormal harsh sound, it is likely that the brake pads have worn to the limit and need to be replaced immediately.

Secondly, we can judge the wear by observing the brake pads of the vehicle. It should be noted that when observing, we must make sure that the vehicle has stopped and the brake pads no longer have friction. Using a flashlight or similar tool, we can observe the wear of the brake pads through the spokes of the wheel or the gap between the brake pads. If the thickness of the brake pad is close to the limit, then we can see the metal gasket on the brake pad, which means that the brake pad needs to be replaced.

In addition, we can also judge the wear by observing the color of the brake pads. Under normal circumstances, the new brake pads are lighter in color, and the severely worn brake pads are darker in color. Therefore, by comparing the color difference of the brake pads on both sides of the vehicle, we can preliminarily judge the wear of the brake pads.

In short, through hearing, observing and comparing the brake pads, we can initially judge the wear of the brake pads without dismantling the car. However, these methods only provide a rough judgment. In order to ensure driving safety, it is recommended to check the brake pads regularly and replace them in time according to the manufacturer's recommendations.
