The degree of wear of brake pads can be judged based on the following aspects:
Sound: When the brake pads are worn to a certain extent, a gurgling sound will be produced when braking. This is because after the wear to a certain extent, the friction between the brake pads and the brake disc increases, producing frictional noise. This is one of the direct methods of judgment. When you hear friction noise, it indicates that the brake pads need to be replaced.
Braking sensation: When the brake pads wear out, the brake pedal becomes soft and the feeling of stepping on it is not as tight as before. When you feel a noticeable decrease in the force feedback when the brake pedal is pressed, it indicates that the brake pads may have worn to the point where they need to be replaced.
Braking distance: Severe wear on brake pads can lead to a significant increase in braking distance, requiring a longer braking distance to stop the car. If you find that the braking distance is significantly longer than before, it may indicate that the brake pads are severely worn and need to be replaced immediately.
Brake pad thickness: The thickness of the brake pad can be determined by checking the brake pad. Worn brake pads are usually thinner than new brake pads. You can remove the car tires and determine whether the brake pads need to be replaced by checking the thickness of the brake pads. Generally speaking, the thickness of brake pads should be at least 3mm or more. If it is below this value, it needs to be replaced.
Brake pad wear indicator: Some cars have wear indicators on their brake pads. The wear indicator is a metal plate that is connected to the base of the brake pad. When the brake pads wear to a certain extent, the metal plates will start to come into contact with the brake discs, making a harsh braking sound. This is also a method to determine the degree of brake pad wear.
