Why Do Car Brakes Make Noise?

[StRuth]

The reasons why car brakes make noise are as follows: 1. Severe wear of brake pads: This is usually caused by the brake pads reaching the warning line or being completely worn out. The noise is mostly a metallic friction sound and is relatively sharp. If accompanied by a decrease in braking effectiveness, this can almost certainly be identified as the cause. 2. Noise caused by the material of the brake pads: Generally, harder brake pad materials are more likely to cause this type of noise. In contrast, softer brake pad materials are less prone to such noise. However, softer materials wear out faster, resulting in a shorter replacement cycle compared to harder materials. 3. Improper installation of the braking system causing noise.
