What does brake pad wear mean?

[DeBlakely]

What does brake pad wear mean: 1. During the use of a car, frequent braking causes the friction material of the brake pads to gradually wear down due to friction, leading to increasingly poor braking performance. If not replaced in time, it will eventually result in a complete loss of braking effect, affecting driving safety. 2. Brake friction pads also need to be replaced when worn to a certain extent to ensure braking performance is not compromised. Since brake system wear is influenced by various factors, it is best to check every 3,000 kilometers or so. Newly replaced brake pads require a certain break-in period to maximize their braking effectiveness. 3. Generally, the lifespan of brake friction pads is around 30,000 kilometers, but this figure is not absolute. The replacement cycle should be determined based on actual usage and individual driving habits. Developing a habit of regular inspections and timely maintenance is the most important.
