What to Do When There's Noise When Braking?
1 Answers
If it's a new car, it's normal to hear some noise when braking, and it should go away after driving for a while. If the car has been driven for a long time, the brake discs or brake pads might be rusty, and you can remove them to sand off the rust layer. Below are specific solutions for noise when braking: 1. Rust on brake discs or brake pads. After parking for a long time, especially in humid or rainy weather, some rust or dirt may appear on the brake discs or pads. This can usually be resolved by driving for a while, or you can apply butter or specialized lubricant to the connection between the brake pads and calipers. 2. New brake pads. New cars or recently replaced brake pads may produce similar noises. New brake pads and discs require a break-in period, and such noise during braking is completely normal. However, if the noise persists after driving for an extended period, there may indeed be an issue. 3. Excessive wear on brake discs or pads. Both brake discs and pads are high-wear items, as they constantly rub against each other during braking. Over time, they naturally wear out, and excessive wear can lead to noise. Therefore, regular maintenance and replacement are necessary. Typically, brake pads should be replaced every 60,000–80,000 kilometers, while brake discs should be replaced every 100,000–120,000 kilometers.
