Why Does a New Car's Brake Make Abnormal Noises?
2 Answers
Here are the main reasons why a new car's brake makes abnormal noises: 1. Generally, abnormal noises occur when the brake pads wear thin. You should check if the brake pads are severely worn. 2. The abnormal noise in a new car's brake might be caused by different materials of the brake pads. It is advisable to visit a car repair shop promptly to identify the specific cause of the noise. 3. Since the brake pads of a new car need to be broken in, abnormal noises may occur during this process, which is normal. The noise will disappear after driving a few hundred kilometers. 4. In windy weather conditions, dust from the air may enter the brake pads, which can also cause abnormal noises. In this case, pressing the brake firmly several times can help eliminate the noise.
When I first got my new car, the brakes made some squeaking noises. At first, I thought it was a major issue, but later I learned that this is a common phenomenon with new cars. New brake discs have an anti-rust coating or slight rust, especially after being parked in humid weather. The brake pads are new and made of harder material, so initial friction can cause noise. My experience is that after driving 100-200 kilometers, the noise naturally reduces or disappears, just like new shoes need some time to break in. Don’t worry too much, but pay attention to safety. If the noise doesn’t decrease but instead increases, or is accompanied by vibrations or reduced braking force, you must immediately go to the 4S shop to check if the brake system was improperly installed or if there are foreign objects stuck. New cars need a gentle break-in period. It’s recommended to avoid sudden braking for the first 500 kilometers to allow the components to operate smoothly. Handling it this way saves worry and ensures driving safety.
