What Causes Brake Noise in a New Car After Three Months of Use?
2 Answers
It may be due to the brake pads not being properly worn in yet, or some accumulated dust entering the brake disc. Brake pads not being properly worn in: If the new car hasn't been driven much, the brake pads might still be thick, causing some unusual noises when the brake pedal is pressed. Generally, new cars require a break-in period, and it usually takes about 300-500 kilometers of driving before the brakes reach a stable condition. Accumulated dust entering the brake disc: Unusual noises from the brakes in a new car could also be caused by accumulated dust entering the brake disc. In such cases, pressing the brake pedal will produce a particularly harsh sound. However, this isn't a major issue. Simply washing the car and firmly pressing the brake pedal a few times should resolve it. After purchasing a new car, it's essential to test drive it in an open area first. Ensure there are no issues with the car before making the final payment. If you notice any unusual brake noises, report them to the salesperson immediately. Let the salesperson assist in either replacing the car or solving the problem, and avoid attempting any repairs on your own.
I just bought a new car about three months ago, and it keeps making squeaky noises when braking, which makes me a bit nervous. It's normal for a new car's braking system to require a break-in period—the brake pads might be too hard or not fully adapted yet, causing some noise. It could also be due to poor road conditions where sand or dust has gotten stuck, making noise when the rotors and pads rub. Additionally, if the screws weren’t tightened properly during installation, looseness could cause unusual sounds. With the recent rainy and humid weather, wet brake rotors might also amplify the noise. A friend taught me to check the tires and rims for obvious dirt, but since the car is still under warranty, safety comes first. I’ll just drive it to the 4S shop for a professional inspection and free service—better not skimp on small issues that could lead to bigger problems.
