Why Does the New Car Make a Clicking Noise When Braking?

[Cora]

New car making a clicking noise when braking may be due to excessive wear of the brake disc and brake pads. Detailed reasons and solutions for the new car making a clicking noise when braking are as follows: Friction wear of brake pads and brake disc: Both the brake disc and brake pads are high-wear components. Each time the brakes are applied, these two parts rub against each other, leading to natural wear over time. When the wear becomes excessive, it can result in abnormal noises. Therefore, regular inspection and replacement are necessary. Replacement cycle for brake pads and brake disc: Generally, the replacement cycle for brake pads is 60,000 to 80,000 kilometers, while the brake disc should be replaced every 100,000 to 120,000 kilometers.

A new car making a clunking noise when braking is quite common. I experienced it too when I first drove my new car. Possible reasons include the new brake pads and rotors being in the break-in period, where friction between them can cause noise, which usually improves after a few hundred kilometers of driving. It could also be small stones or dust stuck in the braking system, causing a rattling sound when braking. Another factor might be installation issues, such as loose screws or misaligned parts, as new cars occasionally have minor defects from the factory. Weather also plays a role, as metal contracts in cold weather, making noise more likely. My advice is to drive for a few more days and observe. If the noise persists or gets louder, or if you notice reduced braking responsiveness, take it to the dealership immediately for inspection. Safety comes first—new cars have warranty coverage for free repairs, so don’t delay until something serious happens. Normally, gently applying the brakes can reduce noise and protect the car. Remember, break-in is a normal process, but stay alert for potential issues.

After buying a car, if the brakes make a clunking sound, as someone who often tinkers with cars, I would first check if it's a break-in issue with new components. There might be gaps between newly installed brake pads and discs. Contaminants like gravel stuck in the system are also common culprits, especially noticeable after rain or on dirty roads. Air bubbles or insufficient brake fluid can also cause unusual noises, particularly when pumping the brakes. Additionally, temperature changes causing materials to expand and contract can create extra noise. You can try lightly pressing the brakes several times in a row, which might help expel air bubbles or alleviate the issue. If that doesn't work, take it to a professional mechanic—DIY fixes on a new car can be too risky. Ensure safe driving by preventing minor issues from turning into major repairs. Develop a habit of regularly checking brake fluid and tires, and promptly clean off dirt for simple and efficient maintenance.

When my first new car made a clicking sound while braking, it scared me quite a bit. After researching, I learned it was a break-in issue—new brake systems need a few hundred kilometers to adapt. It could be due to trapped impurities or minor installation flaws. If the noise is too loud, go to the 4S store for a check—don’t ignore it. The sound disappeared after some driving, so it’s not unusual early on. Safe driving habits like gentle deceleration help reduce noise. Remember, new car warranties cover such issues.
