What Are the Reasons for Abnormal Noise When Braking While Driving?

[CalebDella]

Driving when braking abnormal noise reasons are as follows: Brake pad break-in: Among them, the break-in of the brake pads is a very important part. Newly replaced brake pads also need to be broken in to better integrate with the old disc. Solution: Frequent driving for break-in. Debris ingress: While the vehicle is moving, many tiny sand particles enter between the pad and the disc, causing friction and abnormal noise. Solution: Flush the brake disc. Brake system malfunction: Missing or damaged fixing screws of the brake disc can also cause abnormal braking noise. Solution: Replace the brake disc, regular inspection and maintenance.

I've been driving for nearly thirty years and often encounter various strange noises when braking. The most common causes are worn brake pads or hard debris getting stuck, such as small stones from the road or rusted metal fragments. Especially after rain, when the brake discs are damp and prone to rust, stepping on the brakes upon starting the car can produce a squeaking sound, which usually wears off after driving for a while. It could also be due to a lack of lubrication in the brake system, leading to loud friction noises between components. Long-term neglect can even damage the brake discs, making replacements costly. I always remind myself to check the brake pad thickness and clean off dust every month to avoid major issues and safety risks in the future. In short, addressing small problems early is more cost-effective—don't wait until the noises worsen to act urgently.

I just bought a new car and encountered a loud clunking noise when braking, which scared me so much I almost didn't dare to drive. After asking friends, I learned it might be due to worn-out or cracked brake pads, or mismatched materials in new pads. Loose wiring or calipers could also cause parts to rattle when braking. Rust after rain or overnight dew can lead to screeching sounds. Later, at the repair shop, the mechanic said such issues usually cost just a few dozen dollars to fix, but early inspection is crucial to avoid safety hazards. Now, any strange noise makes me nervous, but I know timely action is key. I advise everyone not to delay and to get a reliable shop to check it out.

As a parent with children at home, I pay extra attention to safety when there are strange noises while braking. Common causes include uneven brake discs or dust accumulation, which can produce sharp squealing or rattling sounds when braking hard. It could also be that the brake components are worn too thin, and not replacing them in time will reduce braking effectiveness. What worries me most is the impact on the safety of family trips, so I perform simple weekly checks on the tires and brakes. On rainy days, I'm especially cautious about moisture and rust issues—if I hear any unusual sounds, I stop the car safely to inspect. Regular maintenance helps avoid risks like sudden brake failure.
