What are the causes of abnormal noise in car brakes?

The causes of abnormal noise in car brakes are: 1. During the break-in period of the brake disc; 2. Normal activation of the ABS system; 3. Foreign objects between the brake pads; 4. Rust on the surface of the brake disc; 5. Excessive wear of the brake pads or brake disc; 6. Assembly issues; 7. Problems with new brake pads. The brake is a mechanical braking device that can slow down the speed of the vehicle, also known as a decelerator. The car brake pedal is located below the steering wheel. Pressing the brake pedal causes the brake lever linkage to be pressurized and transmitted to the brake pads on the brake drum, clamping the brake disc to slow down or stop the vehicle. The manual brake of the car is located next to the gear shift, connected to the brake lever.
When I drive, the most common reasons for squeaky brakes are either the brake pads being worn too thin or small stones getting stuck. In summer, high temperatures cause the brake discs to expand from heat, or in winter, rust forms after rain, making the contact surface uneven and leading to unusual noises. My car had this issue last year, and a friend mentioned it could also be due to uneven friction from low-quality brake pad materials or temporary noise caused by water seeping in during car washing. If the sound is only slight during initial driving, it might be a break-in period issue; but if it persists, it should be addressed. Promptly cleaning the brake discs or replacing components can solve the problem. I’ve always believed regular maintenance is crucial—otherwise, accelerated wear could compromise safety. Last time I got it checked, the mechanic found the caliper was a bit tight, and after adjustment, the noise disappeared. Now, I make sure to avoid sudden braking on dusty roads to reduce the chances of squeaking.
