What is the problem when there is a sound when stepping on the brake?

The reasons for the sound when stepping on the brake: 1. Normal activation of ABS. 2. When stepping on the brake in an automatic transmission vehicle, the gear makes a clicking sound. The main reason for the sound may be the electronic linkage between the brake system and the automatic transmission. 3. The brake system has a fault or a connecting component in the chassis has become loose. Below is an introduction to the brake: 1. The brake, also known as the braking system, refers to the action of stopping or reducing the speed of running locomotives, vehicles, other transportation tools, or machinery. 2. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install a corresponding brake shoe, belt, or disc on the machine base to generate braking torque under external force. 3. The brake device is a mechanical braking device that can slow down the speed, also known as a decelerator.
I find it quite common to hear noises when stepping on the brakes, mostly due to worn brake pads. That warning sound indicates the pads have thinned to the point of needing replacement. Continuing to drive with them will reduce braking effectiveness, which is quite dangerous. After rain or prolonged parking, rust on the brake discs can also cause grinding noises, but these usually disappear after driving a few kilometers. However, if the noise persists, it's best to check the braking system—don't skimp on maintenance and risk bigger issues. You can also inspect the brake pad thickness yourself—use a phone flashlight to check through the wheel gaps; if the pads are less than 3mm thick, they need replacing. Rinsing the brake discs during regular car washes can reduce noise caused by dust buildup and maintain braking responsiveness. Safety isn't something to take lightly—addressing issues early saves time and effort.
When driving with family, there's a noise when I step on the brakes, and I always think it's caused by worn brake pads. That metallic buzzing sound indicates the pads are almost worn out. Continuing to drive might increase the braking distance, and if emergency braking fails, it could lead to serious trouble. Sometimes, small stones stuck in the brake disc cause unusual noises, or rust on the brake disc after prolonged parking can also produce sounds. This situation occurs more frequently on rainy days, but not addressing it promptly might damage other components. I suggest not waiting and going to a professional repair shop as soon as possible to check the brake components. They will use tools to measure the thickness and wear condition. By the way, a poorly maintained braking system can increase fuel consumption. Using more gentle braking in daily driving can also help prevent minor issues.
