How to Solve the Noise When Braking?

When the ABS is activated by sudden braking, it may produce abnormal sounds, which is a normal phenomenon. In this case, simply press the brake pedal firmly to the maximum. Below is some information about ABS: 1. The working process of ABS is actually a cycle of locking and releasing, keeping the vehicle in a state of near-lock rolling. 2. The braking performance of a vehicle is mainly evaluated from the following three aspects: (1) Braking efficiency, i.e., braking distance and deceleration; (2) Consistency of braking efficiency, i.e., resistance to heat or water fade; (3) Directional stability during braking, i.e., the vehicle's ability to avoid deviation, skidding, or loss of steering during braking.

Every time I hear a squeaking sound when I step on the brakes while driving, I feel uneasy because it usually indicates severe brake pad wear. There's a small metal piece on the brake pad that scrapes against the brake disc and makes noise when the material wears thin. It could also be due to foreign objects like small stones stuck in the wheels. You can first find a safe place to stop and try to check the thickness of the brake pads. If it's below 2-3 millimeters, you need to replace them immediately. I remember once ignoring a slight noise, and as I kept driving, the brakes became less responsive, almost causing an accident. Later, I went to a repair shop and spent some money to fix it. During regular maintenance, it's important to periodically inspect the brake system, replace the pads or resurface the brake discs every 10,000 kilometers or so, and develop a habit of braking smoothly to avoid sudden stops, which can effectively prevent problems. Brakes are a matter of life and death, so don't delay addressing issues—ensure safe driving.

I'm quite familiar with the issue of brake squealing. It's mostly caused by uneven or rusted brake disc surfaces leading to friction noise, or poor-quality brake pad materials causing abnormal sounds. As someone who enjoys tinkering with cars, whenever I hear such noises, I first clean the wheels and brake discs to see if debris can be removed. If the noise persists, I check for fine grooves on the discs that might need smoothing. However, for a more reliable solution, it's advisable to visit a professional repair shop. They can use tools to detect loose components or insufficient fluid levels, ensuring everything is in perfect order. I remember once after driving in the rain, the squealing got worse—turned out to be rust caused by water accumulation, and it stopped after cleaning. For prevention, avoid parking in waterlogged areas and regularly check the brake fluid and the stability of connecting parts. This approach not only solves the problem effectively but also saves money and hassle in the long run.

Hearing the brake squeal makes me nervous. A common cause is excessively worn brake pads, where the wear indicator triggers a squealing sound to warn you. Continuing to drive poses a high risk of brake failure, so don’t delay once you notice it. Pull over and do a quick check of the brake pad thickness yourself if possible. If not, head straight to the repair shop. Safety comes first—don’t ignore it to save a few bucks. I ignored it once and nearly rear-ended someone—a lesson learned the hard way. Brake issues need immediate attention to ensure safe driving.
