What Causes Abnormal Noise When Braking at Low Speed?
2 Answers
The causes of abnormal noise when braking at low speed are as follows: 1. Use of low-quality or overly hard brake pads: If low-quality or overly hard brake pads are used, they may produce abnormal noise when rubbing against the brake discs during braking. Therefore, it is essential to use high-quality brake pads when replacing them. 2. Foreign objects between the brake pads and brake discs: During normal driving, it is inevitable to pass through some complex road conditions. Due to the unique design of disc brakes, sand and foreign objects may enter between the brake pads and brake discs, causing abnormal noise when braking.
I've been driving for ten years, and it's quite common to hear noises when braking at low speeds. When the brake pads are worn down almost to nothing, they can make sounds during low-speed friction, especially when turning or coming to a slow stop. Newly replaced brake pads might also produce noise due to a break-in period, which usually goes away after a few hundred kilometers of driving. Another reason could be rust or dust buildup on the brake disc surface, particularly if the car hasn't been used for several days. Brake discs can also temporarily make noise after getting wet from driving through water. Don't underestimate these noises—they might be early signs of a loose brake caliper or a broken spring, so it's best to get them checked at a repair shop immediately. I remember one time I ignored it and almost rear-ended someone. Now, I make sure to regularly change the brake fluid and clean the brake system to prevent issues. Safety first—don't delay repairs.
