What Causes the Squeaking Noise When Braking at Low Speeds?
2 Answers
Low-speed brake squeaking can be caused by: 1. Excessive wear of the brake disc and brake pads; 2. Improper installation of the brake pads; 3. Foreign objects on the brake pads or brake disc; 4. Poor caliper reset leading to prolonged friction between the disc and pads. Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, or other transportation tools and machinery. Solutions for low-speed brake squeaking include: 1. Applying butter or specialized lubricant to the connection between the brake pads and the brake caliper; 2. Regularly inspecting and replacing the brake disc and brake pads; 3. Reinstalling the brake pads.
I've encountered the issue of abnormal noise when braking at low speeds several times, and it's quite annoying. Most of the time, it's because dust or small stones are stuck on the surface of the brake pads, causing increased friction and a creaking sound at low speeds, especially after washing the car or during rainy days when the brake discs are prone to rust and produce noise. Another common reason is severe wear on the brake pads; when the thickness becomes too thin, the metal backing plate comes into contact with the brake disc, resulting in a sharp screeching sound. During my last inspection, I found that this problem occurs frequently in long-term city driving, particularly in scenarios with frequent braking. If the abnormal noise persists, it's best not to ignore it. Clean or replace the brake pads early to avoid damaging the brake discs. Long-term neglect can lead to decreased braking performance and affect driving safety, so I recommend checking the condition of the brake pads every six months as a preventive measure.
