What Causes Abnormal Noise in Car Brakes?
2 Answers
The causes of abnormal noise in car brakes are: 1. Rust on brake discs or brake pads; 2. New brake pads; 3. Excessive wear of brake discs and brake pads; 4. Incorrect installation or mismatched model of brake pads; 5. Use of inferior or overly hard brake pads; 6. Abnormal brake caliper or lack of brake fluid; 7. Presence of foreign objects between the brake drum or disc and the shoe. The solutions for abnormal noise in car brakes are: 1. Apply butter or specialized lubricant at the connection between the brake pad and brake caliper; 2. Regularly inspect and replace brake pads; 3. Regularly adjust the brakes; 4. Avoid frequent use of brakes.
As someone who enjoys driving for leisure, I'm quite concerned about brake noises. The most common issue is when the brake pads wear out completely, and the metal backing plate starts rubbing against the rotor, producing an ear-piercing squeal like metal grinding – it's really annoying. Or sometimes the brake rotor gets dirty, with accumulated dust and grit, especially after driving post-rain when the wheels dry out, causing similar sounds. Occasionally, it's due to lack of lubrication in the caliper slide pins, which become dry and noisy over time. I remember one time my car had persistent noise, and after much troubleshooting, we found the brake pads were installed crooked – replacing them fixed it. Never underestimate this issue; brake system failure can be dangerous, like failing to stop suddenly on the highway. So, I recommend regular brake inspections at a professional shop to check pads and rotors. Also, rinsing wheel dust during car washes helps prevent buildup. Addressing issues early saves money and hassle – safety is more important than anything.
