How to Solve Brake Noise Issues?
2 Answers
Here are the solutions for brake noise issues: 1. High-pitched squealing noise from the brakes. Solution: Check if the brake pads are worn out. If they are, replace them. Brake pads have wear indicators (metal tabs) that produce noise when the pads are excessively worn, signaling it's time for replacement. 2. Noise from newly replaced brake pads. Solution: Have the brake pads resurfaced or sanded down. 3. Dull or muffled brake noise. Solution: Inspect the brake caliper for issues such as worn slide pins or missing spring clips, which may require professional repair. 4. Continuous brake noise. Solution: Check if the caliper is not retracting properly; inspect for foreign objects between the pad and rotor; examine if the brake rotor has grooves; and verify if the noise suppression shims are installed incorrectly.
I've been driving for several years and have encountered brake noise issues more than once. I remember once after coming back from camping in the mountains, the brakes made that harsh squealing sound when applied. At first, I thought it was normal wear. Later, upon self-inspection, I found that mud and sand had accumulated on the edges of the brake pads, and rust had formed after rain, causing the noise. The solution was quite simple: driving short distances sometimes wears off the rust. However, if the noise persists for more than a week, don't tough it out—get the brake pad thickness or disc surface evenness checked. Brakes are a safety issue; my neighbor once had a brake failure accident because he ignored this. I recommend drying the brakes after each car wash and having the shop use instruments to check them during regular maintenance—don't skimp on that small expense. Pay attention to abnormal sounds during daily driving; prevention is always better than cure.
