What are the causes of abnormal brake noise during vehicle driving?
6 Answers
Vehicle driving abnormal brake noise causes are: 1. Brake disc or brake pad rust; 2. New brake pads; 3. Excessive wear of brake disc and brake pads; 4. Brake pads installed backwards or model mismatch; 5. Use of inferior or overly hard brake pads; 6. Abnormal brake caliper or lack of brake fluid; 7. Foreign objects between brake drum/disc and lining. Solutions for vehicle driving abnormal brake noise: 1. Apply butter or special lubricant at the connection between brake pads and caliper; 2. Regularly inspect and replace brake pads; 3. Periodic brake adjustment; 4. Avoid frequent brake usage.
I've encountered brake squealing several times, usually caused by excessively worn brake pads where the metal parts start grinding against the rotors, producing sharp screeching sounds. Another common reason is rust buildup on the rotor surface, especially after prolonged parking in rainy conditions - the scraping of rust causes noise. Sometimes small stones or debris stuck between pads and rotors can also create rattling noises while driving. Never ignore these sounds. Continuous high-pitched squealing likely indicates pad replacement is due, as delayed action may damage the rotors and lead to costlier repairs. I regularly check brake pad thickness using a coin gauge - anything below 3mm requires replacement. Occasional mild noise during cold starts might be normal, but frequent abnormal sounds warrant attention. Having technicians inspect the braking system during routine maintenance can prevent many issues.
When it comes to brake noise, I guess many car owners have had headaches over it. Common causes include uneven or scratched brake rotors, which create vibrations and noise during friction. Loose or stuck springs in the calipers can prevent the brake pads from retracting properly, leading to continuous grinding noises. Newly replaced brake pads that haven't been properly bedded in may also produce high-pitched squealing, which usually disappears after a few hundred kilometers of driving. My friend encountered this issue when he DIY-replaced his brakes—misalignment during installation caused the problem. It's also important to check the brake fluid level; insufficient fluid or air in the system can cause abnormal braking and noise. I recommend first observing when the noise occurs—whether during turns or straight driving, light or hard braking—as this can help the repair shop quickly diagnose the issue. Don't wait until the brakes fail; safety always comes first.
I always feel worried when I hear my brakes squeaking while driving. Simply put, common causes include worn brake pads or dust/grease buildup causing squealing during friction. It could also be due to rust on the brake discs after rain, making a clicking sound when starting. Pay attention to the frequency of the noise - occasional sounds aren't alarming, but persistent ones require inspection. For safety, I immediately slow down and stop, turning on hazard lights to check for foreign objects around the tires. If unsure, go straight to the repair shop - don't risk long drives. Regularly spraying brake cleaner during car washes can prevent rust. Remember to maintain your vehicle regularly - cars are partners that need proper care for peace of mind.
Brake noise is really annoying. From a cost-saving perspective: Most of the time, it's caused by brake pads worn to the limit, where the metal backing plate grinds against the rotor—replacing them with a set of genuine ones costs just a few hundred bucks, much cheaper than ruining the rotor. Or, if the brake rotor is too thin or uneven, grooves can form and cause noise, requiring resurfacing or replacement. A stuck caliper piston can also lead to persistent noise, which might be fixed with lubrication. I ignored it once, and later the braking distance increased, nearly causing an accident—so now I schedule an inspection at the first sign of noise. A quick reminder: don’t cheap out on low-quality pads; their poor material easily causes squealing. Check brake pad depth monthly—prevent minor issues from becoming major repairs.
Having driven for many years, brake noises are mostly due to aging issues. When brake pads wear thin or the material hardens, the friction noise increases. In humid weather, rust on the discs and pads worsens, especially after parking outdoors for a few days, resulting in a clicking sound when starting. In winter, low temperatures cause components to contract and stick, also leading to noises. Regular maintenance is key—I check the brake system every six months, inspecting pad and disc wear, and lubricating the calipers. I also pay attention to wheel balance, as misalignment can indirectly cause noise. Developing the habit of using light braking at low speeds to break in new parts ensures the problem rarely recurs, guaranteeing safe and worry-free driving.
