How to Deal with Abnormal Noises When Braking?

When abnormal noises occur during vehicle braking, the common causes include the following: 1. New car making noise when braking: The brake pads and rotors of a new car have not yet been fully broken in, which can sometimes result in a "squeaking" friction sound. This is normal, and the noise will naturally disappear after some use. 2. Noise after replacing brake components: After installing new brake pads, incorrect installation may cause abnormal noises. Common installation errors include mounting the brake pads upside down, where the metal side contacts the rotor, leading to noise. 3. Noise due to brake rotor issues: Prolonged use can cause deep grooves on the rotor surface or deep steps at the edges. Uneven contact between the brake pads and rotor can produce noise. In such cases, the rotor needs replacement or resurfacing using a brake lathe. 4. Noise caused by sand or debris in the brakes: If foreign objects like sand or small stones get between the brake pads and rotor while driving, a sharp hissing sound may occur. Continuing to drive normally will usually dislodge the debris, eliminating the noise. If the noise persists, the wheel may need removal to extract the debris. 5. Noise during hard braking: When braking sharply, a clicking sound accompanied by pedal vibration is normal and indicates ABS activation.

Brake noise should never be ignored. When I encounter this situation, I usually first check the thickness of the brake pads. If they're worn too thin, they need to be replaced - generally anything below 3mm is considered dangerous. Next, there might be debris or rust on the brake discs. Wiping them with a cloth or spraying some cleaner might eliminate the noise. It's also important to check if the brake caliper is stuck - insufficient lubrication often causes squeaking, so when doing DIY maintenance, be sure to use specialized grease. For safety, if the noise gets louder during deceleration, immediately find a safe place to stop and inspect - don't risk driving and causing an accident. Make it a habit to have your brake system inspected by a repair shop every six months to prevent small issues from turning into major problems.

Hearing abnormal brake noises immediately puts me on high alert, as it directly relates to driving safety. Possible causes include excessively worn brake pads or caliper issues. You can perform simple checks like measuring pad thickness or cleaning brake discs with tools, but for complex situations such as voltage testing or part replacements, it's best to consult professionals. If abnormal noises occur on highways, promptly turn on hazard lights, pull over, and seek assistance—never risk continuing to drive. Regular maintenance is crucial; a monthly visual inspection of the brake system can help prevent potential hazards by addressing issues early.

I'm the type who drives very carefully, and every time there's a strange noise when braking, it really bothers me. Last time my car made a squeaking sound, I found out the brake pads were worn out—spending a bit to replace them solved the issue. Sometimes, it's just sand or metal shavings stuck in the brake disc, which can be removed by blowing them out with compressed air. If the problem is more serious, like the noise persisting even when braking hard, it's best to take it to a professional repair shop—it could be a stuck caliper or wiring issue. Don't just focus on saving money; ignoring these unusual sounds could lead to brake failure, which is too risky. I make it a habit to get regular maintenance, checking the brake fluid and component wear, which saves a lot of trouble down the road.

Brake noise is quite common, and I usually start by checking it myself. For example, see if the brake pads are lacking lubrication or have dust on them, and try wiping them with a cloth. If that doesn't work, it's likely time to replace the pads. From a safety perspective, if the noise gets loud, pull over immediately and don't force the drive. It's recommended to visit a reliable auto repair shop for diagnosis to avoid causing further damage by tinkering yourself. When driving, pay attention to the road surface and avoid slowing down in muddy areas to reduce the chance of debris getting in.
