Why does the car make a squeaking sound when braking?
4 Answers
Possible causes include poor quality brake pads, foreign objects in the brake disc, or severe wear of the brake disc. Here is relevant information: 1. Poor quality brake pads: If the owner installed brake pads not provided by regular manufacturers or purchased inferior brake pads. Overly hard materials will produce squeaking sounds during braking and may also damage the brake disc. 2. Foreign objects in the brake disc: When driving on complex road conditions, wheels can easily fling up stones or other debris. Unlike drum brakes, disc brakes may trap stones between the brake pads and disc, causing abnormal noises during braking. 3. Severe wear of the brake disc: Sometimes the brake disc can be directly scratched by foreign objects or impacted by other objects, leaving pits on the surface. When brake pads rub against an uneven brake disc, they will also produce squeaking noises.
I've been driving for over twenty years and have always paid close attention to any squeaking sounds when braking. The most likely cause is rust or unevenness on the brake disc surface, especially noticeable after driving in humid weather. Another common issue is when the brake pads are nearly worn out, and the metal backing plate rubs against the brake disc, causing loud noises. Sometimes, small stones or dust get stuck in the brake components. While these problems might sound minor, they can actually reduce braking efficiency, making sudden stops at high speeds particularly dangerous. It's advisable not to attempt repairs yourself; instead, drive to a nearby repair shop immediately for a professional inspection and replacement of any faulty parts. Regularly cleaning the brake area during car washes can also help prevent such issues.
I'm a very cautious driver and particularly sensitive to brake noises when driving with my kids. The squealing sound usually comes from impurities on the brake pads or excessive wear, or it could be due to new brake pads needing a break-in period. I've noticed that if the car isn't driven for several days, a bit of rust forms on the brake discs, which becomes especially annoying when driving. This reminds me to pay attention to maintenance—I do a simple check every month and have a comprehensive inspection by a mechanic every six months. Don't wait until the noise gets worse to deal with it; addressing issues early ensures driving safety and avoids the scare of brake failure. For the long-term use of the car, I always try to avoid gravel roads and keep the brake area clean.
I just got my driver's license and often hear a weird squeaking sound when braking. At first, I thought the car was broken, but after checking, I realized it's mostly caused by dust or rust spots on the brake discs. A friend told me that if it's new brake pads, the noise will reduce after a few friction cycles. It could also be due to severely worn brake pads or loose calipers. For new drivers, don't worry too much—just take it to a repair shop, and the mechanics can easily fix it. Remember, this isn't an emergency, but don't delay either.
