Why does the brake make a creaking sound when released?

[DeGavin]

The reasons for the creaking sound when releasing the brake: 1. False fault: When slowly releasing the brake pedal, the engine already has enough power to drive the car forward, but the brake is not fully released. The moving wheels are held back by the brake system, naturally causing abnormal noise. 2. Real fault: The brake disc and brake pads stick together due to rust, causing abnormal noise. Nowadays, many brake pads are made of semi-metallic materials, containing a large number of metal fibers. Sometimes metal particles form, producing a harsh sound when pressing or releasing the brake. This situation usually disappears after driving for a while. If it persists, it may be due to poor manufacturing quality. It is recommended that the owner replace the brake pads in time to avoid scratching the brake disc.

A couple of days ago, I was driving and heard a loud creaking noise when I released the brake, which startled me. This usually happens during significant weather changes, like on rainy or cold days, when the brake disc surface rusts. The brake pads then rub against the rusty part when releasing the brake, causing that noise. Normally, it's not a big issue, but if it keeps happening, it's not good. Once, I ignored it, and my braking efficiency dropped—I almost rear-ended someone. I recommend paying attention to it regularly. After parking, don’t pull the handbrake too tight to prevent further rusting. Check the brake pad thickness and brake disc flatness every six months. Replacing them early when you notice wear saves money and ensures safety. Also, when parking on a slope, try to reduce brake pressure to avoid loosening components and causing extra noise. In short, don’t take it lightly—a basic inspection at a repair shop usually costs just a few bucks.

I've been driving for many years and have dealt with quite a few of these squeaky brake issues. Common causes include the metal backing plate of worn brake pads rubbing against the brake disc, or uneven brake discs causing spot friction. Some car designs with harder materials are more prone to noise, especially after rain when rust spots are more noticeable. It's important to distinguish: if it's drum brakes, it might be loose springs; for disc brakes, check the caliper installation. I recommend avoiding parking on slopes with the handbrake engaged to reduce rust buildup; check the brake depth yourself, and replace them if it's less than 5mm. If you've installed low-quality brake pads, they're more likely to cause problems—choose reputable brands for better performance. Don't delay on safety; if the noise is frequent, get it repaired promptly to prevent the high risk of brake failure.

My old car makes a creaking sound when I release the brake, mainly related to the brake pads. Frequent braking in daily driving accelerates brake pad wear, and when the metal part is exposed, it causes friction noise; rust on the brake disc can also amplify this issue. Fortunately, most cases are manageable. Cleaning brake dust during car washes can help alleviate the problem. Regularly replacing brake pads, typically checking the front wheels every 30,000 kilometers, saves money and ensures peace of mind. Don't let the noise grow louder and affect your driving mood—fix it early.

Every time I start driving and release the brake, it makes a creaking noise, which really affects my mood. After analysis, it's commonly caused by loose brake system components or rust, such as uneven edges on the brake discs causing friction noise. Once in cold weather when I hadn't driven for long, this happened, but after cleaning and removing the rust, it was fine. It's recommended to develop good habits: park in a garage after rain to avoid moisture, and take short drives weekly to use the brakes a few times to prevent rust. If the noise becomes severe, first check that the brake pad thickness hasn't exceeded the limit—replacing a set early costs just a few hundred bucks and is much safer. Don't delay until a major issue arises, which would cost a fortune to fix.

When I drive and hear a creaking sound when releasing the brake, I always worry about major car issues. In fact, it's a common fault caused by hardened brake pads or slight deformation of the brake discs leading to friction, especially more likely in extremely cold regions. Regular maintenance is key: perform brake inspections and replace wear-prone parts every 20,000 kilometers; park on level ground to reduce handbrake pressure and prevent rust. Once, I ignored the noise, and later the brakes became sluggish, increasing fuel consumption and costs. Paying attention to sound changes in daily use can prevent major repairs, saving both money and hassle.
