What Causes the Creaking Sound When Slowly Releasing the Brake in an Automatic Transmission Car?
3 Answers
Automatic transmission cars make a creaking sound when the brake is released too slowly during startup. Reasons for the sound: When the brake pedal is slowly released, the engine already has sufficient power to drive the car forward, but the brake hasn't been fully released yet. As a result, the moving wheels are held back by the brake system, naturally producing an abnormal sound. Simply releasing the brake a bit faster can resolve this issue. Requirements for driving an automatic transmission car: As the name suggests, an automatic transmission doesn't require the driver to manually shift gears. The vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Generally, automatic transmission cars have six gear positions, arranged from top to bottom as: P, R, N, D, S, L. When starting an automatic transmission car, pay attention to how you press the accelerator pedal (gas pedal). It is not allowed to press the accelerator hard while still stepping on the brake or even before releasing the handbrake. It is also not allowed to press the accelerator first and then shift into P or N gear. Additionally, you should not press the accelerator while moving the gear lever.
I usually enjoy tinkering with cars. The creaking sound when slowly releasing the brake on an automatic transmission is quite common. The main cause is usually rust on the brake discs, especially when starting to drive after rain or in humid conditions—the friction of the rust layer on the surface produces that noise. Uneven wear on the brake pads or debris stuck in between can also cause creaking, like when driving on dusty roads where accumulated dust can lead to this issue. If the caliper components are loose, they may move back and forth when braking, creating noise, though this is a rarer scenario. I recommend paying attention to it—if the sound disappears after driving a few kilometers, it’s fine. But if it persists, get your brake system checked at a repair shop immediately to avoid small issues turning into big problems. Safety comes first—brake failure is no joke. A friend of mine ignored it and ended up spending a lot more on repairs later. With proper maintenance, daily driving becomes smoother, and saving money and hassle isn’t just a dream.
I've been driving for over a decade, and the creaking sound when slowly releasing the brake pedal on an automatic transmission is indeed annoying. It's usually caused by rust on the brake discs, especially noticeable when starting the car in humid weather or after overnight parking. I've encountered this several times. A simple solution is to gently press the brake pedal a few times while stationary to see if it can remove the rust layer. If that doesn't work, you should check for brake pad wear or dust accumulation – don't underestimate these issues as they affect safety. Driving habits matter too; frequent driving on rough roads can easily get dust into the brake system, causing noise. Don't panic right away – most of the time, the sound stops after driving for a while. However, I recommend getting a professional inspection immediately if the noise occurs frequently. Don't delay until it becomes a major issue. Replacing new brake pads isn't expensive, and regular minor maintenance can significantly reduce such problems, ensuring safe and trouble-free driving.
