What causes the noise when releasing the brake at the start of a BMW X3?
2 Answers
This is a normal phenomenon for automatic transmission vehicles; the brake noise is due to the clearance in the brake pads. Below is relevant information about the BMW X3: 1. Model: The BMW X3 is an SUV model with unique characteristics, introducing the new concept of an SUV Sports Activity Vehicle and equipped with BMW's patented xDrive intelligent all-wheel-drive system. 2. Design Style: The BMW X3 combines the distinctive proportions of a Sports Activity Vehicle with classic and innovative design elements, featuring a fresh and youthful exterior while emphasizing the robust and powerful design traits of the BMW brand. Additionally, the BMW X3's interior can accommodate five people along with ample luggage or sports equipment, providing greater convenience for travel. Currently, the BMW X3 is the latest model in its series.
After driving my BMW X3 for a while, I also noticed that there is often a squeaking noise when releasing the brake at startup. This issue is quite common and usually not a major fault. For example, if the brake pads are nearly worn out or have some sand and dirt stuck on them, they can produce friction sounds; or if the brake discs rust after rain, there will be noise when releasing the brake at startup. It could also be due to poor retraction of the brake pads, causing slight adhesion. I suggest first checking the thickness of the brake pads yourself—if they are too thin, they should be replaced. Additionally, pay attention to rinsing the wheel hubs when washing the car to keep them clean. If the noise persists, it’s better to have it checked at a professional shop—it won’t cost much and can prevent bigger troubles. This problem is more likely to occur in cold weather, but regular maintenance can reduce its occurrence.
