What is the reason for the circular friction sound during low-speed driving?
2 Answers
The reasons for the circular friction sound during low-speed driving are: 1. If there is no friction sound when braking, but there is a friction sound during normal driving (without stepping on the brake), it can basically be determined that it is the friction sound between the brake pads and the brake disc; 2. The brake disc is deformed, the newly replaced brake disc has not yet been worn in, or there is a foreign object between the brake pads and the brake disc; 3. If the friction sound occurs at the connection between the transmission and the engine, it may be abnormal noise caused by damage to the clutch plate or release bearing. If the friction sound comes from inside the transmission, it may be caused by abnormal wear of the first or second gear. In this case, you can only go to a 4S store or a professional auto repair shop to have professionals solve the problem.
When I first started driving, I also encountered this kind of issue. At low speeds, I heard a rhythmic friction sound, like the feeling of tires spinning on the ground. Later, I consulted a friend and realized it might be a tire problem, such as uneven rubber wear or small stones stuck in the tread, which can produce that kind of noise when the wheels rotate. It could also be loose wheel hub bearings—those can cause increased friction at low speeds, resulting in a continuous cyclic sound. Sometimes, it's misaligned brake pads fighting with the brake disc, which can create a popping noise. I must remind you, although these sounds may seem minor, they can affect safety. I recommend going to a car wash or repair shop as soon as possible to check the tires and chassis. Don’t try to fix it yourself to avoid causing an accident.
