What are the reasons for brake noise in Jetta VS5?
2 Answers
The reasons for brake noise in Jetta VS5 are as follows: Reason 1: It is normal for a new car to have brake noise, which usually disappears after a running-in period of more than 200 kilometers, so there is no need to worry. Reason 2: Replacing new friction pads or new brake discs may cause noise if the new brake discs cannot immediately achieve good running-in with the friction pads. Reason 3: Sometimes, hard substances like sand or gravel entering the gap between the brake disc and the brake pad can also cause noise, usually during the initial driving phase. Such noise can generally be ignored, as it often occurs after driving through water or off-road on muddy roads, where hard sand or gravel gets into the gaps of the braking mechanism, causing jamming and resulting in brake noise when the braking system is engaged. Reason 4: Poor fixation of the brake caliper or brake disc can also lead to brake noise and uneven brake wear. Reason 5: Excessive wear of the brake disc or breakage of the brake pad, even if not heavily worn, can also cause brake noise.
I've encountered brake squealing issues multiple times while driving my Jetta VS5, with the sound resembling a mouse's squeak. It's mainly due to brake pad problems, such as excessive wear or hard material, especially noticeable on rainy days or in low temperatures. Even when the car was new, the brake pads weren't properly broken in, causing annoying squeaks with just a few presses. Additionally, rust on the brake discs or debris like small stones stuck in the gaps can also cause noise. Last time I went for repairs, the mechanic mentioned that insufficient lubrication of the calipers could lead to uneven friction, accelerating wear if not fixed. Safety is paramount; if you hear squealing, get it checked at a professional shop immediately, as prolonged braking distances can be dangerous, especially on highways.
