What to Do About Brake Noise in the New Jetta?
1 Answers
Brake noise in the new Jetta may be caused by the break-in period of a new car, newly replaced brake pads after rainy days, or sand and stones entering the brake discs. Here are the specific reasons for brake noise: 1. Brake noise in a new car: This is generally normal as the car is still in the break-in period, and the brake pads and discs have not fully worn in. Minor friction sounds may occur, but the noise will naturally disappear after driving for some time. 2. Noise from newly replaced brake pads: After installing new brake pads, uneven contact between the edges of the pads and the discs can cause noise. To prevent this, the edges of the new brake pads can be smoothed before installation to avoid scraping against the raised parts of the brake discs. 3. Noise after rainy days: Most brake discs are made of iron and are exposed to the elements. After rain or washing, rust may form on the discs, causing noise when the vehicle is started again. This happens because the rust causes the discs and pads to stick together. The noise will stop after driving and applying the brakes a few times to remove the rust. 4. Noise due to sand or stones in the brakes: If foreign objects like sand or small stones get between the brake pads and discs, a sharp squealing sound may occur when braking. Continuing to drive normally will usually dislodge the particles, and the noise will disappear.
