Is It Normal for New Car Brakes to Make Noise?
2 Answers
It is normal for new car brakes to make noise as the brake discs and pads need a break-in period. The function of brakes is to slow down and stop the vehicle. Their working principle involves converting the kinetic energy of the moving vehicle into thermal energy through friction between the brake pads and brake drums, as well as between the tires and the ground, thereby bringing the car to a halt. Methods for brake maintenance include: 1. High-temperature protection to prevent corrosion of the brake system, avoid brake pads from seizing due to high temperatures, and eliminate brake squealing; 2. Cleaning oil stains, dirt, and friction dust from brake discs, drums, and any components to ensure good heat dissipation of the brake discs; 3. Regularly replacing brake fluid; 4. Periodically checking the thickness of brake pads or shoes.
New car brake noise is actually quite common. Many new cars may produce slight noises when braking initially, such as squeaking or mild friction sounds. This is mainly due to the break-in period between brake pads and rotors. New components have rougher surfaces that require a few hundred kilometers of driving to properly wear in for daily use. If it doesn't affect braking performance (the car can still stop steadily), the noise usually disappears after some driving. However, pay attention to abnormal situations - if the noise is particularly loud, produces metal scraping sensations, or persists for too long, there might be issues like misaligned brake pads, trapped debris, or manufacturing defects. For safety, I'd recommend new car owners not to ignore it and promptly visit authorized dealerships or professional repair shops for inspection, especially since new vehicles are under warranty where repairs may be free while preventing bigger troubles. As a side note, try to avoid hard braking during the break-in period to reduce the likelihood of noise occurrence.
