Why does a new car's brakes make a squeaking sound?
1 Answers
New car brakes making a squeaking sound is due to the friction between the brake pads and discs during the wear-in period. This noise will disappear after some driving as the parts properly seat, which is completely normal. Common causes of brake noise include: 1. Break-in period for new cars - Brake pad bedding is an important process, typically requiring several hundred kilometers before optimal braking performance is achieved; 2. Newly replaced brake pads also need to wear in to properly match with old rotors; 3. Tiny particles may get between pads and rotors during driving, causing noise through friction; 4. Missing or damaged brake rotor mounting screws; 5. Malfunctions in the brake system.
