Why Does the New Car's Brake Make Noise?

[AllisonFitz]

Here are the reasons why a new car's brake may squeak: 1. Severe wear on the brake disc. If hard foreign objects get between the brake pad and the brake disc, it can cause abnormal wear on the brake disc. If the brake disc is excessively worn, you may hear a squeaking noise when braking. 2. Brake pad warning. Many people don't know how often brake pads should be replaced. In fact, there is no strict rule on mileage for replacement—just replace them when they become thin. Some brake pads have electronic warnings, while some lower-end cars use warning tabs. If the brake pad wear reaches the warning line, it will emit a squeaking alarm sound, indicating that immediate replacement is needed. 3. Use of low-quality or overly hard brake pads. If low-quality or overly hard brake pads are used, they may produce a squeaking noise when rubbing against the brake disc during braking. Therefore, it is essential to use high-quality brake pads when replacing them. 4. Sand or foreign objects between the brake pad and brake disc. During normal driving, it's inevitable to pass through some complex road conditions. Due to the unique design of disc brakes, sand and foreign objects may enter between the brake pad and brake disc, causing abnormal noises when braking.
