What Causes the Squeaking Sound When Braking a Car?
1 Answers
There are several specific reasons why a car makes a squeaking sound when braking: 1. Use of low-quality or overly hard brake pads. If the brake pads are too hard or of poor quality, they will produce a squeaking noise when rubbing against the brake disc during braking. 2. Presence of sand or other foreign objects between the brake pads and brake disc, which can cause a squeaking sound during braking. 3. Severe wear of the brake disc. Using low-quality brake pads or having foreign objects inside the brake disc can lead to wear on the brake disc. If the brake disc is excessively worn, stepping on the brake will produce a squeaking noise. 4. The brake pads emit a warning sound. The brake disc becomes thinner with use, and if the wear reaches the threshold of the warning line, it will emit a squeaking alarm sound.
