What causes the squealing sound when stepping on the brake?
1 Answers
There are five main reasons for the squealing sound when braking: 1. Severely worn brake discs: When brake pads rub against uneven brake discs, abnormal noises may occur. 2. Foreign objects in brake discs: When driving on complex road conditions, wheels can easily fling stones or other debris. 3. Poor quality brake pads: If non-standard manufacturer brake pads are installed or low-quality brake pads are used, the overly hard material will cause abnormal noises during braking and may damage the brake discs. 4. Severely worn brake pads: After prolonged use, brake pads become thinner due to constant friction. Overly thin brake pads not only reduce braking effectiveness but also harden, causing abnormal noises. 5. Rusty brake discs: Long-term exposure to weather can cause brake discs to rust.
