What Causes the Abnormal Noise When Braking in a BMW?
1 Answers
BMW braking abnormal noise causes are as follows: Brake pad quality: Substandard brake pads will produce abnormal noises during braking while also damaging the brake discs. It's necessary to replace them with genuine brake pads at an authorized 4S dealership. Foreign objects in brake discs: When driving on complex road conditions, wheels can easily fling up stones or other debris. Rocks lodged between brake pads and discs create abnormal noises during braking, requiring prompt removal of the obstruction. Severely worn brake discs: Friction between brake pads and heavily worn discs will likewise generate abnormal noises, necessitating immediate brake disc replacement. Excessively worn brake pads: After prolonged vehicle use, continuous friction gradually thins the brake pads. Overly thin pads not only reduce braking efficiency but also harden the material, causing abnormal noises during braking. Timely replacement of brake pads resolves this issue.
