Cadillac XTS brakes squeaking when reversing despite dealer assurance on Cadillac XTS

Some Cadillac XTS owners report experiencing persistent squeaking brakes, particularly when reversing, despite assurances from dealers that the issue has been resolved. Common causes of this problem include worn-out brake pads, which have a built-in squealer that emits a high-pitched sound when they are depleted, and a lack of lubrication, especially noticeable during morning use. Additionally, improper installation of brake components can contribute to the squeaking noise. To address these issues, some owners have found success by applying anti-squeal lubricant, adjusting brake hardware, or using noise-reducing shims. Professional inspections of pad thickness, rotors, calipers, and fluid levels are also recommended to identify underlying issues. In some cases, replacing rear disc brake pads with a new design may be necessary to eliminate the squeal. This ongoing concern underscores the importance of thorough diagnosis and maintenance to effectively resolve brake squeaking in the Cadillac XTS.
