What causes a clacking rattling noise when braking or accelerating from stop?

A clacking or rattling noise when braking or accelerating from a stop can be caused by several issues. Common culprits include loose or worn brake components, such as calipers or pads, which may produce noise when they shift under pressure. Additionally, worn suspension parts, like bushings or struts, can create similar sounds due to increased movement during acceleration or braking. Lastly, issues with the drivetrain, such as a failing CV joint, may also contribute to this noise.
