Hard spots on a brake drum can be caused by uneven heating during braking, often due to excessive brake use or a malfunctioning braking system. This can lead to localized hardening of the drum material, resulting in inconsistent surface texture. Additionally, contamination from oil or grease can contribute to hard spots, as can manufacturing defects or wear over time. Regular inspections and maintenance can help prevent these issues.
