Fras-le, a leading CV brake supplier, has outlined essential maintenance practices to address common brake drum issues such as heat checks, martensite spotting, and blued surfaces. Proper attention to these issues can significantly extend the longevity of brake drums and enhance vehicle safety.
Key Highlights:
- Heat Checking: Appears as fine cracks caused by repeated heating and cooling. Replace the brake drum if cracks enlarge.
- Martensite Spotting: Identified as dark, raised spots from excessive heat exposure. Replace both the drum and linings while addressing the overheating cause.
- Blued Drums: Result from frequent hard stops or imbalances. Inspect for system faults to prevent serious damage.
- Broken Mounting Rings: Caused by improper installation or hub defects. Clean, repair, or replace affected components promptly.
Fras-le emphasizes the importance of regular inspections and timely interventions to prevent minor issues from escalating into costly repairs.
