Common Brake Drum Problems and Their Effects
1. After prolonged use, uneven wear may appear on the surface of the brake drum, which can cause noise and vibration during braking, and in severe cases, affect braking performance.
2. Frequent hard braking or prolonged downhill driving can cause the brake drum to deform due to high temperatures, affecting the contact between the brake pads and the drum surface, and reducing braking efficiency.
3. Damp environments or lack of maintenance can cause rust on the surface of the brake drum. Dust, oil, and other impurities may also adhere to it, reducing friction and affecting braking performance.
4. In extreme cases, such as severe impacts or material defects, cracks or even damage may occur in the brake drum. This is an extremely dangerous fault and must be replaced immediately.
Brake Drum Maintenance Methods
1. It is recommended to conduct a comprehensive inspection of the braking system every 10,000 to 20,000 kilometers or as required by the vehicle's owner's manual, including checking the wear of the brake drum, whether the surface is smooth, and whether there are any cracks.
2. Use a dedicated brake cleaner to remove oil, dust, and rust from the surface of the brake drum. Be careful not to use cleaners containing abrasive particles, as this may scratch the drum surface. After cleaning, a thin layer of rust preventive oil can be applied to extend its service life.
3. After prolonged high-speed driving or frequent braking, allow the vehicle to cool naturally. Avoid immediately washing the braking system with cold water to prevent thermal expansion and contraction from causing component deformation.
4. The gap between the brake pads and the brake drum should be kept within a reasonable range. If it is too tight, it will increase wear, and if it is too loose, it will affect the braking response speed. Regularly adjust it at a professional repair shop to ensure stable braking performance.
