How can Drum Brake Linings effectively prevent excessive wear and tear?

Excessive wear of drum brake linings is a common and important issue in automotive braking systems, which directly affects the performance and safety of braking. To effectively prevent excessive wear of drum brake pads, the following aspects can be taken into consideration:

Reasonable driving habits
Smooth braking: During driving, try to avoid sudden and emergency braking, and smoothly press and release the brake pedal to reduce friction and wear between the brake pads and brake drums.
Proactive driving: Observe the road conditions in advance, slow down or stop in advance, and avoid the need for strong braking in emergency situations, thereby reducing the burden on the braking system.
Regular maintenance and inspection
Brake system inspection: Regularly inspect the brake system, including the thickness of brake pads, wear of brake drums, quality and quantity of brake fluid, etc. Once severe wear of the brake lining or uneven surface of the brake drum is found, it should be replaced or repaired in a timely manner.
Brake adjustment: Ensure that the brake system is adjusted correctly, the gap between the brake pads and the brake drum is appropriate, and avoid abnormal wear caused by too tight or too loose.

Maintenance and repair of brake drum
Cleaning of brake drum: Regularly clean the surface of the brake drum to remove impurities such as oil and dust, maintain the cleanliness and smoothness of the brake drum surface, and reduce friction and wear during braking.
Grinding of brake drum: For slight wear or unevenness, the surface of the brake drum can be polished with professional grinding tools to restore its flatness and smoothness, thereby extending the service life of the brake lining.
Brake drum replacement: When the brake drum is severely worn and cannot be repaired by grinding, a new brake drum should be replaced in a timely manner to ensure the performance and safety of the brake system.
Use high-quality brake pads
Choose high-quality brake pads: When purchasing brake pads, you should choose products with reliable quality and stable performance. High quality brake pads have better wear resistance, heat resistance, and braking performance, which can reduce wear and extend service life.
Adaptability check: Ensure that the selected brake pads are compatible with the vehicle's braking system, including dimensions, shape, and materials. Inappropriate brake pads may cause abnormal wear or reduced braking performance.
Pay attention to the heat dissipation of the brake system
Avoid prolonged continuous braking: In situations of long downhill or continuous braking, attention should be paid to the heat dissipation of the braking system. Long term continuous braking can cause the brake system to overheat, accelerate the wear of brake pads and brake drums. Therefore, when continuous braking is required, the vehicle speed should be appropriately reduced, and the number and duration of braking should be minimized.
Using heat dissipation auxiliary devices: For high-performance vehicles or vehicles that often need to drive in harsh road conditions, it is recommended to install brake heat dissipation auxiliary devices, such as brake ventilation discs, heat sinks, etc., to improve the heat dissipation performance of the brake system.
Other precautions
Avoid overloading: Overloading the vehicle will increase the burden on the brake system, accelerate the wear of brake pads and brake drums. Therefore, loading should be strictly carried out according to the load limit specified by the vehicle.
Regularly replace brake fluid: Brake fluid is an important component of the brake system, which transmits pressure from the brake pedal to the brake pads. Regularly replacing brake fluid can maintain its stable performance and reduce the wear and failure of the brake system.

Through reasonable driving habits, regular maintenance and inspection, maintenance and repair of brake drums, use of high-quality brake pads, attention to heat dissipation of the brake system, and other precautions, efforts can be made to effectively prevent excessive wear of drum brake pads, ensuring the performance and safety of the brake system.
