How To Choose The Material For Brake Linings?
Understanding Common Drum Brake Pad Material Types
Currently, drum brake pads on the market are mainly made of the following materials:
Composition: Contains approximately 30% - 65% metal (mainly steel or copper) fibers, mixed with other fillers.
Characteristics:
Advantages: Good braking performance, high temperature resistance, fast heat dissipation, and low price.
Disadvantages: Wears the brake drum (pairing parts) relatively quickly, may be noisier, and braking performance is slightly worse at low temperatures.
Suitable Scenarios: Heavy-duty, frequent braking, or cost-sensitive economy vehicles. For example, small trucks, pickup trucks, or some older economy cars.
Composition: Lower metal content (approximately 10% - 30%), filled with other organic materials.
Features:
Advantages: Smoother and smoother braking performance than semi-metallic brakes; relatively less noise and dust; less wear on brake drums.
Disadvantages: Less heat-resistant than semi-metallic brakes; may generate more heat in extreme conditions.
Suitable Scenarios: Most modern family cars, standard factory option. Balances performance, comfort, and cost.
Composition: Metal-free, primarily composed of a blend of organic materials such as glass fiber, rubber, carbon, and Kevlar.
Features:
Advantages: Very quiet, smooth braking, minimal wear on brake drums.
Disadvantages: Poor wear resistance, shorter lifespan, produces more brake dust, prone to brake fade (reduced braking performance) at high temperatures.
Suitable Scenarios: Daily urban commuting, gentle driving, suitable for noise-sensitive drivers. Not suitable for aggressive driving or heavy loads.
Composition: Contains ceramic fibers, fillers, and a small amount of copper wire.
Features:
Advantages: Extremely quiet, produces almost no visible dust, stable braking performance, excellent heat fade resistance, and minimal wear on the brake drum.
Disadvantages: Most expensive, requires preheating to achieve optimal braking performance at low temperatures.
Suitable Scenarios: High-end sedans seeking ultimate comfort, quietness, and cleanliness; car owners who require minimal performance degradation; those with a sufficient budget.
Make Your Choice Based on Your Specific Circumstances (Decision Guide)
Please consider the following questions in order:
What is your driving style and primary road conditions?
Mild driving, city commuting: Low-metallic or organic pads are excellent choices. They are quiet, smooth, and perfectly suited for daily use.
Intense driving, frequent mountain/highway driving: Better heat resistance and braking performance are required. Semi-metallic or high-performance low-metallic pads are more suitable.
Heavy load/towing: If you drive a pickup truck, van, or frequently haul heavy loads, semi-metallic pads are the preferred choice due to their strong braking power and high-temperature resistance.
What is your budget?
Economy First: Semi-metallic liners are the cheapest, but you must accept the potential noise and wear on the brake drums.
Balanced Performance: Low-metallic liners are the mainstream choice, moderately priced, and offer balanced performance, making them the preferred option for most people.
Unscrupulous in Pursuit of Optimal Comfort: Go straight for ceramic liners. Although more expensive, they provide the quietest and cleanest driving experience.
How Tolerant Are You of Noise and Dust?
Extremely Sensitive to Noise: Avoid semi-metallic liners; ceramic is the first choice, followed by organic and low-metallic.
Want Clean Wheels: Ceramic liners produce almost no black dust, while organic liners produce the most.
What is your vehicle type and original factory configuration?
Check your owner's manual or the original brake lining: If the original brake lining are low-metallic, it's best to replace them with the same type or a higher grade (e.g., upgrade to ceramic). Do not downgrade from ceramic/low-metallic to semi-metallic, as this may affect brake balance and ABS system operation.
Small economy cars: Low-metallic or organic.
Performance cars/luxury cars: It is recommended to use original factory specified or equivalent high-performance low-metallic/ceramic brake linings.
