Advantages of Semi-Metallic Brake Pads
- Superior Heat Management
- High metallic content in the Brake Pads Mixes improves thermal conductivity, reducing brake fade during prolonged downhill braking.
- Extended Service Life
- Steel fibers enhance wear resistance, achieving 40,000–60,000 km lifespan under typical truck loads.
- Cost-Effective Performance
- Optimized brake pads formula balances copper-free requirements (per US EPA regulations) and friction stability, reducing total ownership costs by 15–20%.
- Adaptability to Harsh Conditions
- Maintains friction consistency in wet, muddy, or high-salinity environments, ideal for mining and long-haul trucks.
Storage & Packaging Guidelines
- Packaging:
- Individually wrapped in anti-rust VCI (Volatile Corrosion Inhibitor) paper.
- Stacked in reinforced wooden crates with shock-absorbent spacers.
- Storage:
- Temperature: -10°C–35°C in dry environments (max humidity 50% RH).
- Avoid direct sunlight exposure; maximum stacking height: 8 layers.
Key Formula Components
The brake pads mixture includes:
- Metallic Elements: Steel wool (25–35%), iron oxide (10–15%)
- Friction Modifiers: Graphite (8–12%), cashew dust (5–8%)
- Binders: Phenolic resin (12–15%) with hexamine curing agent
This brake pads formula is engineered for trucks requiring high torque braking capacity and compliance with global environmental regulations.
