Key Advantages
- Optimized Braking Performance
- The low metallic Brake Shoes Mixes incorporate steel fibers and graphite, ensuring stable friction coefficients across wet/dry conditions.
- Noise reduction: ≤72 dB at 80 km/h braking tests.
- Extended Service Life
- Reinforced brake shoes friction materials (aramid pulp + ceramic particles) reduce wear rates by 25% compared to conventional metallic formulas.
- Eco-Friendly Design
- 30% lower copper content than standard metallic shoes, complying with U.S. Copper-Free Brake Initiative (CFBI) regulations.
- Thermal Management
- Heat dissipation grooves in the lining structure prevent thermal fade at sustained 400°C+ temperatures.
Formula Composition
The brake shoes formula consists of:
- Friction Modifiers: Graphite (10–12%), cashew particles (8–10%)
- Metallic Components: Steel wool (10–12%), copper flakes (3–5%)
- Binders: Phenolic resin (15–18%)
- Reinforcements: Aramid fibers (5–7%), baryte powder (20–25%)
Packaging & Storage Guidelines
- Packaging:
- Individually wrapped in anti-corrosion VCI paper.
- Stacked on wooden pallets with moisture-proof film (max 5 layers).
- Storage:
- Temperature: 5°C–35°C in low-humidity environments (<65% RH).
- Avoid direct sunlight and chemical exposure.
This low metallic brake shoes mixture achieves optimal balance between braking efficiency, rotor compatibility, and environmental compliance, making it a sustainable choice for modern automotive systems.
