Introduction to Car Brake Shoes with Copper-Free Mixture
Copper-free brake shoes mixture is a modern innovation in brake shoes friction materials, designed to address environmental concerns while maintaining high-performance braking for passenger vehicles. This brake shoes formula eliminates copper and other heavy metals, replacing them with ceramic compounds, aramid fibers, and synthetic binders to ensure compliance with global eco-regulations (e.g., REACH, California SB 346). Below is a technical overview, advantages, and storage guidelines for this sustainable friction material.
Technical Parameters of Copper-Free brake shoes mixes
| Parameter | Specification |
|---|---|
| Friction Coefficient (μ) | 0.38–0.48 (stable at 0–500°C) |
| Operating Temperature | -30°C to 550°C |
| Density | 2.2–2.6 g/cm³ |
| Thickness | 6–15 mm (customizable) |
| Shear Strength | ≥3.5 MPa |
| Noise Level | ≤65 dB (low-noise optimized) |
Note: Adjustable for specific car models (e.g., Ford, Mazda, Toyota).
Advantages of Copper-Free Brake Shoes Mixture
- Environmental Sustainability
- Copper-free brake shoes formula eliminates toxic heavy metals, reducing water and soil contamination.
- Complies with strict regulations like EU Directive 2000/53/EC and U.S. SB 346.
- Enhanced Durability
- Ceramic-based brake shoes friction materials resist thermal fade, ensuring consistent braking even during high-speed stops.
- Low wear rate extends rotor lifespan by up to 30% compared to traditional semi-metallic mixes.
- Superior Comfort
- Optimized brake shoes mixes reduce noise and vibration through layered damping structures.
- Minimal dust generation preserves wheel aesthetics.
- Broad Compatibility
- Suitable for sedans, SUVs, and hybrid vehicles (e.g., Ford Ranger, Mazda B-Series).
Packaging and Storage Guidelines
- Packaging:
- Vacuum-sealed, moisture-resistant bags + reinforced cartons for bulk transport.
- Labels include part numbers (e.g., WVA29087, FMSI D1074) and certifications (IATF16949, ISO 9001).
- Storage:
- Temperature: 10–35°C; Humidity: ≤55%.
- Avoid stacking above 1.5 meters to prevent deformation.
Applications
This brake shoes mixture is ideal for:
- Passenger cars requiring eco-compliant braking systems.
- Urban vehicles prioritizing low noise and dust emissions.
