Introduction to Car Brake Shoes with Brass-Free Mixture
Brass-free brake shoes mixture is an innovative advancement in brake shoes friction materials, engineered to meet stringent environmental regulations while ensuring high-performance braking for passenger and commercial vehicles. This brake shoes formula eliminates brass and other heavy metals, utilizing eco-friendly alternatives like ceramic fibers, aramid composites, and organic binders to deliver reliable friction performance and reduced environmental impact. Below is a detailed technical overview, advantages, and storage guidelines for this advanced friction material.
Technical Parameters of Brass-Free Brake Shoes Mixture
| Parameter | Specification |
|---|---|
| Friction Coefficient (μ) | 0.38–0.48 (stable at 0–500°C) |
| Operating Temperature | -30°C to 500°C |
| Density | 2.2–2.6 g/cm³ |
| Thickness | 6–15 mm (customizable) |
| Shear Strength | ≥3.5 MPa |
| Noise Level | ≤65 dB (low-noise design) |
Note: Parameters vary based on formulations for specific vehicle models (e.g., Toyota, Ford, Volkswagen).
Key Advantages of Brass-Free Brake Shoes
- Environmental Compliance
- Free from brass, copper, and asbestos, aligning with global regulations (e.g., RoHS, REACH).
- Reduced heavy metal contamination in brake dust, protecting ecosystems.
- Enhanced Durability
- Brake shoes friction materials maintain stable friction performance under high-temperature conditions, minimizing brake fade during frequent stops.
- Low abrasiveness extends the lifespan of brake drums and reduces maintenance costs.
- Superior Comfort
- Optimized brake shoes mixes incorporate damping layers to reduce vibration and noise (<65 dB), ensuring a quieter driving experience.
- Thermal Stability
- Ceramic-reinforced brake shoes formula resists thermal degradation, even in urban stop-and-go traffic.
- Versatility
- Compatible with drum brake systems in sedans, SUVs, and light trucks (e.g., Honda Civic, Ford Transit).
Packaging and Storage Guidelines
- Packaging:
- Vacuum-sealed moisture-resistant bags + reinforced cardboard boxes to prevent deformation during transit.
- Labels include OEM codes (e.g., TRW GDB1742, Bosch 0986487953) and certifications (IATF16949, ISO 9001).
- Storage:
- Temperature: 10–35°C; Humidity: ≤50%.
- Avoid stacking over 5 layers and exposure to corrosive substances.
Applications
The brake shoes mixture is ideal for:
- Passenger vehicles with drum brake systems (e.g., Toyota Corolla, Hyundai Elantra).
- Light commercial vehicles requiring eco-friendly and low-dust solutions.
