Introduction to Motorcycle Brake Shoes Non-Asbestos Mixture
Motorcycle brake shoes non-asbestos mixtures are environmentally friendly brake shoes friction materials designed to replace traditional asbestos-based formulations. These brake shoes mixes utilize advanced mineral fibers, ceramic particles, and organic binders to ensure safe, reliable, and durable braking performance. Below is a detailed overview of their composition, technical specifications, advantages, and storage guidelines.
Technical Parameters
The table below highlights the key properties of non-asbestos brake shoes mixture:
| Parameter | Specification | Remarks |
|---|---|---|
| Non-Asbestos Content | 60-80% (Mineral fibers, ceramic) | Complies with global safety standards |
| Density | 2.0-2.5 g/cm³ | Lightweight yet robust |
| Friction Coefficient (μ) | 0.30-0.40 (Dry) | Balanced for urban and off-road use |
| Operating Temperature | -30°C to 450°C | Resists thermal degradation |
| Compressive Strength | ≥200 MPa | Suitable for high-stress braking |
| Wear Rate | ≤0.4 cm³/MJ | 30% lower than asbestos alternatives |
| Shore Hardness | 55-70 Shore D | Optimized for drum surface contact |
Key Advantages
- Eco-Friendly Composition
The brake shoes formula eliminates asbestos, reducing health risks and aligning with EU/EPA regulations. - Thermal Stability
Ceramic additives enhance heat dissipation, preventing brake fade during frequent stops. - Low Noise and Vibration
Organic binders and layered fibers minimize squeal, ensuring quiet operation. - Extended Lifespan
A wear rate of ≤0.4 cm³/MJ makes these brake shoes friction materials ideal for high-mileage motorcycles. - Compatibility
Designed for seamless integration with cast iron or alloy brake drums.
Storage and Packaging
- Moisture Protection: Packaged in vacuum-sealed, anti-humidity bags to prevent fiber swelling.
- Temperature: Store in dry conditions between 10°C–35°C to maintain adhesive integrity.
- Stacking: Limit to 6 layers to avoid deformation of friction surfaces.
- Shelf Life: 24 months in unopened, factory-sealed containers.
Application of Brake Shoes Mixes
The brake shoes mixes are molded under 10–20 MPa pressure and cured at 150°C–200°C to bond the friction layer to steel backing plates. Post-production tests include thermal cycling (300 cycles at 450°C) and shear strength validation (≥3.0 MPa). Customized formulations are available for OEMs requiring specific friction profiles or regional regulatory compliance.
By combining sustainability with high-performance engineering, non-asbestos brake shoes mixtures redefine safety and reliability for motorcycles in diverse riding conditions.
