Introduction to Motorcycle Brake Shoes Brass-Free Mixture
Brass-free brake shoes mixture represents an eco-conscious innovation in motorcycle friction technology, designed to replace traditional brass-reinforced formulations while maintaining high braking efficiency and compliance with global environmental regulations. These brake shoes friction materials utilize steel fibers, ceramic particles, and synthetic binders to achieve superior performance without heavy metal content. Below is a detailed overview of their technical specifications, advantages, and storage guidelines.
Technical Parameters
The table below outlines the key properties of brass-free brake shoes mixes:
| Parameter | Specification | Remarks |
|---|---|---|
| Steel Fiber Content | 30-45% (Low-carbon steel fibers) | Enhances structural integrity and heat dissipation |
| Density | 2.2-2.8 g/cm³ | Optimized for lightweight durability |
| Friction Coefficient (μ) | 0.38-0.48 (Dry) | Stable under high-speed braking conditions |
| Operating Temperature | -30°C to 550°C | Reduces thermal fade by 25% vs. brass-based formulas |
| Compressive Strength | ≥280 MPa | Suitable for aggressive motorcycle braking |
| Wear Rate | ≤0.4 cm³/MJ | Extends service life by 30% |
| Shore Hardness | 65-80 Shore D | Ensures compatibility with drum surfaces |
Key Advantages
- Eco-Friendly Composition
The brake shoes formula eliminates brass, aligning with RoHS and REACH regulations to minimize environmental impact. - Reduced Dust Emission
Synthetic binders and ceramic additives in the brake shoes friction materials reduce brake dust by 40%, improving rider safety and cleanliness. - Enhanced Heat Resistance
Steel fibers and ceramic particles dissipate heat efficiently, preventing brake fade during downhill or high-load braking. - Low Noise
Vibration-damping additives eliminate high-frequency squeal, enhancing rider comfort. - Universal Compatibility
Designed for seamless integration with both drum and composite brake systems in motorcycles.
Storage and Packaging
- Moisture Control: Packaged in vacuum-sealed, anti-oxidation bags to prevent steel fiber corrosion.
- Temperature: Store in dry conditions between 5°C–35°C to maintain adhesive properties.
- Stacking: Maximum 6 layers to avoid deformation of friction layers.
- Shelf Life: 18 months in unopened, UV-resistant packaging.
Application of Brake Shoes Mixes
The brake shoes mixes are molded under high pressure (18–25 MPa) and cured at 150°C–200°C to bond the friction layer to the shoe plate. Post-production quality tests include thermal cycling (300 cycles at 550°C) and shear strength validation (≥3.5 MPa). Customizable formulations are available for OEMs requiring specific friction profiles or compliance with regional standards.
By combining advanced materials with sustainable design, brass-free brake shoes friction materials deliver reliable braking performance while addressing environmental and regulatory challenges in the motorcycle industry.
