Introduction to Motorcycle Brake Shoes No-Copper Mixture
Motorcycle brake shoes no-copper mixtures are environmentally optimized brake shoes friction materials designed to meet stringent global regulations on copper reduction while maintaining high braking efficiency. These brake shoes mixes replace traditional copper components with ceramic fibers, mineral reinforcements, and steel alloys, ensuring compliance with ecological standards without compromising performance. Below is a detailed breakdown of their composition, technical specifications, advantages, and storage protocols.
Technical Parameters
The table below summarizes the critical properties of no-copper brake shoes formula:
Parameter | Specification | Remarks |
---|---|---|
Copper-Free Composition | 0% Copper; 30-45% Ceramic/Mineral Fibers | Complies with EPA/REACH regulations |
Density | 2.0-2.5 g/cm³ | Lightweight yet durable |
Friction Coefficient (μ) | 0.38-0.48 (Dry) | Stable across wet and dry conditions |
Operating Temperature | -30°C to 550°C | Resists thermal degradation |
Compressive Strength | ≥280 MPa | Suitable for high-stress braking |
Wear Rate | ≤0.4 cm³/MJ | 25% lower than copper-based mixes |
Shear Strength | ≥3.5 MPa | Ensures bonding integrity |
Key Advantages
- Eco-Friendly Compliance
The brake shoes mixture eliminates copper, reducing environmental contamination and aligning with global bans (e.g., Washington State’s 2025 copper-free mandate). - Enhanced Heat Resistance
Ceramic fibers and mineral additives dissipate heat efficiently, preventing brake fade during aggressive riding. - Low Dust Emission
Non-metallic components minimize dust generation, reducing wheel rim contamination. - Noise Reduction
Optimized brake shoes friction materials incorporate vibration-dampening agents (e.g., rubberized graphite), eliminating squeal. - Extended Service Life
A wear rate of ≤0.4 cm³/MJ ensures longevity, ideal for urban commuting and touring motorcycles.
Storage and Packaging
- Moisture Protection: Vacuum-sealed in anti-corrosion aluminum foil bags to prevent fiber degradation.
- Temperature Control: Store at 5°C–35°C; avoid humidity above 60%.
- Stacking: Maximum 6 layers to avoid deformation of friction linings.
- Shelf Life: 18 months in unopened packaging; use within 3 months after opening.
Application of Brake Shoes Mixes
The brake shoes mixes are precision-molded under 15–25 MPa pressure and cured at 150°C–200°C to bond friction layers to steel backing plates. Post-production tests include thermal shock cycles (300 cycles at 550°C) and shear strength validation. Customizable formulations cater to OEM requirements for sport bikes, cruisers, or off-road motorcycles.
By integrating eco-conscious materials with advanced engineering, no-copper brake shoes friction materials deliver reliable braking performance while supporting global sustainability goals. For bulk specifications or technical datasheets, refer to certified suppliers like TBT or Alibaba listings.
