Key Advantages
- Ultra-High Thermal Resistance
The brake shoes friction materials leverage silicon carbide’s refractory properties, maintaining stable performance even during prolonged downhill braking or track use. - Lightweight Design
With a density of 1.6-2.0 g/cm³, the brake shoes mixes reduce rotational inertia, improving motorcycle acceleration and handling. - Low Dust and Noise
Ceramic additives in the brake shoes formula minimize dust emissions and eliminate high-frequency squeal, complying with environmental regulations. - Corrosion Resistance
Carbon-ceramic matrices resist oxidation and moisture degradation, ideal for off-road or humid environments. - Extended Service Life
A wear rate of ≤0.2 cm³/MJ ensures compatibility with long-distance touring or racing cycles (15,000–50,000 km).
Storage and Packaging
- Moisture Control: Vacuum-sealed in anti-corrosion aluminum foil bags to prevent ceramic matrix hydrolysis.
- Temperature Limits: Store at 10°C–35°C; avoid freezing to prevent adhesive layer brittleness.
- Stacking: Maximum 3 layers to avoid deformation of friction surfaces.
- Shelf Life: 18 months in unopened, UV-resistant packaging.
Application of Brake Shoes Mixes
The brake shoes mixes are precision-molded under 25–40 MPa pressure and sintered at 1,200°C to bond the carbon-ceramic layer to aluminum or steel backplates. Post-production testing includes thermal shock cycles (800°C to room temperature) and shear strength validation (≥4.0 MPa). Customized formulations are available for OEMs requiring specific friction profiles or compatibility with composite brake systems.
By integrating carbon-ceramic technology with advanced engineering, these brake shoes friction materials redefine safety and performance for motorcycles in both urban and extreme riding conditions.
