Introduction to Motorcycle Brake Shoes HD (High-Density) Metallic Mixture
Motorcycle brake shoes HD metallic mixtures are high-performance brake shoes friction materials engineered for aggressive braking scenarios, combining metallic reinforcements with advanced binders to achieve exceptional durability, heat resistance, and consistent friction output. Designed for high-speed motorcycles and off-road applications, this brake shoes formula optimizes stopping power while minimizing wear. Below is a detailed breakdown of its technical specifications, advantages, and storage protocols.
Technical Parameters
The table below highlights key properties of the HD metallic brake shoes mixture:
| Parameter | Specification | Remarks |
|---|---|---|
| Metallic Content | 60-75% (Iron, Steel, Copper fibers) | Enhances thermal conductivity and structural rigidity |
| Density | 3.0-3.5 g/cm³ | High-density design for reduced material fatigue |
| Friction Coefficient (μ) | 0.38-0.48 (Dry) | Stable under rapid deceleration cycles |
| Operating Temperature | -30°C to 650°C | Resists glazing and fade at extreme temps |
| Compressive Strength | ≥320 MPa | Withstands high-pressure braking forces |
| Wear Rate | ≤0.4 cm³/MJ | 25% lower than standard metallic mixes |
| Shore Hardness | 65-80 Shore D | Balances grip and drum compatibility |
Key Advantages
- Enhanced Durability
The brake shoes mixes incorporate steel and copper fibers, reducing wear rates by 25% compared to conventional materials, ideal for frequent stop-and-go riding. - Superior Heat Dissipation
High metallic content ensures rapid heat transfer, preventing brake fade during prolonged downhill or track use. - Consistent Braking Response
Optimized brake shoes friction materials maintain a stable μ-value across wet and dry conditions, critical for safety in variable terrains. - Noise and Vibration Control
Graphite additives in the brake shoes formula dampen high-frequency vibrations, eliminating squeal common in metal-heavy designs. - Eco-Compatibility
Asbestos-free composition aligns with global environmental standards, reducing hazardous dust emissions.
Storage and Packaging
- Moisture Protection: Vacuum-sealed, anti-corrosion packaging to prevent oxidation of metallic components.
- Temperature Range: Store at 0°C–35°C; avoid humidity above 60% to preserve adhesive integrity.
- Stacking Limits: Maximum 5 layers to prevent deformation of friction layers.
- Shelf Life: 18 months in unopened, factory-sealed containers.
Application of Brake Shoes Mixes
The brake shoes mixes are molded under high pressure (18–30 MPa) and cured at 150°C–200°C to bond the metallic matrix to stamped steel or aluminum backing plates. Post-production quality tests include thermal shock resistance (500 cycles at 650°C) and shear strength validation (≥4.0 MPa). Custom formulations are available for OEMs requiring tailored friction profiles or compatibility with ABS systems.
By integrating high-density metallic engineering with precision manufacturing, these brake shoes friction materials deliver unmatched reliability for motorcycles operating in demanding environments, from urban commuting to competitive racing.
