Introduction to Motorcycle Brake Shoes Metallic-Based Mixture
Motorcycle brake shoes metallic-based mixtures are high-performance brake shoes friction materials designed for superior stopping power and durability in demanding riding conditions. These brake shoes mixes blend metallic components (e.g., iron, copper, steel fibers) with advanced binders and additives to optimize friction stability, heat dissipation, and wear resistance. Below is a detailed overview of their technical specifications, advantages, and storage guidelines.
Technical Parameters
The table below summarizes key properties of a typical metallic-based brake shoes formula:
| Parameter | Specification | Remarks |
|---|---|---|
| Metallic Content | 45-65% (Iron, Steel Fibers, Copper) | Enhances thermal conductivity and structural integrity |
| Density | 2.5-3.0 g/cm³ | Balances lightweight and strength |
| Friction Coefficient (μ) | 0.35-0.45 (Dry) | Consistent performance across speeds |
| Operating Temperature | -30°C to 550°C | Resists brake fade during aggressive use |
| Compressive Strength | ≥280 MPa | Withstands high-pressure braking |
| Wear Rate | ≤0.4 cm³/MJ | 30% lower than organic alternatives |
| Shore Hardness | 55-70 Shore D | Optimized for drum contact and noise control |
Key Advantages
- Enhanced Heat Resistance
Metallic components like iron and steel fibers rapidly dissipate heat, reducing thermal fade during repeated braking. - Extended Service Life
The brake shoes mixture exhibits a wear rate of ≤0.4 cm³/MJ, ideal for high-mileage motorcycles. - Stable Friction Performance
Engineered for consistent friction coefficients, even in wet or dusty conditions, ensuring rider safety. - Noise Reduction
Additives like graphite minimize vibration and squeal, common in organic friction materials. - Compatibility
Designed to work seamlessly with cast iron or alloy brake drums, widely used in motorcycles.
Storage and Packaging
- Moisture Control: Packaged in vacuum-sealed, anti-corrosion bags to prevent oxidation of metallic components.
- Temperature: Store in dry environments (15°C–35°C) to preserve adhesive properties in the brake shoes formula.
- Stacking: Limit to 4 layers to avoid deformation of friction linings.
- Shelf Life: 18 months in unopened, factory-sealed containers.
Application of Brake Shoes Mixes
The brake shoes mixes are molded under high pressure (10–25 MPa) and cured to bond the friction layer to steel backing plates. Post-production testing includes shear strength validation (≥3.5 MPa) and thermal cycling to ensure reliability under extreme conditions. Custom formulations are available for racing or heavy-load motorcycles requiring tailored friction profiles.
Combining robust engineering with advanced materials, metallic-based brake shoes friction materials deliver unmatched performance for motorcycles navigating urban streets or rugged terrains.
