Introduction to Motorcycle Brake Shoes Metallic Mixture
Motorcycle brake shoes metallic mixtures are high-performance brake shoes friction materials designed to deliver reliable stopping power for two-wheelers under diverse riding conditions. These brake shoes mixes blend metallic components (iron, copper, steel fibers) with organic binders and friction modifiers, ensuring optimal heat dissipation, wear resistance, and consistent braking performance. Below is a detailed overview of their technical specifications, advantages, and storage guidelines.
Technical Parameters
The table below summarizes key properties of a metallic-based brake shoes formula:
| Parameter | Specification | Remarks |
|---|---|---|
| Metallic Content | 45-60% (Iron, Copper, Steel fibers) | Enhances thermal conductivity and durability |
| Density | 2.4-2.8 g/cm³ | Balances lightweight and structural integrity |
| Friction Coefficient (μ) | 0.35-0.45 (Dry) | Stable across urban and high-speed braking |
| Operating Temperature | -40°C to 550°C | Resists fade during frequent stops |
| Compressive Strength | ≥220 MPa | Withstands hydraulic pressure in drum brakes |
| Wear Rate | ≤0.4 cm³/MJ | 30% lower than organic counterparts |
| Shore Hardness | 55-70 Shore D | Optimized for motorcycle drum contact |
Key Advantages
- Enhanced Heat Resistance
Metallic components in the brake shoes mixture efficiently dissipate heat, reducing thermal fade during aggressive riding or downhill braking. - Long Service Life
Reinforced with steel fibers, the brake shoes friction materials exhibit minimal wear, ideal for high-mileage motorcycles. - Consistent Braking
The brake shoes formula maintains stable friction coefficients across wet and dry conditions, ensuring rider safety. - Noise Reduction
Graphite additives minimize vibration and squeal, enhancing ride comfort. - Cost-Effectiveness
Durable design reduces replacement frequency, lowering long-term maintenance costs.
Storage and Packaging
- Moisture Protection: Packaged in vacuum-sealed, anti-corrosion bags to prevent oxidation of metallic elements.
- Temperature Range: Store at 0°C–35°C; avoid prolonged exposure to humidity or direct sunlight.
- Stacking: Limit to 4 layers to prevent deformation of friction surfaces.
- Shelf Life: 18 months in unopened, factory-sealed containers.
Application of Brake Shoes Mixes
The brake shoes mixes are precision-molded under 10–20 MPa pressure and cured to bond the friction layer to the shoe plate. Post-production testing includes shear strength validation (≥3.5 MPa) and thermal cycling tests (300 cycles at 550°C) to ensure compliance with OEM standards. Custom formulations are available for racing or touring motorcycles requiring specific friction profiles.
By integrating robust metallic matrices with advanced engineering, these brake shoes friction materials provide dependable braking performance for motorcycles in both urban and off-road environments.
