Introduction to Motorcycle Brake Shoes High Metallic Mixture
Motorcycle brake shoes high metallic mixtures are engineered brake shoes friction materials designed for aggressive braking performance in high-speed and high-temperature scenarios. This brake shoes formula integrates a high proportion of metallic components (e.g., steel fibers, copper alloys) with binding resins and friction modifiers, optimizing durability, heat dissipation, and consistent stopping power. Below is a detailed breakdown of its technical specifications, advantages, and storage protocols.
Technical Parameters
The table below highlights key properties of high-metallic brake shoes mixes:
| Parameter | Specification | Remarks |
|---|---|---|
| Metallic Content | 40-60% (Steel fibers, copper alloys) | Improves thermal conductivity |
| Density | 2.8-3.5 g/cm³ | Balances lightweight and wear resistance |
| Friction Coefficient (μ) | 0.38-0.45 (Dry) | Stable under repeated braking |
| Operating Temperature | -30°C to 550°C | Minimizes thermal fade |
| Compressive Strength | ≥280 MPa | Resists deformation under stress |
| Wear Rate | ≤0.6 cm³/MJ | Extends service life |
| Shore Hardness | 65-80 Shore D | Ensures firm drum contact |
Key Advantages
- Superior Heat Dissipation
The high metallic brake shoes mixture efficiently transfers heat away from the friction surface, reducing brake fade during prolonged use. - Enhanced Durability
Reinforced with steel fibers, these brake shoes friction materials withstand abrasive wear, making them ideal for high-mileage motorcycles and off-road ATVs. - Consistent Braking Performance
The optimized brake shoes formula maintains a stable friction coefficient across varying speeds and road conditions. - Noise Reduction
Graphite or ceramic additives minimize vibration and squeal, ensuring quieter operation. - Versatility
Compatible with both drum and composite brake systems, suitable for street bikes, racing motorcycles, and ATVs.
Storage and Packaging
- Moisture Protection: Packed in vacuum-sealed, moisture-resistant bags to prevent oxidation of metallic components.
- Temperature Limits: Store in a dry environment between -10°C and 40°C.
- Stacking: Maximum 4 layers to avoid deformation.
- Shelf Life: 18 months in unopened original packaging.
Application Guidelines
The brake shoes mixes are molded under high pressure (10-25 MPa) and bonded to shoe plates using high-temperature adhesives. Post-production testing includes shear strength (≥3.5 MPa) and thermal cycling resistance to ensure reliability. For customized formulations, manufacturers adjust the brake shoes mixture ratios to meet specific OEM or aftermarket requirements.
This advanced blend of metallic robustness and precision engineering ensures reliable braking for motorcycles operating in demanding environments, from urban commutes to competitive racing.
