Introduction to Motorcycle Brake Shoes Less Metallic Mixture
Motorcycle brake shoes less metallic mixtures are specialized brake shoes friction materials designed to balance braking efficiency, environmental compatibility, and noise reduction for urban and recreational riding. By reducing metallic content (typically below 30%) and incorporating organic fibers, ceramic particles, and advanced binders, this brake shoes formula minimizes rotor wear while maintaining reliable stopping power. Below is a detailed breakdown of its composition, technical specifications, advantages, and storage protocols.
Technical Parameters
The table below highlights key properties of a typical brake shoes mixture with reduced metallic content:
| Parameter | Specification | Remarks |
|---|---|---|
| Metallic Content | 20-30% (Steel fibers, Copper flakes) | Reduces rotor abrasion |
| Density | 2.0-2.4 g/cm³ | Lightweight design for agility |
| Friction Coefficient (μ) | 0.35-0.42 (Dry) | Smooth engagement in varied conditions |
| Operating Temperature | -30°C to 450°C | Suitable for frequent stops |
| Compressive Strength | ≥150 MPa | Resilient under moderate hydraulic loads |
| Wear Rate | ≤0.3 cm³/MJ | Extended lifespan (15,000–25,000 km) |
| Shore Hardness | 50-65 Shore D | Optimized for drum/disc compatibility |
Key Advantages
- Reduced Rotor Wear
The low metallic brake shoes mixes minimize scoring on brake discs, prolonging rotor life. - Quiet Operation
Organic additives (aramid, rubber-cork) dampen vibrations and eliminate squeal. - Eco-Friendly Composition
Non-asbestos, low-copper formulations comply with global environmental regulations. - Thermal Adaptability
Ceramic particles enhance heat dissipation, preventing fade during urban stop-and-go traffic. - Lightweight Design
Lower density (2.0–2.4 g/cm³) improves motorcycle handling and fuel efficiency.
Storage and Packaging
- Moisture Protection: Sealed in vacuum-packed, moisture-resistant bags to prevent binder degradation.
- Temperature Limits: Store below 35°C to avoid premature curing of organic components.
- Stacking: Maximum 4 layers to prevent deformation of friction linings.
- Shelf Life: 18 months in unopened, original packaging.
Application of Brake Shoes Formula
The brake shoes mixes are cold-pressed at 10–20 MPa and heat-cured to bond friction layers to aluminum or steel shoe plates. Post-production testing includes shear strength (≥2.5 MPa) and humidity resistance (85% RH, 48 hours) to ensure durability in humid climates.
For performance-oriented models, manufacturers adjust the brake shoes mixture ratios to prioritize heat resistance or noise suppression.
This innovative blend of organic and metallic components ensures reliable, eco-conscious braking for motorcycles in diverse riding conditions.
