Introduction to Motorcycle Brake Pads Brass-Free Mixture
Motorcycle brake pads brass-free mixtures are eco-friendly brake pads friction materials designed to meet stringent environmental regulations while maintaining high-performance braking. By eliminating brass and other heavy metals, this brake pads formula prioritizes sustainability without compromising safety or durability. Below is a detailed analysis of its composition, technical specifications, advantages, and storage guidelines.
Technical Parameters
The table below outlines key properties of brass-free brake pads mixes:
| Parameter | Specification | Remarks |
|---|---|---|
| Metal Content | ≤0.1% (Steel fibers, no brass/copper) | Complies with EU Regulation No 458/2011 |
| Density | 2.4-2.8 g/cm³ | Lightweight yet robust design |
| Friction Coefficient (μ) | 0.38-0.48 (Dry) | Stable across urban and off-road conditions |
| Operating Temperature | -30°C to 550°C | Resists thermal degradation |
| Compressive Strength | ≥280 MPa | Ensures structural integrity under load |
| Wear Rate | ≤0.6 cm³/MJ | Extended lifespan compared to brass-based pads |
| Shore Hardness | 55-70 Shore D | Optimized for disc compatibility |
Key Advantages
- Eco-Friendly Composition
The brake pads mixture excludes brass and copper, reducing environmental contamination and aligning with global regulations (e.g., EU and North America). - Reduced Rotor Wear
Ceramic and aramid fiber additives minimize abrasion on brake discs, lowering maintenance costs. - Consistent Performance
The brake pads formula maintains stable friction levels even in wet or high-humidity conditions, critical for motorcycle safety. - Noise Reduction
Integrated damping agents (e.g., rubberized cork) suppress squeal and vibration. - Thermal Stability
High-temperature resins and ceramic particles prevent fade during aggressive braking.
Storage and Packaging
- Moisture Protection: Packed in vacuum-sealed, aluminum-coated bags to prevent oxidation.
- Temperature Limits: Store in environments between -20°C and 35°C to avoid binder degradation.
- Stacking: Max 10 layers to prevent deformation of friction material.
- Shelf Life: 18 months in unopened packaging; label with batch number and production date for traceability.
Application of Brake Pads Mixes
The brake pads mixes are molded under 10-20 MPa pressure and cured at 150-200°C to bond the friction layer to the backing plate. Post-production testing includes shear strength checks (≥3.5 MPa) and thermal shock resistance evaluations . Customizable formulations are available for racing or commuter motorcycles, adjusting additives like graphite or silica for specific use cases.
By integrating advanced materials with sustainable design, brass-free brake pads ensure reliable braking performance while addressing ecological concerns in the automotive industry.
