Introduction to Motorcycle Brake Pads No Brass Mixture
Motorcycle brake pads with a no brass mixture are an innovative category of brake pads friction materials designed to address environmental concerns while maintaining high-performance braking. This brake pads formula eliminates brass components, reducing heavy metal pollution and aligning with global regulations like the EU’s REACH standards. Below is a detailed analysis of its composition, technical specifications, advantages, and storage protocols.
Technical Parameters
The table below outlines the key properties of a typical no-brass brake pads mixture:
| Parameter | Specification | Remarks |
|---|---|---|
| Primary Components | Ceramic (30-45%), Aramid Fiber (15-25%), Graphite (10-20%) | Eco-friendly, copper-free formula |
| Density | 2.4-2.8 g/cm³ | Lightweight design for reduced rotor wear |
| Friction Coefficient (μ) | 0.38-0.43 (Dry) | Stable performance across 100-600°C |
| Operating Temperature | -30°C to 650°C | Minimal thermal fade at high speeds |
| Wear Rate | ≤0.4 cm³/MJ | Extended lifespan compared to brass-based pads |
| Compressive Strength | ≥280 MPa | Resists deformation under heavy braking |
| Shore Hardness | 55-70 Shore D | Optimized for disc compatibility and noise reduction |
Key Advantages
- Environmental Compliance
The brake pads formula excludes brass and other heavy metals, reducing soil and water contamination during disposal. - Enhanced Durability
Reinforced with aramid fibers and ceramic matrices, the brake pads friction materials exhibit low wear rates and resistance to glazing, even under aggressive riding conditions. - Noise Reduction
Graphite additives dampen vibrations, eliminating high-frequency squeal common in metallic mixes. - Thermal Stability
Ceramic components ensure consistent friction levels during prolonged braking, preventing sudden performance drops. - Disc-Friendly
The brake pads mixes generate less abrasive dust, preserving rotor surface integrity and reducing maintenance costs.
Storage and Packaging
- Moisture Protection: Packaged in vacuum-sealed, aluminum-lined bags to prevent moisture absorption and oxidation.
- Temperature Limits: Store in environments between -20°C and 40°C to maintain material integrity.
- Stacking Guidelines: Maximum 8 layers to avoid compression damage.
- Shelf Life: 18 months in unopened packaging; use within 6 months after opening.
Application Notes
The brake pads mixture is molded under 10-20 MPa pressure and cured at 200-300°C to achieve optimal bonding between the friction layer and backing plate. Post-production testing includes shear strength (≥3.5 MPa) and thermal cycling simulations to ensure reliability in extreme climates. Customizable formulations are available for racing, touring, or urban motorcycles.
By combining advanced materials with eco-conscious engineering, no-brass motorcycle brake pads deliver safety, sustainability, and cost-efficiency for riders and manufacturers alike.
