Introduction to Motorcycle Brake Pads Semi-Metallic Mixture
Motorcycle brake pads semi-metallic mixtures are high-performance brake pads friction materials engineered to deliver reliable stopping power and durability for both urban and off-road riding. This brake pads formula combines metallic fibers (e.g., steel, copper) with organic binders and friction modifiers, balancing heat resistance, wear tolerance, and cost-effectiveness. Below is a detailed overview of its composition, technical specifications, advantages, and storage guidelines.
Technical Parameters
The table below outlines key properties of semi-metallic brake pads mixes:
| Parameter | Specification | Remarks |
|---|---|---|
| Metallic Content | 30-60% (Steel, Copper, Iron) | Enhances thermal conductivity and durability |
| Friction Coefficient (μ) | 0.35-0.50 (Dry) | Stable performance across 100°C–400°C |
| Density | 2.4-2.8 g/cm³ | Optimizes weight and structural integrity |
| Operating Temperature | -30°C to 500°C | Resists brake fade under heavy use |
| Compressive Strength | ≥250 MPa | Ensures resistance to hydraulic pressure |
| Wear Rate | ≤0.6 cm³/MJ | Extended service life for high-mileage applications |
| Shore Hardness | 55-70 Shore D | Minimizes rotor wear and noise generation |
Key Advantages
- Enhanced Durability
The brake pads mixture integrates steel and copper fibers, providing superior resistance to wear and tear, even in aggressive braking scenarios. - Thermal Stability
Semi-metallic brake pads friction materials maintain consistent friction coefficients at high temperatures, reducing the risk of brake fade during prolonged downhill rides. - Cost-Effectiveness
Compared to ceramic or carbon-fiber alternatives, semi-metallic brake pads mixes offer a lower price point while retaining robust performance. - Noise Reduction
Graphite or rubber additives in the brake pads formula dampen vibrations, ensuring quieter operation compared to fully metallic variants. - Environmental Compatibility
Free from asbestos and heavy metals, aligning with global eco-friendly manufacturing standards.
Storage and Packaging
- Moisture Protection: Packed in vacuum-sealed, anti-corrosion bags to prevent oxidation of metallic components.
- Temperature Control: Store in a dry environment below 35°C to avoid binder degradation.
- Stacking Limit: Maximum 8 layers to prevent deformation of the friction surface.
- Shelf Life: 18 months in unopened, original packaging.
Application of Brake Pads Mixes
Semi-metallic brake pads mixes are molded under high pressure (10-20 MPa) and cured to ensure adhesion to the backing plate. Post-production, they undergo rigorous testing for shear strength (≥3.5 MPa) and thermal cycling resistance. Custom formulations are available to meet OEM or aftermarket requirements, such as adjusting metallic ratios for specific rotor compatibility.
This blend of affordability, durability, and performance makes semi-metallic brake pads a preferred choice for riders seeking reliability in diverse riding conditions.
