Introduction to Motorcycle Brake Shoes Scorched Mixture
Motorcycle brake shoes scorched mixtures are specialized brake shoes friction materials designed for high-performance applications, combining heat-resistant metallic alloys, ceramic particles, and organic binders through a scorching (high-temperature sintering) process. This brake shoes formula ensures exceptional thermal stability, wear resistance, and consistent friction output, making it ideal for sports bikes and off-road motorcycles operating under extreme conditions. Below is a detailed overview of its composition, technical specifications, advantages, and storage protocols.
Technical Parameters
The table below summarizes key properties of scorched brake shoes mixes:
| Parameter | Specification | Remarks |
|---|---|---|
| Metallic Content | 40-55% (Iron, Copper, Zinc alloys) | Enhances heat dissipation and structural integrity |
| Ceramic Additives | 10-20% (Silicon Carbide, Alumina) | Reduces thermal fade and noise |
| Density | 2.8-3.5 g/cm³ | Optimized for high-pressure resistance |
| Friction Coefficient (μ) | 0.38-0.48 (Dry) | Stable at 200–800°C |
| Operating Temperature | -30°C to 850°C | Superior heat tolerance vs. organic pads |
| Compressive Strength | ≥320 MPa | Withstands aggressive braking forces |
| Wear Rate | ≤0.4 cm³/MJ | 30% lower than standard metallic mixes |
| Shore Hardness | 70-85 Shore D | Minimizes drum glazing |
Key Advantages
- Extreme Heat Resistance
The brake shoes mixture maintains stable friction even during prolonged downhill braking or track use, thanks to its sintered metallic-ceramic matrix. - Enhanced Durability
Scorched brake shoes friction materials exhibit 20% lower wear rates than conventional semi-metallic pads, extending service life to 15,000–25,000 km. - Vibration Damping
Ceramic additives reduce high-frequency noise and shudder, ensuring smooth braking. - Quick Recovery from Wet Conditions
Hydrophobic binders in the brake shoes formula minimize performance degradation in rain or mud. - Eco-Friendly Composition
Asbestos-free and low-copper formulation complies with global environmental regulations.
Storage and Packaging
- Moisture Protection: Packaged in vacuum-sealed, anti-corrosion aluminum foil bags to prevent oxidation of metallic components.
- Temperature Limits: Store at 10°C–35°C; avoid freezing to maintain binder flexibility.
- Stacking: Max 3 layers to prevent deformation of pre-molded friction layers.
- Shelf Life: 18 months in unopened packaging; resealable bags for partial usage.
Application of Brake Shoes Mixes
The brake shoes mixes are manufactured through high-pressure sintering (25–40 MPa) at 800–1,000°C, bonding the friction layer to steel backing plates. Post-production tests include thermal shock cycles (1,000 cycles at 850°C) and shear strength validation (≥4.0 MPa). Custom formulations are available for racing teams requiring tailored friction profiles.
By integrating scorched sintering technology with advanced materials, this brake shoes mixture sets a new benchmark for reliability and performance in motorcycle braking systems.
