Key Advantages
- Low Noise & Dust Emission
- The Brake Shoes Mixes integrate ceramic fibers (35–40%) and aramid particles (10–12%), reducing vibration-induced noise to <65 dB at 80 km/h braking.
- Dust emission reduced by 60% compared to metallic formulations.
- Thermal Stability
- Maintains stable friction coefficient from -30°C to 750°C, preventing brake fade during prolonged downhill driving.
- Eco-Friendly Composition
- Free from copper, asbestos, and heavy metals, compliant with EU Regulation No 305/2011 and US EPA standards.
- Extended Service Life
- Ceramic brake shoes friction materials exhibit 30% lower wear rates than semi-metallic counterparts, doubling rotor lifespan.
Storage & Packaging Guidelines
- Packaging:
- Individually wrapped in anti-corrosion VCI (Volatile Corrosion Inhibitor) paper.
- Stacked in reinforced cartons with desiccant packs (max humidity: 50% RH).
- Storage:
- Temperature: 5°C–30°C in UV-protected, ventilated warehouses.
- Avoid direct ground contact; pallet stacking ≤8 layers.
Formula Composition
The brake shoes formula comprises:
- Ceramic Base: 45–50% ceramic fibers (Al₂O₃-SiO₂ composite)
- Friction Modifiers: Graphite (8–10%), zirconium silicate (5–7%)
- Binders: Modified phenolic resin (12–15%)
- Reinforcements: Aramid pulp (8–10%), glass microspheres (3–5%)
This balanced Brake Shoes Mixture ensures optimal heat dissipation and wear resistance, ideal for passenger vehicles and hybrid/electric cars.
