Advantages of Metallic-Free Brake Shoes
- Eco-Friendly Composition
- The Brake Shoes Formula contains no heavy metals or asbestos, complying with EU REACH and RoHS regulations.
- 100% recyclable materials reduce landfill waste by 25% compared to traditional metallic blends.
- Noise Reduction & Smooth Braking
- Ceramic fibers and aramid particles in the brake shoes friction materials dampen vibrations, achieving noise levels <68 dB at 80 km/h braking.
- Corrosion Resistance
- Non-metallic brake shoes mixes resist saltwater and humidity, extending service life by 20% in coastal climates.
- Thermal Stability
- Maintains consistent friction coefficient across extreme temperatures (-30°C to 600°C), preventing brake fade during prolonged use.
Storage & Packaging Guidelines
- Packaging:
- Individually wrapped in anti-static, moisture-proof bags with desiccants.
- Stacked in reinforced cartons (max 10 pairs per box) labeled with batch numbers and production dates.
- Storage:
- Temperature: 5°C–30°C in dry, ventilated areas away from direct sunlight.
- Avoid stacking >6 layers to prevent deformation.
Core Formula Components
The brake shoes mixture comprises:
- Friction Modifiers: Graphite (10–12%), boron nitride (5–8%)
- Binders: Modified phenolic resin (12–15%)
- Reinforcements: Ceramic fibers (30–35%), glass wool (8–10%)
This brake shoes formula ensures optimal performance for commercial vehicles and urban driving conditions, balancing durability with environmental sustainability.
