Advantages of Asbestos-Free Brake Shoes
- Eco-Safe Composition
- The Brake Shoes Mixes eliminate carcinogenic asbestos fibers, complying with EU REACH and US EPA standards.
- Contains recycled materials (up to 15% post-industrial steel fibers).
- Enhanced Thermal Stability
- Maintains stable friction coefficient across 550°C, reducing brake fade during heavy loads.
- Low Noise & Vibration
- Optimized brake shoes friction materials (ceramic particles + aramid fibers) reduce noise by 40% compared to traditional formulas.
- Corrosion Resistance
- Non-hygroscopic formula prevents moisture absorption, extending service life by 25% in humid climates.
Storage & Packaging Guidelines
- Packaging:
- Individually wrapped in anti-oxidation paper.
- Stacked in reinforced wooden crates with desiccant packets (humidity <55% RH).
- Storage:
- Temperature: 5°C–30°C in dry, ventilated warehouses.
- Avoid direct sunlight; maximum stacking height: 6 layers.
Key Formula Components
The brake shoes formula integrates:
- Friction Modifiers: Graphite (10–12%), zirconium silicate (8–10%)
- Binders: Modified phenolic resin (12–15%)
- Reinforcements: Ceramic fibers (20–25%), aramid pulp (5–8%)
This brake shoes mixture is ideal for commercial vehicles and heavy-duty applications, offering balanced wear resistance and environmental safety.
