Introduction to No-Brass Formula Truck Brake Linings
Truck brake linings formulated with a no-brass formula represent an innovative advancement in friction material technology. By eliminating brass components, these linings address environmental concerns, reduce wear on brake drums, and comply with stringent regulations such as the U.S. Copper-Free Brake Initiative. The Brake Linings Mixture combines high-performance non-metallic materials, including ceramic fibers, silica-based modifiers, and aramid resins, ensuring durability and consistent friction performance.
Technical Parameters
| Parameter | Value/Range |
|---|---|
| Friction Coefficient (μ) | 0.38–0.48 (dry conditions) |
| Operating Temperature | -30°C to 550°C |
| Density | 2.2–2.5 g/cm³ |
| Compressive Strength | ≥85 MPa |
| Porosity | 12–20% |
| Thickness | 10–25 mm (customizable) |
Key Advantages
- Environmental Compliance
- The Brake Linings Formula excludes brass and other heavy metals, reducing soil and water contamination while meeting global standards like the EU End-of-Life Vehicles Directive.
- Enhanced Durability
- The Brake Linings Friction Materials utilize ceramic-silica composites, which exhibit 25–30% lower abrasion rates compared to brass-containing counterparts, extending brake drum lifespan.
- Thermal Stability
- Optimized Brake Linings Mixes incorporate heat-resistant aramid fibers, maintaining friction stability at temperatures up to 550°C and minimizing brake fade during heavy loads.
- Noise Reduction
- The absence of brass reduces high-frequency vibrations, lowering noise emissions by 10–15 dB during braking, ideal for urban and noise-sensitive environments.
Storage & Packaging
- Packaging:
- Sealed in anti-static, moisture-resistant polyethylene bags, with reinforced steel pallets for bulk shipments (12,000 kg per batch).
- Customizable barcodes and OEM labels for traceability.
- Storage Conditions:
- Store in a dry, temperature-controlled warehouse (humidity <50%, temperature 15–25°C).
- Avoid stacking over 5 layers to prevent deformation.
Applications
Suitable for heavy-duty trucks, municipal vehicles, and mining equipment requiring eco-friendly, low-noise, and high-temperature-resistant braking solutions.
By integrating a no-brass formula and advanced brake linings friction materials, these linings deliver a sustainable and high-performance alternative to traditional brass-based systems. For technical specifications or certifications, consult certified suppliers on platforms like Global Sources.
