Introduction to Truck Brake Linings Anti-Wear Mixture
Truck brake linings anti-wear mixtures are specialized brake linings friction materials designed to maximize durability and performance under extreme operational stress. These brake linings mixes integrate advanced wear-resistant additives, metallic reinforcements, and heat-stable binders, ensuring extended service life and consistent braking efficiency. Below is a detailed overview of their composition, technical specifications, advantages, and storage guidelines.
Technical Parameters
The table below outlines key properties of a typical anti-wear brake linings formula:
| Parameter | Specification | Remarks |
|---|---|---|
| Density | 3.0–3.5 g/cm³ | High-density structure for wear resistance |
| Friction Coefficient (μ) | 0.38–0.48 (Dry) | Stable across wet and dry conditions |
| Operating Temperature | -40°C to 650°C | Resists thermal degradation |
| Wear Rate | ≤0.3 cm³/MJ | Superior to conventional materials |
| Compressive Strength | ≥320 MPa | Withstands high-pressure braking |
| Shore Hardness | 65-80 Shore D | Optimized for drum/pad compatibility |
| Metal Content | 40-60% (Iron, Copper) | Enhances heat dissipation and wear resistance |
Key Advantages
- Exceptional Wear Resistance
The brake linings mixture incorporates hardened metallic particles and ceramic additives, reducing material loss by 30% compared to standard formulations . - Thermal Stability
Engineered to maintain friction efficiency even at 650°C, minimizing brake fade during prolonged downhill braking . - Noise Reduction
Layered graphite and rubber particles in the brake linings friction materials dampen vibrations, reducing squeal . - Eco-Friendly Composition
Asbestos-free formula compliant with global safety standards (e.g., ISO 9001) . - Versatility
Compatible with both drum and disc brake systems for trucks and heavy-duty vehicles .
Storage and Packaging
- Moisture Protection: Sealed in vacuum-packed, moisture-resistant cartons to prevent oxidation .
- Temperature Limits: Store in dry environments between -10°C and 40°C.
- Stacking: Maximum 6 layers to avoid deformation of the friction layer.
- Shelf Life: 18 months in unopened original packaging .
Application of Brake Linings Mixes
The brake linings mixes are compression-molded under 20–35 MPa pressure and cured at 180–220°C to ensure adhesion to the backing plate . Post-production quality tests include thermal shock cycling and shear strength validation (≥4.0 MPa) .
Customized formulations are available to meet OEM specifications for specific truck models or operating environments .
This anti-wear formula combines cutting-edge material science with rigorous engineering, delivering reliable and cost-effective braking solutions for commercial fleets and logistics operators.
