Key Advantages
- Eco-Friendly Composition
Free from asbestos and heavy metals, this brake linings mixture complies with global environmental standards (e.g., REACH, RoHS) . - Noise Reduction
Ceramic and aramid fibers dampen vibrations, eliminating squeal and ensuring quiet operation . - High-Temperature Resistance
The brake linings friction materials maintain stable performance even under prolonged braking, reducing thermal fade risks . - Comfortable Braking
Smooth friction transitions prevent sudden jolts, enhancing driver control and passenger comfort . - Compatibility
Suitable for both drum and disc brake systems in trucks, buses, and trailers .
Storage and Packaging
- Moisture Protection: Packed in sealed, moisture-resistant polybags and cartons to prevent material degradation .
- Temperature Control: Store in dry environments below 40°C to avoid binder deterioration .
- Stacking Limits: Maximum 5 layers to prevent deformation .
- Shelf Life: 18–24 months in unopened, original packaging .
Application Notes
The brake linings mixes are molded under 10–25 MPa pressure and cured at 150–200°C to ensure adhesion to backing plates. Post-production testing includes thermal cycling (100–600°C) and shear strength validation . Custom formulations are available to meet OEM-specific requirements, such as adjusting ceramic content for extreme climates .
By integrating advanced non-metallic components, this brake linings formula delivers reliable, sustainable braking solutions for modern commercial vehicles.
