Key Advantages
- Superior Thermal Management
The ceramic-based brake shoes mixture excels in dissipating heat, preventing brake fade even during prolonged downhill braking . - Low Wear and Corrosion Resistance
Ceramic components and carbon fibers reduce wear rates by up to 50% compared to metallic alternatives, while resisting moisture-induced corrosion . - Noise and Dust Reduction
The brake shoes friction materials incorporate vibration-dampening additives, minimizing brake squeal and generating less airborne dust. - Eco-Friendly Performance
Free from copper and asbestos, this brake shoes formula aligns with global environmental regulations . - Consistent Braking Efficiency
Maintains stable friction coefficients across diverse conditions, ensuring reliable stopping power in extreme temperatures or wet environments.
Storage and Packaging Guidelines
- Moisture Protection: Store in vacuum-sealed, moisture-resistant packaging to prevent ceramic matrix hydration .
- Temperature Limits: Avoid prolonged exposure to temperatures exceeding 50°C or below -20°C.
- Stacking: Limit stacking to 4 layers to avoid structural deformation.
- Shelf Life: 18–24 months in unopened, original packaging .
Application of Brake Shoes Mixes
The brake shoes mixes are precision-molded under high pressure (20–35 MPa) and sintered at 1,200°C to ensure bonding strength between the ceramic layer and shoe plate. Post-production, they undergo rigorous testing for shear strength (≥3.5 MPa) and thermal shock resistance . Customizable formulations are available to meet OEM-specific requirements, such as enhanced cold-weather performance or reduced rotor wear.
This ceramic-based innovation sets a new benchmark for safety and durability in commercial vehicle braking systems, combining advanced materials with sustainable design principles.
