Mercedes Heavy Duty Hub Brake Discs

Key Features & Specifications

1. Robust Construction:

• Material: Constructed from high-quality G3000 cast iron (equivalent to GG25/HT250) with ≥95% pearlite content, ensuring superior wear resistance and structural integrity.

• Vented Design: Internally ventilated (e.g., 430mm diameter, 45mm thickness) with optimized vanes for efficient heat dissipation, reducing brake fade during prolonged use.

• Hub Integration: Directly compatible with Mercedes-Benz truck axles, featuring precise centering diameters (e.g., 211mm) and bolt patterns (e.g., 10 holes, 238mm pitch circle diameter) for secure, vibration-free installation.

2. Performance & Compliance:

• ECE R90 Certification: Meets stringent European safety standards for braking efficiency, thermal stability, and corrosion resistance, ensuring roadworthiness across global markets.

• Longevity: Engineered for extended service life, with real-world applications showcasing up to 400,000 km of wear resistance when paired with Mercedes-Benz’s advanced braking systems (e.g., Actros MP4 models).

• Thermal Management: Vented design and heat-resistant materials enable consistent performance even at temperatures exceeding 500°C, critical for heavy-duty operationsspecial.mercedes-benz-trucks.com.

3. System Compatibility:

• Integration with Safety Systems: Works seamlessly with Mercedes-Benz Trucks’ ABS, ESP, and adaptive braking technologies, ensuring balanced stopping power and stability.

• Hybrid & Electric Compatibility: Optimized for use in hybrid and electric truck variants (e.g., Econic NGT), complementing regenerative braking systems.

4. OEM Quality & Reliability:

• Genuine Parts Assurance: Manufactured to Mercedes-Benz’s exact OE specifications, ensuring perfect fitment and compatibility with factory calipers, pads, and hardwarehub.mercedes-benz-trucks.com.

• Warranty: Backed by Mercedes-Benz Trucks’ global warranty, offering peace of mind for fleet operators and owner-drivershub.mercedes-benz-trucks.com.

Applications

• Actros: Long-haul trucks, construction vehicles, and heavy-duty tractors.

• Atego: Light to medium-duty distribution trucks.

• Unimog: All-terrain workhorses for off-road and industrial applications.

• Econic: Urban delivery trucks and specialized municipal vehicles.

Benefits for Fleet Operators

1. Reduced Downtime: Extended service life minimizes replacement frequency, lowering maintenance costs and operational interruptions.

2. Enhanced Safety: ECE R90 compliance and thermal stability reduce the risk of brake failure in critical situations.

3. Fuel Efficiency: Lightweight design (e.g., 23.9 kg for 377mm discs) and optimized heat dissipation contribute to lower energy consumption.

4. Total Cost of Ownership (TCO): Durability and OE compatibility align with Mercedes-Benz’s TCO philosophy, maximizing long-term value.
