Product Descreiption
The Dongfeng MK01C Brake Drum is a premium braking component designed for the rear axle systems of medium- and heavy-duty commercial vehicles, including trucks, buses, and specialized transport equipment. Engineered to deliver consistent stopping power, superior heat dissipation, and long-lasting durability, the MK01C brake drum is a critical safety component for vehicles operating under demanding conditions. Built to Dongfeng’s rigorous OEM standards, this brake drum combines advanced materials, precision manufacturing, and optimized thermal design to ensure reliable performance, reduced maintenance costs, and enhanced driver safety.
Key Specifications
- Application Compatibility:
- Vehicle Models: Fits Dongfeng’s popular models such as the DFL series (e.g., DFL5160, DFL5250), Tianlong series, and other heavy-duty trucks (4×2, 6×4, and 8×4 configurations).
- Axle Type: Designed for rear drum brake systems, compatible with 10-ton to 13-ton capacity axles.
- Material & Construction:
- Brake Drum Body: High-grade cast iron (e.g., GG25 or FC250) with a balanced graphite microstructure for improved thermal stability and crack resistance.
- Surface Finish: Precision-machined braking surface with a roughness of ≤ Ra 3.2 μm, ensuring uniform friction and minimizing brake fade.
- Heat Treatment: Annealed and stress-relieved to prevent warping during high-temperature braking cycles.
- Dimensions:
- Outer Diameter: ~380–400 mm (14.96–15.75 inches) (varies by vehicle model).
- Inner Diameter (Braking Surface): ~340–360 mm (13.39–14.17 inches).
- Width: ~120–140 mm (4.72–5.51 inches).
- Bolt Circle Diameter (PCD): 10 x 285 mm (10-bolt pattern, 285 mm pitch circle diameter) or 8 x 275 mm (customizable for specific axles).
- Center Bore: ~160–170 mm (6.30–6.69 inches).
- Weight: ~35–45 kg (77.2–99.2 lbs) (depending on size and material).
- Braking Performance:
- Maximum Operating Temperature: Up to 600°C (1,112°F) without deformation.
- Thermal Conductivity: High iron content ensures rapid heat dissipation, reducing the risk of brake overheating.
- Friction Coefficient: Compatible with standard semi-metallic or low-metallic brake linings.
- Load Rating:
- Static Load Capacity: Up to 13,000 kg (28,660 lbs) per drum (designed for GAWR ≤26,000 kg rear axles).
- Dynamic Load Rating: Meets ISO 26867:2009 and GB/T 5763 standards for commercial vehicle brake drums.
Technical Features
- Optimized Heat Management:
- Reinforced rib design increases surface area for improved cooling, minimizing brake fade during prolonged use.
- Uniform wall thickness (22–28 mm) balances weight and thermal performance.
- Durability & Longevity:
- High-carbon cast iron resists cracking and spalling under repeated thermal stress.
- Corrosion-resistant coatings (e.g., black oxide or zinc phosphate) protect against rust in harsh environments.
- Precision Engineering:
- Tight dimensional tolerances (≤0.1 mm runout) ensure even brake lining wear and smooth operation.
- Compatible with automatic slack adjusters for reduced maintenance.
- Easy Installation & Maintenance:
- Direct OEM replacement for part number MK01C, ensuring seamless fitment.
- Modular design allows for quick inspection and replacement without axle disassembly.
