About the Raybestos Specialty - Truck; Coated Rotor Line

The Specialty - Truck; Coated Rotor line by Raybestos is designed specifically for truck applications requiring robust braking components. This product line focuses on providing rotors with protective coatings and solid construction to withstand the rigors of commercial and heavy-duty use. The 982639 rotor fits within this line, offering a coated surface that helps resist corrosion and extends rotor life on Mercedes-Benz Sprinter trucks.

Technical Details and Specifications

This disc brake rotor is made from cast iron, a material known for its excellent thermal conductivity and wear resistance. The rotor features a solid design with a smooth surface type, which promotes even brake pad wear and reliable stopping power. The nominal thickness of 0.709 inches (18.000 mm) ensures structural integrity, while the discard thickness of 0.630 inches (16.000 mm) indicates when replacement is necessary to maintain safe braking performance. The rotor’s outside diameter of 11.728 inches (297.900 mm) and inside diameter of 8.016 inches (203.600 mm) are engineered to match the specifications required for Mercedes-Benz Sprinter 1500, 2500, 3500, and 3500XD models. The six mounting bolt holes with a 130 mm bolt circle diameter provide a secure fitment on the vehicle’s hub assembly.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mercedes-Benz Sprinter trucks
• Addresses brake pulsation and vibration issues caused by uneven rotor surfaces
• Helps restore proper braking performance and pedal feel
• Prevents premature brake pad wear due to rotor surface irregularities
• Suitable for commercial and heavy-duty driving conditions requiring reliable stopping power

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is above the discard limit of 0.630 inches (16.000 mm) to maintain safety standards. Use proper torque specifications on the six mounting bolts to secure the rotor firmly. It is recommended to replace brake pads simultaneously to optimize braking performance and avoid uneven wear. Always inspect the hub assembly for damage or corrosion prior to installation.
