Detailed Product Description

The DuraGo BR900618 disc brake rotor is manufactured from cast iron, a material known for its excellent thermal conductivity and wear resistance. This rotor features a solid, non-vented design with a nominal thickness of 0.43 inches, ensuring consistent braking performance under normal driving conditions. Its drum-in-hat construction integrates a parking brake drum within the rotor, making it compatible with vehicles equipped with drum-in-hat parking brake systems. The rotor’s 5-bolt mounting pattern and precise center hole diameter of 2.64 inches ensure a secure fit on Mercedes-Benz CL500, S350, S430, and S500 models. This rotor does not include an ABS tone ring and lacks rust-resistant coating, so proper maintenance is recommended to prevent corrosion over time.

Compatible Vehicles and Applications

• Mercedes-Benz CL500
• Mercedes-Benz S350
• Mercedes-Benz S430
• Mercedes-Benz S500

This rotor is designed to replace worn or damaged front or rear disc brake rotors on these specific Mercedes-Benz models, restoring braking efficiency and safety.

Common Issues Addressed by DuraGo BR900618

• Brake pulsation caused by warped rotors
• Reduced braking performance due to worn rotor thickness
