Detailed Product Description

The DuraGo BR901584 disc brake rotor is constructed from full cast iron, providing a balance of strength and thermal conductivity essential for consistent braking performance. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking and reducing the risk of brake fade under demanding conditions. With a nominal thickness of 1.26 inches (32 mm) and a discard thickness of 1.18 inches (30 mm), this rotor meets the precise specifications required for safe operation on Mercedes-Benz GL350, GL450, GLE400, GLS350d, GLS450, and ML400 models. The rotor’s 13.78 inch (350 mm) outside diameter and 5-bolt mounting pattern with a 4.41 inch (112 mm) bolt circle diameter ensure proper fitment and secure installation.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thinning
• Eliminating noise and vibration from uneven rotor surfaces
• Improving heat dissipation to prevent brake fade during heavy use
• Restoring proper rotor dimensions for safe braking performance

Installation Notes and Tips

When installing the DuraGo BR901584 rotor, ensure the mounting surface is clean and free of rust or debris to promote proper seating. Verify the rotor thickness before installation to confirm it meets or exceeds the discard thickness of 1.18 inches (30 mm). Use the correct torque specifications for the 5 mounting bolts to avoid warping. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
