Detailed Product Description

The DuraGo BR34147 is a vented disc brake rotor made from cast iron, providing a balance of durability and heat management essential for braking efficiency. Its full cast construction ensures structural integrity under demanding conditions. The rotor's dimensions, including an outside diameter of 11.93 inches and a nominal thickness of 1.02 inches, align with the original equipment specifications for Mercedes-Benz ML320, ML350, and ML430 models. The vented design helps dissipate heat generated during braking, reducing the risk of brake fade and maintaining consistent performance. This rotor does not include an ABS tone ring and features a non-directional braking surface, allowing for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

• Mercedes-Benz ML320
• Mercedes-Benz ML350
• Mercedes-Benz ML430

This rotor is intended for use in the front or rear disc brake assemblies of the above models, addressing common braking issues such as vibration, noise, and reduced stopping power.

Common Issues Addressed by DuraGo BR34147

• Brake rotor warping causing pedal pulsation
• Reduced braking efficiency due to worn or thin rotors
• Excessive brake noise from uneven rotor surfaces
• Overheating and brake fade during extended use
• Corrosion-related rotor degradation (note: this rotor does not have rust-resistant coating)

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 0.91 inches before installation. Clean the rotor surface to remove any protective coatings or debris. Use proper torque specifications for the five mounting bolts on the 4.41 inch bolt circle diameter. Since this rotor is non-directional, it can be installed on either side without concern for rotation direction. Verify compatibility with your vehicle’s brake system, especially if ABS components are present, as this rotor does not include an ABS tone ring.
