• Vented rotor design to improve cooling and reduce brake fade
• Nominal thickness of 0.98 inches (25 mm) with discard thickness at 0.88 inches (22.4 mm)
• Outside diameter of 11.57 inches (294 mm) suitable for specified Mercedes-Benz models
• Five mounting bolt holes with a 4.41 inch (112 mm) bolt circle diameter
• Non-directional brake surface for flexible installation
• Conventional rotor type without ABS tone ring

Detailed Product Description

The DuraGo BR34115 disc brake rotor is constructed from full cast iron, providing a solid and durable braking surface. Its vented design allows air to flow between the rotor surfaces, enhancing heat dissipation during braking and helping to maintain consistent stopping power. With an overall height of 1.95 inches (49.5 mm) and a center hole diameter of 2.64 inches (67 mm), this rotor is engineered to fit precisely on Mercedes-Benz 400E, E320, and E420 models. The rotor features five mounting bolt holes, each 0.59 inches (15 mm) in diameter, arranged on a 4.41 inch (112 mm) bolt circle diameter, ensuring secure attachment to the wheel hub.

Compatible Vehicles and Applications

This disc brake rotor is compatible with the following Mercedes-Benz models:

• Mercedes-Benz 400E
• Mercedes-Benz E320
• Mercedes-Benz E420

It is designed for use in standard braking systems without ABS tone rings and is suitable for vehicles requiring a conventional, non-directional rotor.

Common Issues Addressed by DuraGo BR34115

• Brake rotor warping due to heat buildup
• Reduced braking efficiency from worn or thin rotors
• Brake noise caused by uneven rotor surfaces
• Vibration or pulsation during braking
• Corrosion-related rotor damage (note: this rotor does not have rust-resistant coating)

Installation Notes and Tips

When installing the DuraGo BR34115 rotor, ensure the mounting surface is clean and free of debris to prevent uneven rotor seating. Verify the rotor thickness before installation; replace if below the discard thickness of 0.88 inches (22.4 mm). Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s braking system. Proper torque specifications should be followed for the five mounting bolts to ensure secure fitment and optimal performance.

Quality Assurance and Warranty

DuraGo manufactures the BR34115 rotor to meet or exceed OEM specifications for Mercedes-Benz 400E, E320, and E420 models. The full cast iron construction and vented design contribute to reliable braking performance. While this rotor does not feature a rust-resistant coating, it is engineered for durability under normal operating conditions. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
