Detailed Product Description

The DuraGo BR34211 is a full cast disc brake rotor constructed from high-quality cast iron, providing a solid and reliable braking surface. Its vented design enhances airflow between the rotor faces, helping to reduce heat buildup during braking and maintain consistent stopping power. With a nominal thickness of 0.98 inches and a discard thickness of 0.92 inches, this rotor offers a balance between durability and service life. The 12.8-inch outside diameter and 5-bolt mounting pattern with a 4.72-inch bolt circle diameter ensure compatibility with specific BMW models including the 330Ci, 330i, 330xi, and Z4. The rotor features a non-directional braking surface, allowing for flexible installation without concern for rotor orientation. This conventional rotor does not include an ABS tone ring, so it is intended for vehicles without ABS sensor integration on the rotor itself.

Compatible Vehicles and Applications

• BMW 330Ci
• BMW 330i
• BMW 330xi
• BMW Z4

This rotor is designed to replace worn or damaged front or rear rotors on these BMW models, restoring braking performance and safety.

Common Issues Addressed by DuraGo BR34211

• Brake pulsation caused by warped rotors
• Reduced braking efficiency due to worn rotor thickness
• Overheating and brake fade from insufficient heat dissipation
• Noise and vibration from uneven rotor surfaces
• Corrosion-related rotor damage (note: this rotor does not have rust-resistant coating)

Installation Notes and Tips

When installing the DuraGo BR34211 rotor, ensure the mounting surface is clean and free of debris to prevent uneven rotor seating. Since this rotor is non-directional, it can be installed on either side without concern for rotation direction. Verify that the rotor thickness is within the nominal range and above the discard thickness before installation. Use proper torque specifications for the 5 mounting bolts to avoid rotor warping. This rotor is compatible with vehicles that do not require an ABS tone ring on the rotor itself.

Quality Assurance and Warranty

DuraGo manufactures the BR34211 rotor to meet or exceed OEM specifications for fit, form, and function. The cast iron construction and vented design contribute to consistent braking performance under normal operating conditions. While this rotor does not include a rust-resistant coating, proper maintenance can help extend its service life. Warranty coverage details should be confirmed with the product documentation or supplier.
