Detailed Product Description

The DuraGo BR55069 is a conventional, vented disc brake rotor constructed from full cast iron, providing a balance of durability and thermal management. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to maintain consistent stopping power. With a nominal thickness of 1.15 inches (29.1 mm) and a discard thickness of 1.08 inches (27.5 mm), this rotor meets the specifications required for safe and effective brake performance. The rotor measures 12.01 inches (305 mm) in outside diameter and features six mounting bolt holes arranged on a 5-inch (127 mm) bolt circle diameter, ensuring compatibility with specific vehicle models.

This rotor is designed without a rust-resistant coating and does not include an ABS tone ring, making it suitable for vehicles that do not require these features. The non-directional brake surface allows for installation on either side of the vehicle without concern for rotor orientation. The overall height of 2.14 inches (54.3 mm) and center hole diameter of 3.12 inches (79.2 mm) align with factory specifications for a proper fit.

Compatible Vehicles and Applications

This DuraGo disc brake rotor BR55069 is compatible with a range of vehicles including Buick, Chevrolet, GMC, Isuzu, and Oldsmobile models. Specifically, it fits the Chevrolet Trailblazer, GMC Envoy, Buick Rainier, Isuzu Ascender, and Oldsmobile Bravada. It is designed to replace worn or damaged rotors on these vehicles, restoring braking efficiency and safety.

• Addresses brake pulsation and vibration issues
• Replaces rotors worn below discard thickness
• Improves braking performance on vented rotor-equipped vehicles
• Eliminates noise caused by warped or damaged rotors
• Restores proper rotor thickness for safe braking

Installation Notes and Tips

When installing the DuraGo BR55069 rotor, ensure the vehicle is securely lifted and the wheel assembly is removed. Clean the hub surface to remove rust and debris before mounting the rotor. Since this rotor is non-directional, it can be installed on either side of the vehicle. Verify that the rotor thickness is within the nominal range and above the discard thickness before installation. Torque the mounting bolts to manufacturer specifications and inspect brake pads for wear during the process.

Quality Assurance and Warranty

DuraGo manufactures the BR55069 rotor to meet or exceed OEM standards for fit, form, and function. The cast iron construction and vented design provide reliable performance under normal driving 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.
