Durable Cast Iron Disc Brake Rotor for GM Trucks and SUVs

The DuraGo BR55067 disc brake rotor is engineered for reliable braking performance on select Cadillac, Chevrolet, and GMC models. Designed with a full cast iron construction and vented design, this rotor provides consistent heat dissipation and durability for vehicles like the Chevrolet Silverado 1500 and GMC Sierra 1500.

• Material: Cast iron for strength and heat resistance
• Vented rotor design to improve cooling and reduce brake fade
• Drum-in-hat construction integrates parking brake drum
• Nominal thickness of 1.19 inches (30.1 mm) with discard thickness at 1.12 inches (28.5 mm)
• Outside diameter of 12.99 inches (330 mm) with 6 mounting bolt holes
• Non-directional brake surface for versatile installation
• Compatible with multiple GM full-size trucks and SUVs

Technical Details and Construction

The BR55067 rotor features a full cast iron build, providing a solid and durable braking surface. Its vented design allows air to flow between the rotor faces, helping to dissipate heat generated during braking. This reduces the risk of brake fade and extends rotor life. The drum-in-hat construction includes an integrated parking brake drum, eliminating the need for a separate drum component. With a nominal thickness of 1.19 inches and a discard thickness of 1.12 inches, this rotor meets OEM specifications for thickness and wear limits. The rotor measures 12.99 inches in diameter and has six mounting bolt holes arranged on a 5.5-inch bolt circle diameter, ensuring proper fitment on compatible vehicles.

Compatible Vehicles and Applications

This DuraGo disc brake rotor is compatible with a range of GM trucks and SUVs, including:

• Cadillac Escalade, Escalade ESV, and Escalade EXT
• Chevrolet Avalanche 1500, Silverado 1500, Suburban 1500, Tahoe, and Express 1500
• GMC Sierra 1500, Yukon, Yukon XL 1500, and Savana 1500

It is designed to replace original equipment rotors on these models, providing reliable braking performance for daily driving and towing applications.

Common Issues Addressed by This Rotor

• Brake pulsation or vibration due to warped rotors
• Reduced braking efficiency from worn or thin rotors
• Overheating and brake fade during heavy use
• Noise or squealing caused by uneven rotor surfaces
• Parking brake malfunction related to drum-in-hat rotor wear

Installation Notes and Tips

When installing the DuraGo BR55067 rotor, ensure the rotor surface is clean and free of rust or debris. Verify the rotor thickness is above the discard limit before installation. Use proper torque specifications for the six mounting bolts to avoid rotor warping. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. The non-directional design allows installation on either side of the vehicle without concern for rotor orientation.

Quality Assurance and Warranty

DuraGo rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The BR55067 rotor undergoes rigorous quality control to ensure consistent performance and durability. While this product does not include a rust-resistant coating, its cast iron construction provides reliable wear resistance. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
