• Overall height of 2.04 inches (51.9 mm)
• Outside diameter of 11.91 inches (302.6 mm)
• Five mounting bolt holes with a 4.65 inch (118 mm) bolt circle diameter
• Non-directional brake surface for versatile installation
• Conventional rotor type compatible with standard braking systems

Technical Details and Construction

The BR55034 rotor is constructed from full cast iron, providing a solid and durable braking surface. Its vented design allows air to flow between the rotor faces, helping to reduce heat buildup during braking and maintain consistent performance. The rotor’s nominal thickness of 1.27 inches ensures a robust braking surface, while the discard thickness of 1.21 inches indicates when replacement is necessary to maintain safety and effectiveness. With an outside diameter of 11.91 inches and an overall height of 2.04 inches, this rotor fits specific GM models requiring these dimensions.

Compatible Vehicles and Applications

This DuraGo disc brake rotor is compatible with a variety of GM vehicles, including:

• Buick Aurora, LeSabre, Park Avenue
• Cadillac DeVille, Eldorado, Seville
• Chevrolet Camaro, Impala, Monte Carlo
• Oldsmobile Intrigue
• Pontiac Bonneville, Firebird, Riviera

It is designed for use in conventional braking systems without ABS tone rings and fits vehicles with five mounting bolts.

Common Issues Addressed by This Rotor

• Brake pulsation or vibration due to warped rotors
• Reduced braking efficiency from worn or thin rotors
• Overheating caused by insufficient rotor ventilation
• Noise or squealing from uneven rotor surfaces
• Brake fade during extended or heavy braking

Installation Notes and Tips

When installing the DuraGo BR55034 rotor, ensure the mounting surface is clean and free of rust or debris. Verify the rotor thickness before installation to confirm it meets the nominal specifications. Since this rotor is non-directional, it can be installed on either side of the vehicle. Use proper torque specifications for the five mounting bolts to avoid rotor warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
