Durable Construction and Design Features

The DuraGo BR5551 rotor is made from cast iron, a material known for its excellent wear resistance and heat management. Its full cast construction provides a solid, reliable braking surface. The vented design allows air to flow between the rotor faces, reducing heat buildup during braking and helping to prevent warping. With a nominal thickness of 1.04 inches and a discard thickness of 0.96 inches, this rotor offers a balance between longevity and safety, ensuring it can be resurfaced or replaced at the appropriate intervals. The rotor’s 10.49-inch outside diameter and 2.41-inch overall height are engineered to match the specifications required for Chevrolet Camaro and Pontiac Firebird vehicles, ensuring proper fit and function.

Compatible Vehicles and Applications

This disc brake rotor is compatible with select Chevrolet Camaro and Pontiac Firebird models. It is designed for use in conventional braking systems without ABS tone rings and fits vehicles requiring a 5-bolt mounting pattern with a 4.75-inch bolt circle diameter. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

  • Replaces worn or damaged rotors on Chevrolet Camaro and Pontiac Firebird
  • Addresses issues such as brake pulsation and uneven wear
  • Helps resolve noise or vibration during braking
  • Restores braking efficiency and pedal feel
  • Prevents rotor warping caused by excessive heat

Installation Notes and Tips

When installing the DuraGo BR5551 rotor, ensure the mounting surface is clean and free of rust or debris to promote proper seating. Since this rotor does not include an ABS tone ring, verify compatibility with your vehicle’s ABS system before installation. Use the correct torque specifications for the five mounting bolts to avoid rotor distortion. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.
