Reliable Disc Brake Rotor for Buick, Chevrolet, GMC, Isuzu, and Saab

The DuraGo BR55079 disc brake rotor is engineered to provide consistent braking performance for select Buick, Chevrolet, GMC, Isuzu, and Saab models. Designed with durable cast iron and a vented construction, this rotor supports effective heat dissipation and reliable stopping power.

  • Material: Cast iron for durability and heat resistance
  • Vented rotor design to improve cooling and reduce brake fade
  • Nominal thickness of 1.14 inches (29 mm) with discard thickness at 1.08 inches (27.5 mm)
  • Overall height of 2.13 inches (54.1 mm) and outside diameter of 12.8 inches (325 mm)
  • 6 mounting bolt holes with a 5-inch (127 mm) bolt circle diameter
  • Non-directional brake surface for versatile installation
  • Conventional rotor type without ABS tone ring

Durable Construction and Precise Fitment

The DuraGo BR55079 rotor is constructed from full cast iron, providing a solid and reliable braking surface. Its vented design enhances airflow to dissipate heat during braking, which helps maintain consistent performance and reduces the risk of rotor warping. With a nominal thickness of 1.14 inches and a discard thickness of 1.08 inches, this rotor meets OEM specifications for thickness and wear limits. The 6-bolt mounting pattern and 5-inch bolt circle diameter ensure compatibility with specific vehicle models.

Compatible Vehicles and Applications

This disc brake rotor is compatible with a range of vehicles including Buick 9-7x, Chevrolet Trailblazer, Trailblazer EXT, SSR, GMC Envoy, Envoy XL, Envoy XUV, Isuzu Ascender, Rainier, and Saab 9-7x. The DuraGo BR55079 is designed to replace original equipment rotors on these models, providing a direct fit and reliable braking performance.

  • Reduces brake noise and vibration
  • Addresses rotor wear and thickness below discard limits
  • Improves heat dissipation to prevent brake fade
  • Restores braking efficiency on vented rotor-equipped vehicles
  • Replaces warped or damaged rotors for safer stopping

Installation Notes and Tips

When installing the DuraGo BR55079 rotor, ensure the rotor surface is clean and free of any protective coatings or debris before mounting. Verify the rotor thickness is within the specified nominal and discard limits. Use proper torque specifications for the 6 mounting bolts to avoid rotor distortion. This rotor does not include an ABS tone ring, so confirm compatibility with your vehicle’s ABS system. It is recommended to replace brake pads simultaneously for optimal braking performance.

Quality Assurance and Warranty

DuraGo manufactures the BR55079 rotor to meet or exceed OEM standards for material and construction. While this rotor does not feature a rust-resistant coating, its cast iron construction provides reliable durability under normal operating conditions. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
