• Vented rotor design to improve cooling and reduce brake fade
• Nominal thickness of 1.18 inches (30 mm) with discard thickness at 1.06 inches (27 mm)
• Overall height of 2.04 inches (51.9 mm) and outside diameter of 10.83 inches (275 mm)
• Five mounting bolt holes with a 4.53 inch (115 mm) bolt circle diameter
• Non-directional brake surface for versatile installation
• Conventional rotor type without ABS tone ring

Detailed Product Description

The DuraGo BR55070 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, helping to dissipate heat generated during braking and reducing the risk of brake fade. The rotor measures 10.83 inches in outside diameter and features a nominal thickness of 1.18 inches, with a discard thickness of 1.06 inches, indicating when replacement is necessary to maintain safe braking performance.

With five mounting bolt holes spaced on a 4.53 inch bolt circle diameter, this rotor is designed for direct compatibility with the front braking systems of Buick Rendezvous and Pontiac Aztek vehicles. The non-directional brake surface allows for flexible installation without concern for rotor orientation. This rotor does not include an ABS tone ring and is intended for use in conventional braking setups.

Compatible Vehicles and Applications

• Buick Rendezvous front disc brake replacement
• Pontiac Aztek front brake rotor upgrade
• Replacement rotor for vehicles requiring a 10.83 inch diameter vented rotor
• Suitable for models with 5-bolt mounting patterns and 4.53 inch bolt circle diameter

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (1.06 inches) before installation
• Clean rotor mounting surface and hub to prevent uneven wear or noise
• Use proper torque specifications for the 5 mounting bolts to avoid warping
• Check brake pads for wear and replace if necessary when installing new rotors
• Perform a bed-in procedure after installation to optimize braking performance
