Durable Construction and Precise Specifications

The DuraGo BR55118-01 rotor features a full cast iron construction that balances durability with effective heat management. Its vented design allows air to circulate between the rotor surfaces, reducing heat buildup and minimizing brake fade during extended use. The rotor measures 11.69 inches (297 mm) in outside diameter with an overall height of 2.07 inches (52.7 mm), ensuring proper fitment and clearance. The nominal thickness is 1.27 inches (32.3 mm), with a discard thickness of 1.21 inches (30.7 mm), indicating when replacement is necessary to maintain braking safety. This rotor includes six mounting bolt holes with a 4.53 inch (115 mm) bolt circle diameter and a center hole diameter of 2.78 inches (70.7 mm), matching factory specifications for the supported vehicle models.

Compatible Vehicles and Applications

• Designed for Buick Montana and Terraza models
• Compatible with Chevrolet Uplander and Relay vehicles
• Fits select Pontiac and Saturn models requiring a 6-bolt vented rotor
• Ideal for replacing worn or damaged rotors to restore braking performance
• Suitable for vehicles with conventional, non-directional brake rotors

Installation Notes and Tips

When installing the DuraGo BR55118-01 rotor, ensure the rotor surface is clean and free of debris before mounting. Verify that the mounting bolt holes align correctly with the vehicle hub assembly. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system if applicable. Use proper torque specifications for mounting bolts to avoid rotor warping or uneven wear. It is recommended to replace brake pads simultaneously to optimize braking efficiency and rotor lifespan.
