• Full cast design ensures structural integrity and longevity
• Rust-resistant coating protects against corrosion and extends rotor life
• Solid rotor type with a non-directional brake surface for versatile installation
• Compatible with 5 mounting bolt holes and conventional drum-in-hat design
• Outside diameter of 11.06 inches (280.8 mm) fits specific Buick and Oldsmobile models
• Nominal thickness of 0.43 inches (11 mm) with discard thickness at 0.35 inches (9 mm)
• Overall height measures 1.53 inches (38.8 mm) for proper fitment

Technical Details and Construction

The DuraGo BR55065-01 rotor is made from cast iron, a material known for its excellent heat absorption and durability under braking stress. This rotor features a full cast construction, which enhances its strength and resistance to warping. The rust-resistant coating helps prevent corrosion, maintaining rotor integrity over time, especially in environments prone to moisture and road salt.

With a solid rotor design and a non-directional brake surface, this part allows for flexible installation without concern for rotor orientation. The rotor includes five mounting bolt holes arranged on a 4.65-inch (118 mm) bolt circle diameter, ensuring compatibility with the specified Buick and Oldsmobile models. The conventional drum-in-hat type rotor design is standard for these vehicles, providing straightforward replacement without modification.

Compatible Vehicles and Applications

• Buick LeSabre
• Oldsmobile Aurora
• Oldsmobile Park Avenue

This rotor is intended for use in disc brake systems on the front or rear axle, depending on vehicle specifications. It addresses common braking issues such as uneven rotor wear, vibration during braking, and reduced stopping efficiency caused by worn or damaged rotors.

• Eliminates brake pulsation and vibration
• Restores smooth and consistent braking performance
• Prevents rotor warping and premature wear
• Reduces noise caused by rotor surface irregularities
• Improves overall brake system reliability

Installation Notes and Tips

When installing the DuraGo BR55065-01 rotor, ensure the mounting surface is clean and free of debris to promote proper rotor seating. Verify that the rotor thickness meets the nominal specifications and does not fall below the discard thickness of 0.35 inches (9 mm) to maintain safe braking performance. Use appropriate torque settings for the mounting bolts to avoid rotor distortion. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system before installation.
