Detailed Product Description

The DuraGo BR55125 rotor is constructed from full cast iron, providing a solid and durable braking surface suitable for daily driving conditions. Its solid rotor design without slots or cross-drilling ensures even wear and straightforward maintenance. The drum-in-hat configuration integrates a parking brake drum, making it compatible with vehicles equipped with rear drum parking brakes. This rotor is non-directional, allowing for flexible installation without concern for rotor orientation.

With an outside diameter of 10.94 inches and a nominal thickness of 0.44 inches, this rotor meets OEM specifications for the Buick Allure, LaCrosse, and Chevrolet Impala and Monte Carlo models. The mounting bolt pattern includes five holes spaced on a 4.53-inch bolt circle diameter, ensuring proper fitment and secure attachment. Note that this rotor does not include an ABS tone ring and does not feature a rust-resistant coating, so regular inspection and maintenance are recommended to prevent corrosion.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation or noise
• Addressing rotor thickness below discard limits to maintain safe braking
• Resolving uneven brake pad wear due to rotor surface irregularities
• Upgrading to OEM-spec rotors for consistent braking performance on Buick Allure and Chevrolet Impala
• Ensuring compatibility with drum-in-hat parking brake systems on select models

Installation Notes and Tips

• Verify rotor dimensions and bolt pattern against vehicle specifications before installation
• Inspect brake pads and hardware for wear and replace as necessary during rotor replacement
• Clean rotor mounting surface to ensure proper fit and prevent vibration
• Torque mounting bolts to manufacturer specifications to avoid rotor warping
• Check for ABS sensor compatibility since this rotor does not include a tone ring
