Detailed Product Description

The DuraGo BR55036 is a full cast iron disc brake rotor designed specifically for compatibility with various Buick, Oldsmobile, and Pontiac models including the Buick Century, LeSabre, and Regal, Oldsmobile 88 and Intrigue, and Pontiac Bonneville, Grand Prix, and Montana. Its vented construction enhances heat dissipation during braking, reducing the risk of brake fade under normal driving conditions. The rotor features a conventional, non-directional braking surface that allows for flexible installation without concern for rotor orientation. With a nominal thickness of 1.27 inches and a discard thickness of 1.21 inches, this rotor provides a clear service life indicator to maintain safe braking performance. The five mounting bolt holes with a 4.65 inch bolt circle diameter ensure proper fitment and secure attachment to the vehicle hub.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thickness below discard limits
• Eliminating noise and vibration from uneven rotor surfaces
• Upgrading from solid to vented rotors for improved heat management
• Restoring proper rotor dimensions for safe brake pad contact

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum discard specifications
• Clean rotor mounting surface and hub to prevent runout and vibration
• Use proper torque specifications on mounting bolts to avoid rotor distortion
• Inspect brake pads and replace if worn to ensure optimal rotor performance
• Check for ABS tone ring compatibility; this rotor does not include an ABS tone ring
