Detailed Product Description

The DuraGo BR900512 disc brake rotor is constructed from full cast iron, providing the necessary strength and thermal capacity for consistent braking on the Pontiac G8. Its vented design allows air to flow between the rotor surfaces, helping to reduce heat buildup during braking and maintain performance under demanding conditions. The drum-in-hat construction integrates a parking brake drum within the rotor, making it compatible with vehicles equipped with drum-in-hat parking brake systems.

With a nominal thickness of 0.87 inches (22 mm) and a discard thickness of 0.79 inches (20 mm), this rotor meets the specifications required for safe and effective braking. The 5 mounting bolt holes and precise center hole diameter ensure a secure fit on the Pontiac G8 hub assembly. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation or noise
• Addressing rotor thickness below manufacturer discard limits
• Resolving overheating issues due to insufficient rotor ventilation
• Upgrading to a rotor compatible with drum-in-hat parking brake systems
• Ensuring proper fitment for Pontiac G8 brake system maintenance

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum specifications
• Clean mounting surfaces to prevent rotor runout and vibration
• Torque mounting bolts to manufacturer specifications for secure fitment
• Inspect brake pads and hardware during rotor replacement for optimal performance
• Perform a proper bed-in procedure after installation to maximize rotor and pad life
