Detailed Product Description

This Power Stop rotor features a vented disc design that enhances heat dissipation during braking, reducing the risk of brake fade. The Geomet coating provides a protective layer against rust and corrosion, extending the rotor's service life especially in environments prone to moisture exposure. With a nominal thickness of 1.26 inches (32.00 mm) and a discard thickness of 1.18 inches (30.00 mm), this rotor meets precise wear limits to maintain safe braking performance. The 12.60-inch (320.00 mm) outside diameter and 5-lug hole pattern with a 4.70-inch (120.00 mm) bolt circle diameter ensure compatibility with the front brake assembly of Pontiac GTO models.

The Power Stop - Front Genuine Geomet Coated Rotor line is designed to provide a balance of durability and corrosion resistance. This product line focuses on delivering rotors that maintain structural integrity and braking efficiency over time, making it suitable for drivers seeking dependable replacement parts for their Pontiac GTO.

Common Applications and Problem Solving

• Replacement for worn or warped front disc brake rotors on Pontiac GTO
• Addresses brake noise caused by rust or uneven rotor surfaces
• Improves braking consistency by reducing heat-related fade
• Prevents premature rotor corrosion in humid or wet conditions
• Restores proper rotor thickness to maintain braking safety

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is within the nominal range and above the discard thickness limit. Use proper torque specifications for the 5-lug mounting pattern with a 4.70-inch bolt circle diameter. It is recommended to inspect brake pads and hardware during rotor replacement to ensure optimal braking system performance.
