Product Line Details

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on providing rotors with a complete protective coating to resist rust and corrosion. This full coating extends the rotor’s service life and maintains consistent braking performance, especially in environments prone to moisture and road salt exposure. The rotors feature a vented design with pillar-style vanes to optimize cooling and reduce brake fade during operation.

Technical Specifications and Features

This disc brake rotor features a nominal thickness of 1.024 inches (26.000 mm) and a discard thickness of 0.906 inches (23.000 mm), ensuring it meets OEM standards for safe replacement. The rotor’s outside diameter measures 11.654 inches (296.000 mm), with an overall height of 1.713 inches (43.500 mm). The floating disc mounting system allows for slight movement to reduce stress and improve rotor longevity. The smooth surface finish supports consistent pad contact and braking efficiency. The rotor is vented with pillar-style vanes to enhance heat dissipation, which helps maintain braking performance under demanding conditions.

Compatible Vehicles and Applications

• Chevrolet Aura, Cobalt, Malibu, HHR
• Pontiac G4, G5, G6, Pursuit
• Saturn Ion

This rotor is designed specifically for these models, ensuring proper fitment and performance when replacing worn or damaged rotors.

Common Issues Addressed by This Rotor

• Brake rotor corrosion and rust buildup
• Uneven rotor wear causing brake pulsation
• Overheating and brake fade during extended use

• Reduced braking efficiency due to worn rotor thickness

Installation Notes and Tips

When installing the Centric GCX Elemental Protection Disc Brake Rotor 320.62078F, ensure the rotor thickness is above the discard thickness of 0.906 inches (23.000 mm). Clean the hub surface before mounting to prevent runout. Use proper torque specifications on the five lug bolts (0.563 inch diameter) to secure the rotor. Since bearings and ABS tone rings are not included, verify compatibility with your vehicle’s existing components. The floating disc mounting requires careful alignment to avoid uneven wear.
