Detailed Product Description

This Centric GCX Elemental Protection Disc Brake Rotor is specifically designed for use on Ford Explorer, Explorer Sport Trac, and Mercury Mountaineer vehicles. The rotor features a fully coated disc and hat finish that helps prevent rust and corrosion, extending the service life of the brake component. Its vented design with straight vanes promotes efficient heat dissipation, reducing the risk of brake fade during heavy braking. The rotor’s nominal thickness of 1.181 inches (30.000 mm) ensures structural integrity, while the discard thickness of 1.122 inches (28.500 mm) indicates the minimum safe thickness for replacement. The smooth surface finish supports consistent pad contact and braking performance. The floating disc mounting system allows for slight movement to accommodate thermal expansion and improve rotor longevity.
