Product Line Details: Centric GCX Elemental Protection Disc Brake Rotors - Full Coating

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line is designed to provide enhanced elemental protection through a complete coating process on both the rotor disc and hat. This full coating helps prevent corrosion and extends rotor life, especially in environments prone to moisture and road salt exposure. The rotors maintain precise dimensions and feature a vented design with straight vanes to optimize cooling and braking efficiency.

Technical Specifications and Features

This disc brake rotor is vented with straight vanes to facilitate effective heat dissipation during braking, reducing the risk of brake fade. The floating disc mounting system allows for slight movement between the rotor and hub, minimizing stress and improving rotor longevity. The rotor’s nominal thickness is 1.252 inches (31.8 mm), with a discard thickness of 1.142 inches (29.0 mm), ensuring clear service limits for safe operation. The smooth surface finish promotes even brake pad wear and consistent braking performance.
