Product Line Details: Centric GCX Elemental Protection

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, especially in harsh weather conditions or environments prone to moisture and road salt. The rotors maintain structural integrity and braking performance while minimizing surface degradation over time.

Technical Specifications and Compatibility

This disc brake rotor features a vented design with straight vanes to optimize airflow and heat dissipation during braking. The nominal thickness of 0.787 inches (20 mm) and discard thickness of 0.728 inches (18.5 mm) ensure the rotor can be resurfaced within safe limits. The rotor’s outside diameter measures 12.795 inches (325 mm), and the overall height is 3.358 inches (85.3 mm). The hat and disc are fully coated to protect against corrosion, and the smooth surface finish supports consistent pad contact.

Compatible with a range of Chevrolet and GMC vehicles, including the Astro, Avalanche 1500, Safari, Sierra 1500 (Classic and HD), Silverado 1500 (Classic and HD), Suburban 1500, Tahoe, Yukon, and Yukon XL 1500, this rotor is designed to meet OEM specifications for these models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Upgrading corroded rotors to improve braking reliability
• Addressing rotor thickness below manufacturer discard limits
• Reducing brake noise and vibration from uneven rotor surfaces
• Maintaining braking performance in vehicles exposed to harsh environments

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean hub surface to prevent rotor runout
• Torque lug nuts to manufacturer specifications for proper fitment
• Check compatibility with ABS systems; this rotor does not include an ABS tone ring
• Inspect brake pads and replace if worn to ensure optimal rotor performance
