Centric 320.62056F Disc Brake Rotor - Front

Centric GCX Front Brake Rotor Overview

The Centric GCX Elemental Protection Disc Brake Rotor, part number 320.62056F, is a front vented rotor with a fully coated disc finish and coated hat finish for corrosion resistance. It measures 278.0 mm outside diameter, 26.0 mm nominal thickness, and 24.7 mm discard thickness, making it a direct-fit replacement for select Chevrolet, Pontiac, and Oldsmobile front brake applications.

Built with a smooth surface, straight vane design, floating disc mounting, and a 5-lug bolt pattern, this rotor supports consistent braking performance on vehicles such as the Chevrolet Malibu, Pontiac Grand Am, and Oldsmobile Alero. The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on protection against environmental exposure while maintaining OE-style fitment.

Detailed Product Description

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line is engineered for drivers who need a front rotor replacement with corrosion-resistant surface treatment and OE-style dimensions. Part number 320.62056F uses a fully coated disc and coated hat to help protect exposed metal surfaces, while the vented, straight-vane design supports heat management during repeated stops. This rotor is a fitment match for 1997-2003 Chevrolet Malibu front, 1999-2005 Pontiac Grand Am front, 1999-2004 Oldsmobile Alero front, 1997-1999 Oldsmobile Cutlass front, and 2004-2005 Chevrolet Classic front applications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Rotor Helps Address

• Front brake pulsation from worn or uneven rotor surfaces
• Corrosion on exposed rotor and hat surfaces
• Brake noise caused by rotor wear or surface irregularity
• Reduced braking consistency from rotor thickness loss
• Fitment issues when replacing a worn OE-style front rotor

Installation Notes and Tips

Verify rotor dimensions, hub center diameter, bolt circle, and 5-lug pattern before installation. Clean the hub mounting surface thoroughly to help prevent runout-related brake pulsation. Because this rotor is vented and floating-mounted, it should be installed on the front axle only for the listed Chevrolet Malibu, Pontiac Grand Am, Oldsmobile Alero, Oldsmobile Cutlass, and Chevrolet Classic applications. Always inspect pads, calipers, and hardware condition during rotor replacement.

Quality Assurance

Centric GCX rotors are built to match the listed dimensions and fitment requirements for the specified vehicles. Part number 320.62056F is specified for front brake applications on 1997-2005 Chevrolet, Pontiac, and Oldsmobile models listed above.
