Product Details

Centric GCX Elemental Protection Disc Brake Rotors - Full Coating are designed around vehicle-specific metallurgy and coating coverage to match OE-style brake system requirements. The RS200 finish is applied to non-mating surfaces to help protect the rotor from rust while maintaining the friction surfaces needed for braking performance. This makes 320.36003F a practical choice for front brake service on 2011-2015 Chevrolet Spark, 2018-2020 Chevrolet Beat, and other listed Chevrolet and Pontiac applications.

This rotor is also listed for 1994-2012 Chevrolet Chevy, 2003 Chevrolet Chevy Monza, 1999-2003 Chevrolet Chevy Pickup, 1990-1993 Pontiac LeMans, and 1988-1989 Pontiac LeMans front positions. The GCX Full Coating line is built for broad vehicle coverage, and this part number is one of the front rotor options used across those applications.

Common Problems This Rotor Can Address

• Front brake rotor rust on exposed surfaces
• Brake pulsation caused by worn or below-spec rotors
• Reduced braking consistency from rotor wear
• Corrosion buildup on hat and non-mating surfaces
• Replacement needs for OE-style front disc brake service

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and brake pad condition before installation. Clean the hub mounting surface thoroughly so the floating mount seats evenly, and confirm the rotor meets the vehicle’s front application requirements for Chevrolet Spark, Chevrolet Beat, Chevrolet Chevy, Chevrolet Chevy Monza, Chevrolet Chevy Pickup, or Pontiac LeMans. If the existing braking system shows uneven wear, inspect pads and related hardware during rotor replacement.
