Product Details

Centric’s GCX Elemental Protection Disc Brake Rotors are application-specific, with coating patterns and metallurgy selected to align with OEM brake pad friction and vehicle requirements. This rotor uses Centric’s RS200 finish on non-mating surfaces to help resist rust and corrosion, while the smooth braking surface supports consistent pad contact. The GCX line also uses high-carbon metallurgy profiles matched to the vehicle application, helping maintain OE-style fit and braking characteristics. Part number 320.62087F is a direct-fit front rotor for 2005 Buick LeSabre, 2005 Buick Park Avenue, 2005 Cadillac DeVille, 2005 Chevrolet Impala, 2005 Chevrolet Monte Carlo, and 2005 Pontiac Bonneville front brake service.

Common Reasons to Replace

• Brake pulsation or steering wheel shake during stops
• Rotor rust on exposed surfaces
• Uneven pad contact or braking noise
• Reduced braking smoothness from worn rotor thickness
• Front brake service on a 2005 Buick LeSabre, Cadillac DeVille, Chevrolet Impala, or Pontiac Bonneville

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and brake pad condition before installation. This rotor is for front applications only and uses a floating disc mounting design with a straight-vane vented construction. Clean the rotor surface before installation and follow the vehicle manufacturer’s brake service procedures for proper bedding and torque sequence. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Centric GCX rotors are engineered to match OE performance targets and use corrosion-protective coatings on non-mating surfaces for long-term appearance and durability. Part number 320.62087F is built to Centric’s application-specific rotor standards for the listed 2005 Buick, Cadillac, Chevrolet, and Pontiac front brake applications.
