Product Details

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on corrosion protection across the rotor surfaces and hat area, making it a practical choice for rear brake replacement on older SUV and truck platforms. This rotor measures 80.2 mm overall height, uses a floating/DIH disc mounting configuration, and includes one miscellaneous hole as specified by the manufacturer. The 320.43015F is sized for rear fitment on vehicles such as the Isuzu Trooper, Isuzu Rodeo, and Honda Passport, where correct diameter, thickness, and lug pattern are critical for proper brake service.

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

Common Problems This Rotor Can Address

• Rear brake pulsation from rotor wear or thickness variation
• Corrosion on the rotor hat or braking surfaces
• Reduced braking performance from a worn rear rotor
• Noise caused by uneven or damaged rotor surfaces
• Service replacement for vehicles requiring the specified 313.5 mm rear rotor

Installation Notes and Tips

Verify rear fitment by matching the vehicle year, make, model, and lug pattern before installation. Confirm rotor thickness, center hole diameter, and overall height against the existing part to ensure proper fit on the hub and brake assembly. For best results, inspect pads, caliper hardware, and hub surfaces during rotor replacement, and clean mating surfaces before mounting the new rotor.

Quality Assurance

Centric GCX Elemental Protection rotors are built with coated surfaces to help resist corrosion in service. Part number 320.43015F is manufactured to the listed dimensional specifications for the confirmed rear applications shown above.
