Product Details

Centric GCX Elemental Protection Disc Brake Rotors are designed to match OE performance while adding protection against rust and corrosion on exposed surfaces. The GCX FC full-coating design uses Centric’s RS200 finish on non-mating areas, helping preserve the rotor’s appearance and durability over time. Centric also uses application-specific coating patterns and metallurgy to align the rotor with the vehicle’s original brake system requirements.

It is a direct-fit style replacement for drivers searching for a rear brake rotor for Chrysler Town & Country, Dodge Caravan rear rotor replacement, or Dodge Grand Caravan rear brake rotor applications.

Common Problems This Rotor Can Address

• Rear rotor rust on exposed surfaces
• Brake pulsation caused by worn rotor thickness
• Uneven braking feel from rotor wear
• Surface corrosion that affects appearance and service life
• Replacement needs for OE-style rear brake service

Installation Notes

Verify rotor dimensions, hub fitment, and rear axle application before installation. Clean the hub mounting surface thoroughly to help prevent runout-related brake noise or pedal vibration. Inspect pads, calipers, and hardware condition during service so the new rotor can seat properly. This rotor is for rear position use only on the listed vehicles.

Quality Assurance

Centric designs the GCX rotor line around OE performance targets and vehicle-specific metallurgy. The full coating and RS200 surface protection are intended to help resist rust and corrosion on non-mating surfaces throughout normal service.
