Product Details

Centric GCX rotors are designed to match OE performance while adding protection on exposed surfaces. The full coating helps resist rust on the hat and non-mating areas, while the rotor metallurgy is selected to align with OEM-style vehicle requirements. This makes 320.63057F a practical choice for Chrysler Pacifica rear brake rotor replacement when you want a clean finish and consistent fitment.

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

Common Reasons to Replace

• Rear brake pulsation or vibration during stopping
• Visible rust or corrosion on the rotor surface or hat
• Brake noise caused by uneven rotor wear
• Reduced braking consistency from worn rotor thickness
• Service replacement for a 2004-2008 Chrysler Pacifica rear brake rotor

Installation Notes

Verify rotor dimensions, hub fit, and rear position before installation. Clean the hub mounting surface thoroughly to help prevent runout-related brake noise or pedal pulsation. Always inspect brake pads, caliper hardware, and wheel bearings during rotor service, and follow the vehicle manufacturer’s torque specifications.
