Product Details

Centric’s GCX Elemental Protection rotor line is application-specific, using coating patterns and metallurgy selected to align with brake pad friction type and vehicle OEM requirements. This rotor uses Centric’s RS200-style coating on non-mating surfaces to help protect against rust while maintaining the braking surface needed for consistent contact. The high carbon construction supports thermal stability and is suited to front brake service on the Mercedes-Benz ML320, ML350, and ML430. Part number 320.35036H is a direct-fit replacement for the listed front positions.

Common Brake Issues This Rotor Can Address

• Surface rust on exposed rotor areas
• Brake pulsation caused by worn or uneven front rotors
• Noisy braking from degraded rotor surfaces
• Reduced braking consistency from rotor wear beyond discard thickness
• Premature cosmetic corrosion on the hat and outer surfaces

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and lug pattern before installation. Clean the hub mounting surface thoroughly to reduce runout concerns, and inspect pads, calipers, and hardware condition during rotor replacement. Because this rotor is vented and application-specific, confirm it is being installed in the front position on the listed Mercedes-Benz ML320, ML350, or ML430 before service. Part number 320.35036H should be matched to the vehicle’s brake configuration using the fitment data provided.

Quality Assurance

Centric designs the GCX rotor line to match OE performance targets while improving protection from rust and corrosion. The brand’s application-specific metallurgy and coating strategy are intended to deliver consistent fit and finish across the listed Mercedes-Benz front brake applications.
