Product Line Details

Centric GCX Elemental Protection rotors are application-specific, with coating patterns and metallurgy selected to align with brake pad friction type and OE rotor requirements. The GCX line uses Centric’s RS200 finish on non-mating surfaces to help maintain appearance and reduce corrosion over time. Part number 320.35043H follows that approach for rear brake service on Mercedes-Benz ML-Class vehicles.

Detailed Description

This Centric GCX rotor is a rear disc brake rotor for 2002-2005 Mercedes-Benz ML500, 2000-2003 Mercedes-Benz ML55 AMG, and 2000-2001 Mercedes-Benz ML430 models. The rotor measures 13.051 inches in outside diameter, 2.173 inches in overall height, and 18.230 lbs, with a smooth surface and solid construction. Its fully coated finish helps protect non-mating surfaces from rust and corrosion, while the high-carbon alloy supports consistent thermal behavior in demanding stop-and-go driving. If you are searching for a rear brake rotor for Mercedes-Benz ML500 2002-2005 or a rear rotor for Mercedes-Benz ML55 AMG 2000-2003, 320.35043H is the direct fitment reference.

Common Reasons for Replacement

• Brake pulsation from rotor wear or thickness variation
• Rust buildup on exposed rotor surfaces
• Reduced braking smoothness during rear brake service
• Rotor scoring or surface damage
• Noise caused by worn or uneven rear rotors

Installation Notes and Tips

• Verify rear axle fitment against the vehicle’s brake package before installation.
• Inspect pads, calipers, and hub surfaces before mounting the new rotor.
• Clean the rotor’s friction surfaces before service to remove protective residue.
• Torque wheel fasteners to the vehicle manufacturer’s specification.
• Bed in new pads and rotors according to the brake pad manufacturer’s procedure.

Quality Assurance

Centric designs the GCX rotor line to match OE performance targets and uses metallurgical formulations intended to align with OEM rotor profiles. Part number 320.35043H is engineered for consistent rear brake service on the listed Mercedes-Benz ML-Class applications.
