Centric 320.35037H Disc Brake Rotor - Rear

Centric GCX Rear Brake Rotor Overview

Centric GCX Elemental Protection Disc Brake Rotor 320.35037H is a rear replacement rotor built for OE-style braking performance and corrosion resistance. It is fully coated on non-mating surfaces, uses a smooth solid rotor design, and matches the fitment requirements for select Mercedes-Benz ML-Class applications.

Compatible With 1998-2005 Mercedes-Benz ML320, ML430, and ML350 rear brake applications, this rotor is built around Centric’s GCX Elemental Protection line for drivers who want a direct-fit rear disc brake rotor with coated surfaces and application-specific metallurgy.

Product Line Details

Centric GCX Elemental Protection rotors are engineered to match OE performance while adding rust and corrosion protection on exposed surfaces. The GCX line uses application-specific coating patterns and high-carbon metallurgy to align with the brake pad friction type and the vehicle’s original rotor profile. This helps maintain proper braking feel and long-term appearance on daily-driven vehicles.

Detailed Description

Centric 320.35037H is a rear brake rotor for 1998-2003 Mercedes-Benz ML320, 1998-1999 Mercedes-Benz ML430, and 2003-2005 Mercedes-Benz ML350 models. The rotor measures 285 mm in outside diameter, 55.600 mm in overall height, and 184.000 mm in nominal drum diameter, with a floating/DIH mounting style and one miscellaneous hole as specified by Centric. The fully coated finish helps protect non-mating surfaces from rust, while the high-carbon GCX metallurgy supports OE-matched performance and thermal stability.

This rotor is a direct-fit choice for Mercedes-Benz ML320 rear brake rotor replacement, Mercedes-Benz ML430 rear disc brake service, and Mercedes-Benz ML350 rear brake maintenance. Part number 320.35037H is also useful when searching for a Centric GCX rear rotor with coated surfaces and OE-style dimensions.

Common Problems This Rotor Addresses

• Rear rotor rust on exposed surfaces
• Brake pulsation caused by worn or below-spec rotors
• Uneven pad contact from surface wear
• Noisy braking from rotor surface deterioration
• Loss of braking consistency during routine service

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and rear-position fitment before installation. Clean the hub mounting surface thoroughly so the rotor seats flat, and inspect pads, calipers, and hardware condition during brake service. Because this rotor is solid and application-specific, confirm it matches the vehicle’s rear brake configuration before ordering. Part number 320.35037H should be matched to the exact year, model, and rear position listed above.

Quality Assurance

Centric designs the GCX line to align with OE performance targets and vehicle-specific metallurgy requirements. The coated finish on non-mating surfaces is intended to improve corrosion resistance and preserve rotor appearance over time.
