Centric 320.34131H Disc Brake Rotor - Rear

Centric GCX Rear Brake Rotor Overview

The Centric GCX Elemental Protection Disc Brake Rotor, part number 320.34131H, is a rear vented rotor built for OE-style braking performance and corrosion resistance. It is a fitment-based replacement for select BMW 5 Series applications, including BMW 528i, 528i xDrive, 535i, 535i xDrive, 535d, 535d xDrive, and ActiveHybrid 5 rear brake service.

With a fully coated disc finish, coated hat, and high-carbon rotor metallurgy, this rotor is engineered for consistent braking feel and long-term surface protection on daily-driven vehicles.

Key Features

• Part number 320.34131H rear disc brake rotor
• Fully coated disc finish with coated hat for rust and corrosion resistance
• High-carbon rotor construction for OE-style thermal stability
• Vented rotor design with smooth surface type
• 330 mm outside diameter, 20.0 mm nominal thickness, 18.4 mm discard thickness

Product Line Details

Centric GCX Elemental Protection Disc Brake Rotors are built around application-specific coating patterns and metallurgy. The GCX line uses Centric’s RS200 finish on non-mating surfaces and high-carbon alloy formulations selected to align with OEM rotor profiles, helping maintain fit, finish, and braking consistency across covered applications.

Detailed Description

Centric 320.34131H is a rear brake rotor for BMW 528i rear brake replacement, BMW 528i xDrive rear brake service, and other listed BMW 5 Series rear applications. The rotor measures 330 mm in outside diameter, 69.1 mm in overall height, and uses a floating/DIH disc mounting configuration with one miscellaneous hole. Its fully coated construction helps protect exposed surfaces from rust while the smooth friction surface supports predictable pad contact.

This rotor is a direct-fit option for drivers searching for a rear brake rotor for 2011-2016 BMW 528i, rear brake rotor for 2012-2016 BMW 528i xDrive, or rear brake rotor for 2014-2016 BMW 535i and 535d models. Part number 320.34131H is also listed for 2012-2016 BMW ActiveHybrid 5 rear applications.

Common Issues This Rotor Can Address

• Rear rotor rust on coated and uncoated braking surfaces
• Brake pulsation caused by worn or below-spec rotor thickness
• Uneven pad contact from surface wear or corrosion buildup
• Noise associated with rotor surface deterioration
• Loss of braking consistency from heat-stressed rear rotors

Installation Notes and Tips

Verify rotor diameter, thickness, center bore, and bolt pattern before installation. This rotor is for rear position use only and is listed for BMW models with standard front brakes in the applicable notes. Inspect pads, calipers, and hub surfaces during service, and confirm the rotor meets the vehicle’s rear brake specification before assembly.

Compatible fitment includes 2011-2016 BMW 528i rear, 2012-2016 BMW 528i xDrive rear, 2014-2016 BMW 535d rear, 2014-2016 BMW 535d xDrive rear, 2014-2016 BMW 535i rear, 2011-2016 BMW 535i xDrive rear, and 2012-2016 BMW ActiveHybrid 5 rear. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Centric designs GCX rotors to match OE performance targets while improving protection against rust and corrosion through coated non-mating surfaces and application-specific metallurgy. The GCX platform is supported by a broad catalog covering a large share of late-model vehicles on the road.
