Centric 320.34137H Disc Brake Rotor - Rear

Centric GCX Rear Disc Brake Rotor

Centric GCX Elemental Protection Disc Brake Rotors are built to match OE performance while adding full-surface corrosion protection. This rear rotor for the Mini Cooper Countryman and Mini Cooper Paceman uses a fully coated finish and high carbon metallurgy for consistent braking and long-term appearance.

The Centric GCX product line focuses on application-specific coating patterns and rotor metallurgy. For this application, that means a rotor engineered around the vehicle’s OEM-style material profile, with coated non-mating surfaces to help resist rust on the hat and outer surfaces.

• Part number 320.34137H
• Fully coated disc finish with coated hat for rust and corrosion resistance
• High carbon rotor metallurgy for OE-style performance characteristics
• Solid rotor design with smooth surface type
• Rear brake rotor for Mini Cooper Countryman and Mini Cooper Paceman applications
• 5-lug pattern with 120 mm bolt circle diameter
• Outside diameter: 279.7 mm (11.012 in)
• Nominal thickness: 10.0 mm; discard thickness: 8.4 mm

Centric 320.34137H is a rear disc brake rotor for 2011-2016 Mini Cooper Countryman and 2013-2016 Mini Cooper Paceman applications. It is designed for drivers replacing a worn or rusted rear rotor on a Mini Cooper Countryman or Mini Cooper Paceman and wanting a direct-fit rotor with coated non-friction surfaces. The floating disc mounting, 79.0 mm center hole diameter, and 147.6 mm hat ID support proper fitment for the listed rear applications.

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

Common Replacement Reasons

• Rear brake pulsation from rotor wear or thickness variation
• Surface rust on the hat or outer rotor surfaces
• Noise caused by uneven rotor finish or corrosion buildup
• Reduced braking consistency from a worn rear disc brake rotor
• Replacement for a Mini Cooper Countryman or Mini Cooper Paceman rear brake service

Installation Notes

Verify rotor dimensions, hub fit, and rear position before installation. Clean the hub mounting surface thoroughly so the coated rotor seats flat and runs true. Follow the vehicle manufacturer’s brake service procedure, including proper torque on wheel fasteners and a complete brake inspection after installation.

Quality Assurance

Centric GCX rotors are engineered to align with OE performance targets and use advanced RS200 coating on non-mating surfaces for added protection against rust and corrosion. The GCX line is built with application-specific coating patterns and high carbon alloy formulations to match the vehicle’s original metallurgy profile.
