Centric 125.22021 Disc Brake Rotor - Rear

Centric Premium Rear Brake Rotor Overview

The Centric Premium High Carbon Alloy Disc Brake Rotor, part number 125.22021, is built for rear brake service where consistent stopping performance and noise control matter. It is a vented rotor with a smooth surface, coated hat finish, and a 5-lug pattern for direct-fit applications on select Land Rover models.

Compatible With 2020 Land Rover Defender 110 rear and 2010-2013 Land Rover Range Rover Sport rear, this rotor is engineered around high-carbon metallurgy for stable braking under repeated stops. The Centric 125 Series is a practical choice for drivers looking for OE-style fitment with improved resistance to heat-related wear.

Key Features

• Part number 125.22021 for rear brake service
• High carbon alloy construction for improved thermal stability
• Vented rotor design for rear axle applications
• Smooth friction surface for consistent pad contact
• Coated hat finish to help resist oxidation on non-friction areas
• 5 bolt holes with 120 mm bolt circle and 79 mm center hole
• Outside diameter: 365.3 mm; nominal thickness: 19.9 mm
• Discard thickness: 17.0 mm

Centric 125 Series Product Line

Centric Premium High Carbon Alloy Disc Brake Rotors use an advanced iron formulation with added molybdenum, chromium, and carbon content. That metallurgy helps reduce pad squeal with higher-friction European-style pad compounds, improves resistance to cracking during repeated stop events, and supports better oxidation resistance over time. For rear brake rotor replacement on a Land Rover Defender 110 or Range Rover Sport, the 125 Series focuses on durability and predictable pedal response.

This part cross-references Four Seasons 74005 for the same application.

What This Rotor Helps Address

• Brake noise during rear rotor and pad operation
• Heat stress from repeated braking events
• Rotor cracking concerns under higher-load use
• Surface oxidation on exposed rotor areas
• Reduced braking consistency from worn rear rotors

Installation Notes and Tips

Verify rear axle fitment by matching the 365 mm rear disc specification, bolt pattern, center hole diameter, and overall height before installation. This rotor is listed for 2020 Land Rover Defender 110 rear and 2010-2013 Land Rover Range Rover Sport rear, including Range Rover Sport applications with Brembo front calipers. Inspect pads, caliper hardware, and hub condition during service to help ensure even rotor contact and proper bedding.

Quality Assurance

Centric’s Premium High Carbon Alloy rotor line is built with corrosion-resistant metallurgy and a coated hat finish to support long-term service life in demanding brake environments. Part number 125.22021 is manufactured to meet the dimensional requirements listed for the confirmed Land Rover rear applications.
