Centric 125.34079 Disc Brake Rotor - Front

Centric Premium High Carbon Alloy Rotor Overview

The Centric Premium High Carbon Alloy Disc Brake Rotor, part number 125.34079, is built for front brake applications that demand stable stopping performance and consistent pedal feel. It is a vented, smooth-surface rotor with a coated hat finish, sized for 330 mm front disc applications on select BMW models.

Compatible With BMW X1, BMW 130i, BMW 330i, and BMW 330xi front brake fitments, this rotor uses a high-carbon alloy metallurgy to help reduce brake noise and improve resistance to cracking during repeated stops. The Centric 125 Series is also formulated to better resist oxidation, which supports long-term service life in demanding driving conditions.

Key Features

Product Line Details

Centric Premium High Carbon Alloy Disc Brake Rotors are part of the Centric 125 Series, a rotor line focused on metallurgy and dimensional stability. The higher carbon content helps improve friction characteristics, while the alloy blend is engineered to better handle repeated stop-and-go use and higher-friction European brake pad compounds.

Detailed Description

Centric 125.34079 is a front brake rotor with an overall height of 73.2 mm, nominal thickness of 23.9 mm, and discard thickness of 22.4 mm. It features straight vanes, a floating disc mounting design, and a 14.7 mm stud/lug hole diameter. This rotor is a direct-fit option for 2010-2014 BMW X1 front applications including xDrive 23d and xDrive 28i, plus 2012 BMW X1 Europe front, 2006-2010 BMW 130i front, and 2006 BMW 330i and 330xi front.

This part cross-references Raybestos Brakes 980484 for the same application.

Common Issues This Rotor Can Address

• Brake squeal during everyday or higher-friction pad use
• Rotor cracking from repeated hard stops
• Reduced braking consistency under heat
• Surface oxidation on exposed rotor areas
• Uneven brake feel from worn front rotors

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and brake pad condition before installation. Clean the hub mounting surface thoroughly to help prevent rotor runout, and confirm the rotor matches the vehicle’s front brake configuration. For best results, replace pads that are worn, glazed, or unevenly worn when servicing the rotor.

Quality Assurance

Centric’s high-carbon alloy rotor construction is engineered for dimensional stability, noise control, and improved resistance to cracking and oxidation in demanding front brake service.
