This part cross-references Centric Parts (e.g., 120.51006, 121.51006) for the same application.

What It Helps Address

• Rear brake pulsation caused by rotor wear or uneven surfaces
• Corrosion on the rotor hat and non-braking areas
• Reduced braking consistency from a worn rear rotor
• Noise or vibration during rear brake service
• Replacement needs for a damaged or below-spec rear disc rotor

Installation Notes and Tips

Verify rear axle fitment by matching the vehicle year, make, model, and the 258 mm rotor diameter requirement before installation. Confirm the 4-stud wheel configuration noted in the fitment data for the listed Kia and Hyundai applications. Inspect pads, caliper condition, and hub surfaces during service, and clean the rotor and mating surfaces before installation to support proper seating.

For best results, pair the rotor with matching Wagner brake pads and follow the vehicle manufacturer’s brake service procedures. The BD125609E is a rear rotor only and should be installed on the applications listed in the fitment data.

Quality Assurance

Wagner Brake premium rotors are built with a focus on performance, corrosion resistance, and straightforward installation. The BD125609E reflects that approach with a cast iron full cast design and protective coating on non-braking surfaces for dependable brake service.
