Detailed Description

Wagner Brake BD126457E is engineered as a rear replacement rotor for vehicles including the Chevrolet Tahoe, GMC Yukon, and Cadillac Escalade. The vented, smooth-surface design is paired with a directional finish and a rust resistant coating to help protect the non-braking surfaces from corrosion during everyday use and seasonal exposure. For service work on a Chevrolet Silverado 1500 rear brake rotor or a GMC Sierra 1500 rear brake rotor, this part number BD126457E matches the listed 345mm rear rotor application.

This part cross-references Centric Parts 120.66065 for the same application.

What It Helps Address

  • Rear brake pulsation caused by rotor wear or uneven braking surfaces
  • Corrosion on exposed rotor surfaces from road moisture and salt
  • Reduced braking consistency from heat-related rotor wear
  • Noise or vibration associated with worn rear rotors
  • Service replacement needs on GM rear brake systems with 345mm rotors

Installation Notes and Tips

Verify rotor diameter, thickness, and rear position before installation. This rotor is listed for 6-stud wheel applications on many 2007-2019 GM full-size SUV and pickup platforms, including rear brake service on the Cadillac Escalade, Chevrolet Tahoe, GMC Yukon, Chevrolet Silverado 1500, and GMC Sierra 1500. Pairing Wagner rotors with Wagner brake pads supports matched brake system service.

Quality Assurance

Wagner Brake premium rotors are built with a focus on performance, corrosion resistance, and straightforward installation. BD126457E is engineered to meet the dimensional and material requirements listed for the application, with a rust resistant coating to help maintain rotor condition over time.
