Overview

Wagner Brake BD126503E is a rear disc brake rotor engineered for direct replacement applications that require a 331 mm vented rotor with corrosion resistance. It is built for vehicles such as the Buick Enclave, Chevrolet Traverse, GMC Acadia, GMC Acadia Limited, and Saturn Outlook.

Key Features

  • Vented rotor design for consistent brake cooling and heat management.
  • Full cast construction in cast iron for stable braking performance.
  • Rust-resistant coating helps protect non-braking surfaces from corrosion.
  • Smooth, directional finish supports even pad contact and rotor operation.
  • Fits rear brake applications with a 331 mm outside diameter.

Detailed Description

Wagner Brake BD126503E is a premium brake rotor built to match the fit and function required for rear brake service on select GM crossover applications. The rotor uses full cast cast iron construction, a vented design, and a smooth directional surface to support consistent braking response and heat dissipation. Its rust-resistant coating adds protection where corrosion is a concern, especially on the non-braking surfaces. This part number, BD126503E, is listed for rear fitment on the Buick Enclave, Chevrolet Traverse, GMC Acadia, GMC Acadia Limited, and Saturn Outlook.

Wagner rotors are engineered with a focus on performance, corrosion resistance, and straightforward installation. For service work on the Buick Enclave or Chevrolet Traverse, pairing the rotor with matching Wagner brake pads helps maintain a balanced brake system. Part number BD126503E also cross-references Monroe Shocks & Struts 172286 and 182286 for the same application.

What It Helps Address

  • Brake pulsation caused by worn or uneven rotor surfaces.
  • Reduced braking consistency from heat buildup in the rotor.
  • Corrosion on exposed rotor surfaces.
  • Noise or vibration related to rotor wear.
  • Service replacement needs for rear brake maintenance.

Installation Notes and Tips

Verify rotor diameter, wheel stud configuration, and rear application before installation. Confirm the vehicle uses a 331 mm rear rotor and compare the existing rotor dimensions to BD126503E. Clean the hub mounting surface before installing the new rotor to help reduce runout concerns and support proper brake operation.

Quality Assurance

Wagner Brake designs premium rotors with corrosion resistance and installation ease in mind. BD126503E is built to meet the demands of rear brake service on the listed applications.
