Rear Disc Brake Rotor for Heavy-Duty Stopping

The Wagner Brake DSX126457E is a rear disc brake rotor built for vehicles that see frequent stops and heavier loads. It uses cast iron construction, a vented design, and a rust-resistant coating to support consistent braking performance on applications like the Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac Escalade.

Key Features

  • Cast iron, full cast rotor construction for strength and durability
  • Vented rotor design for improved heat management during repeated braking
  • Rust-resistant coating helps protect the rotor surface before and after installation
  • Smooth, directional brake surface for consistent pad contact
  • 13.571 in. outside diameter and 0.787 in. nominal thickness
  • 6-lug design with 3.346 in. overall height
  • Fits rear brake applications on select Cadillac, Chevrolet, and GMC trucks and SUVs

Detailed Description

Wagner Brake DSX126457E is engineered for rear brake service on a wide range of GM full-size trucks and SUVs. The vented cast iron rotor helps manage heat buildup, while the directional surface and smooth finish support even pad engagement. This rotor is a direct fit for applications including 2007-2020 Cadillac Escalade rear, 2007-2020 Chevrolet Tahoe rear, 2007-2018 Chevrolet Silverado 1500 rear, and 2007-2018 GMC Sierra 1500 rear. It also fits 2007-2014 Chevrolet Suburban 1500 rear, 2007-2014 GMC Yukon XL 1500 rear, and 2015-2020 GMC Yukon XL rear.

This part cross-references Raybestos Brakes 580422 and Centric Parts 120.66065 for the same application. The Wagner SD rotor line is built around metallurgy and heat control for vehicles that stop often and carry substantial weight, making it a practical choice for fleet, delivery, municipal, and emergency-duty use.

What This Rotor Helps Address

  • Brake pulsation caused by uneven rotor wear
  • Heat buildup during repeated stop-and-go driving
  • Surface corrosion on exposed brake components
  • Reduced braking consistency under heavier vehicle loads
  • Rear brake service needs on GM trucks and SUVs with 6-lug hubs

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and rear position before installation. Clean the hub mounting surface thoroughly to help prevent runout and uneven pad wear. Inspect brake pads, calipers, and hardware condition during service, and confirm the rotor surface is free of protective residue before use. This rotor does not include bearings.

Quality Assurance

Wagner Brake designs SD rotors with high-strength metallurgy and heat management in mind for demanding braking environments. Part number DSX126457E is built to meet the needs of rear brake replacement on select Cadillac Escalade, Chevrolet Silverado 1500, and GMC Sierra 1500 applications.
