Wagner Brake DSX125660E Disc Brake Rotor - Rear

Brake Rotor for Heavy-Duty Rear Applications

Wagner Brake DSX125660E is a vented disc brake rotor built for demanding stopping conditions. It combines cast iron construction, a full cast design, and a rust resistant coating to support consistent braking performance in heavy-use service.

Key Features

• Cast iron rotor with full cast construction for strength and durability
• Vented design helps manage heat during repeated stops
• Rust resistant coating helps protect the rotor surface
• Smooth, directional brake surface for controlled contact
• 8-lug pattern for the listed rear applications

Detailed Description

The Wagner Brake DSX125660E disc brake rotor is engineered for vehicles that see frequent braking and heavier loads. Its superior metallurgy and heat management focus make it a practical choice for fleet, delivery, municipal, and emergency-duty use. This rotor measures 12.835 inches in outside diameter, 0.472 inch in nominal thickness, and 3.878 inches in overall height, with a vented, directional surface design.

Fitment includes 2000-2005 Ford Excursion, rear; 1999-2004 Ford F-250 Super Duty, rear; and 1999-2004 Ford F-350 Super Duty, rear. For buyers searching for a rear brake rotor for Ford Excursion or Ford F-250 Super Duty and Ford F-350 Super Duty applications, DSX125660E matches the listed configuration and dimensions. This part cross-references Bosch 66823 and Raybestos Brakes 66823 for the same application.

What It Is Used For

• Replacing a worn rear brake rotor with the correct vented design
• Addressing brake pulsation caused by uneven rotor wear
• Restoring braking consistency under repeated stop-and-go use
• Replacing a rotor affected by rust or surface corrosion
• Maintaining proper braking performance on heavy-duty trucks and SUVs

Installation Notes and Tips

Verify rear fitment, outside diameter, thickness, and 8-lug configuration before installation. Inspect pads, caliper condition, and hub mating surfaces during service to help ensure even contact and proper rotor seating. Confirm the directional surface orientation during installation.

Quality Assurance

Wagner Brake designs SD rotors with metallurgy and heat management in mind for severe-duty braking environments. DSX125660E is built to support durable service in applications that make frequent stops and carry heavy loads.
