Bendix Friction SDR5139 Disc Brake Rotor - Rear

Bendix Severe Duty Rotor SDR5139 Overview

The Bendix Severe Duty Rotor SDR5139 is a rear disc brake rotor built for demanding truck and fleet braking conditions. It combines OEM-driven machining specifications with controlled manufacturing tolerances to support consistent brake performance on severe duty applications.

Compatible with select Ford F-150, Ford F-150 Heritage, Ford F-250, and Ford F-250 HD rear brake setups, this rotor is part of the Bendix Severe Duty Rotor SDR line for police and fleet use.

Key Features

• Mill balancing and OEM-driven machining specifications for consistent rotor finish and fit
• Focused application range for police and fleet vehicles
• OEM vane configurations to match original cooling design intent
• Manufacturing control with precise machining tolerances
• ACP alloyed-carbon performance casting for thermal stability and strength under severe duty braking

Product Line Details

The Bendix Severe Duty Rotor SDR line is engineered for work-duty trucks, fleet vehicles, and pursuit applications that see repeated braking loads. The SDR5139 follows that product-line focus with a rear rotor design intended to maintain stable braking characteristics in demanding service environments.

Detailed Description

Built for heavy-use braking systems, the Bendix Friction SDR5139 rear disc brake rotor uses alloyed-carbon casting technology to help manage heat and maintain structural strength during repeated stops. The OEM vane configuration supports airflow through the rotor, while precise machining tolerances and mill balancing help promote smooth operation and consistent contact with the brake pads. For drivers and fleet managers searching for a rear brake rotor for 1997-2003 Ford F-150 7-stud applications or a 2004 Ford F-150 Heritage rear rotor, the SDR5139 provides a direct-fit service part for those listed configurations.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Rotor Helps Address

• Brake vibration caused by uneven rotor machining or imbalance
• Heat-related brake fade during repeated stops
• Premature wear in severe duty rear brake service
• Inconsistent braking feel in fleet and pursuit use
• Rotor distortion from demanding truck braking cycles

Installation Notes and Tips

Fits 2004 Ford F-150 Heritage, rear, w/ 7-Stud Rotors; Bendix Severe Duty Rotor SDR. Fits 1997-2003 Ford F-150, rear, w/ 7 Studs; Bendix Severe Duty Rotor SDR. Fits 1997-1999 Ford F-250, rear; Bendix Severe Duty Rotor SDR. Fits 1997 Ford F-250 HD, rear; Bendix Severe Duty Rotor SDR.

Verify rear axle and rotor configuration before installation, especially on 7-stud Ford truck applications. Inspect pads, calipers, and hub surfaces for wear or contamination before installing the new rotor to help maintain proper braking contact.

Quality Assurance

Bendix Friction applies controlled manufacturing processes, OEM-driven machining standards, and precise tolerances to support consistent rotor quality. The SDR5139 is built as a severe duty brake rotor for demanding truck and fleet service.
