Ford bulletin SSM 54448
Ford filed this with NHTSA as a service bulletin dated Dec 16, 2025, received Jan 6, 2026, about the service brakes. It names 40 model years (2017–2026). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2017-2026 F-Super Duty vehicles may exhibit a pull/drift condition during braking. This may be due to the brake pads needing to be broken in. Repeated, heavy brake applications may assist to resolve the pull/drift condition. The Workshop Manual, Section 206-00 Symptom Chart for vehicle pulls or drifts during braking has been updated to reflect this information.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 54448 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the SSM 54448 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does SSM 54448 cover?
The manufacturer filed it against 40 model years: 2026 Ford F-250 Super Duty, 2025 Ford F-250 Super Duty, 2024 Ford F-250 Super Duty, 2023 Ford F-250 Super Duty, 2022 Ford F-250 Super Duty, 2021 Ford F-250 Super Duty and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
