Service bulletin SSM 46370
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
SOME 2017 F-SUPER DUTY VEHICLES EXHIBIT CONCERNS RELATED TO BRAKE DRAG. UTILIZE WORKSHOP MANUAL (WSM) DIAGNOSTICS IN SECTION 206-00 TO VERIFY THE CORRECT INSTALLATION OF THE STOPLAMP SWITCH. IMPROPER ADJUSTMENT OF THE STOPLAMP SWITCH CAN CAUSE THE BRAKE PEDAL ASSEMBLY TO LIGHTLY APPLY THE BRAKES RESULTING IN DRAGGING CONDITION.

| SSM 54448 | 2026-01-06. Service bulletin. Some 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. |

| SSM 51261 | 2023-01-06. Service bulletin. Some Ford and Lincoln vehicles may exhibit noise when the brakes are applied. When diagnosing and repairing brake noise conditions, use the Workshop Manual (WSM) and the appropriate pinpoint test in section 206-00. The brake rotors should only be machined if directed by the WSM because one or more of the following conditions are present on the braking surface: scoring, excessive corrosion/rust or pitting, bluing/discoloration and/or heat spots. For additional information, refer to WSM section 206-00. |
| SSM 51120 | 2022-10-11. Service bulletin. Some Ford and Lincoln vehicles may exhibit noise when the brakes are applied. When diagnosing and repairing brake noise conditions, use the Workshop Manual (WSM) and the appropriate pinpoint test in section 206-00. The brake rotors should only be machined if directed by the WSM because one or more of the following conditions are present on the braking surface: scoring, excessive corrosion/rust or pitting, bluing/discoloration and/or heat spots. For additional information, refer to WSM section 206-00. |
| SSM 50718 | 2022-05-03. Service bulletin. Some 2017-2022 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. The Workshop Manual, Section 206-00 Symptom Chart for vehicle pulls or drifts during braking has been updated to reflect this information. |
| SSM 50064 | 2021-09-04. Service bulletin. Some 2013-2021 Ford and Lincoln vehicles may exhibit noise when the brakes are applied. When diagnosing and repairing brake noise conditions, use the Workshop Manual (WSM) and the appropriate pinpoint test in section 206-00. The brake rotors should only be machined if directed by the WSM because one or more of the following conditions are present on the braking surface: scoring, excessive corrosion/rust or pitting, bluing/discoloration and/or heat spots. For additional information, refer to WSM section 206-00. |
| SIL 790 | 2021-04-06. Service bulletin. It has been discovered that some hydraulic lines installed by Altec may be in contact with chassis air brake line(s). Some DOT inspections have considered this to be a violation of federal regulation 49 CFR ยง 393.45 b 2. Over time, chafing of the air brake line(s) could result in loss of air pressure and reduction in braking performance. Altec requires the routing of the hydraulic lines to be inspected no later than the next periodic maintenance interval. The affected unit are some T40P cable placers installed on Ford F750 chassis from May 2015 to January 2020 |
| SSM 49010 | 2020-08-04. Service bulletin. Some 2017-2020 F-Super Duty vehicles may exhibit concerns related to brake drag. Utilize Workshop Manual (WSM) diagnostics in section 206-00 to verify the correct installation of the stoplamp switch. Improper adjustment of the stoplamp switch can cause the brake pedal assembly to lightly apply the brakes resulting in dragging condition. |
| SSM 48450 | 2020-02-04. Service bulletin. Some 2016-2019 F-650/F-750 vehicles equipped with a 6.7L engine and an air brake system may exhibit inoperative cruise control and/or immediate transmission downshifting when releasing the accelerator pedal. This may be caused by an in range failure of the brake pedal pressure transducer (7920) that does not set a diagnostic trouble code (DTC). The Integrated Diagnostic System (IDS) can be used to view the WHEEL TRQ RAW PID in the generic function module (GFM). It displays the voltage value of the brake pedal pressure transducer. The voltage should be between 0.35 volts and 0.65 volts with the brakes released and will increase with brake pedal pressure. An inoperative transducer will not change with brake pedal pressure. Refer to Workshop Manual (WSM), Section 206-08 for the location of the brake pedal pressure transducer. |
| SSM 48299 | 2019-12-04. Service bulletin. Some 2016-2019 F-750 vehicles may exhibit an excessive or uneven amount (inner versus outer) of front and/or rear brake pad wear. For vehicles exhibiting this condition, it's recommended to use FC4Z-2001-F brake pad kit when replacing front or rear pads. Some vehicle applications will demonstrate improved brake pad wear after installing this kit. |
| SSM 47801 | 2019-04-08. Service bulletin. Some 2017-2019 F-Super Duty vehicles may exhibit concerns related to brake drag. Utilize Workshop Manual (WSM) diagnostics in section 206-00 to verify the correct installation of the stoplamp switch. Improper adjustment of the stoplamp switch can cause the brake pedal assembly to lightly apply the brakes resulting in dragging condition |
