Summary
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.
