Ford F-350 Super Duty hydro booster issue causing brakes to apply on their own while driving on Ford F-350 Super Duty

Some Ford F-350 Super Duty owners report experiencing hydro booster issues that cause the brakes to apply on their own while driving. These problems can stem from malfunctions in the hydro booster, which is crucial for the braking system's operation. A common symptom reported is that the brakes may apply and remain engaged until the pressure is bled off at the wheel cylinder. Additionally, some owners have noted that the brakes can lock up while driving, indicating a potential hydro booster failure. A loss of hydraulic pressure from the power steering pump can also lead to the brakes applying unexpectedly.
