Sounds like your pressure switches are failing on the main control valve. This will also cause the engine speed control to not function correctly.Try using the backup mode switch to override the controller and pressure switches. If the swing brake stays off, replace the implement pressure switch on the main control valve.If this does not fix the problem, the wiring could be damaged or the swing brake solenoid could be failing.
