The past couple times I've drove my F-350, after the motor has warmed up and been driving for a bit I'll start having brake problems. The brake pedal becomes extremely hard to depress and the truck will not slow down, hardly any at all. Pumping the brakes does not help at all, still the same result. Its all I can do to make it safely home.
I've asked a few folks and they've said perhaps: Vacuum pump, vacuum hose are two possibilities?
Any help is appreciated.
