GMC 3500 sierra Dully no brakes no steering?

Got in my truck this morning and had no function of the brakes or steering. Worked fine yesterday, what would be the cause of this?

Update:

Yes it is a diesel... Is that accessory the same as the serpentine belt?

    Guessing you have the Hydro-boost brakes, which uses the power steering pump for brake assist.

    Low/no power steering fluid, or missing drive belt.

    Edit...

    Yep, the serpentine belt would be the one that would be missing.
