2006 GMC Duramax no Brakes or Power Steering
 

Went to go get hay today and the brakes on the Dmax decided not to work. Had to use the E-brake to stop it. I tried to finaggle it out of the garage and realized that the power steering was completely gone as well and because of the mirrors it is stuck in the garage. I am completely stumped and no one seems to have any idea. The dealer is closed until Monday and I need guidance..

HELP!!!!!!
