Hey everybody...

I just inherited a 57 6400 that has been sitting forever. Got the engine running and can move the rig around but I have no brakes and I cant get the 2 speed axle to go into high range. I was told by one of grandpa's brothers that the old truck had a vacume problem so I started diggin around and have seen some sort of vaccume thing connected to the master.. Just trying to figure out where to start.... Emergency brake works otherwise I would be in real trouble...


Help me please????
