Broken vacuum pulley
I was on my way to Home Depot tonight..... pulled off the feeway and was amazed that my brakes were all but gone.... brake pedal very hard to push down, and I could not completely stop with the truck in gear. BTW, I am driving a 1997 F250 Power Stroke..... anyway, I put in neutral and pulled off the side of the road, popped the hood open, and noticed fluid down by the power steering pump. I then noticed the belt was only half way on the power steering pulley and I thought that shouldn't have anything to do with the brakes. Well, turned the truck off and then noticed the vacuum pump pulley was cocked a little sideways, and I could wiggle it a little with a screwdriver. Having about 5 miles to go back home, I took some back roads and used neutral and e-brake when I had to stop.
Now for the question..... if the vacuum pump pulley is broken, am I going to have to replace the pump itself also? I haven't got into it too much yet because it got dark, so I am not real sure what I'm dealing with. But is the shaft, that the actual pulley is on, part of the pump itself, or is it part of the pulley? And how easy or hard of a job will this be? Thanks in advance.

It is not a hard job. Mine went out several years ago on the interstate. You got lucky. I was away from home with no tools on the interstate. The S.C. DOT guy helped me get off the highway and I went to advance and had to order the pump overnight. Put it on the next morning and away I went. My pump completely locked up. Get a new belt while you are in there.

How much extra pressure are we talking about without the vac. pump?

If you are asking how much pressure is required to stop it, then you will have to grab the wheel with both hands and both feet on the pedal and push/pull as hard as you can and will begin to slow down a bit. I doubt you can stop on a down grade unless you use the e-brake and down shift all at the same time.
