I see that the vacuum are standard now on F-250's, but hydro are still available. Which are better? Should I consider changing my options before I order to get the hydro-boost?

According to the parts catalog the 2008 diesel is hydroboost only. A diesel engine does not make any vacuum so a huge pump would have to be installed to use a vac booster. Hydroboost works great.

1997 F350 had hydroboost. The F250 had vacuum brakes which runs off a belt driven vacuum pump. I would rather have hydro.
The 2008 Superduty has a small electric vacuum pump and reservoir for the climate control accessories and EGR only. The brakes are powered by the power steering pump.

Job 3 order guide says SRW standard with vacuum boost brakes except with dual alternators.DRW standard hydroboost.Not sure why the change but that is what it states.

Ford has a brochure out on job #3 and it says that it is going to the vacuum bost brake to make it have the feeling of a car.
Why I don't know. The F450 will remain as is. That tells me that the hydro off the power steering is the best.
So I went for a job#2.

Go Hydro, The pedal Height and feel is way Better. Also havent had any probs at all with the ones in our fleet. However I have changed MANY vacum pumps .
I have the newest online version of Ford Catalog Advantage (updated weekly) and as usual it says nothing about the new vacuum option. I would get the hydro. If I had wanted to buy a car brake system I would go buy a car.
The belt driven vacuum pumps on the older model were usually good for around a 100k miles give or take 20k.
If the job 3 trucks have a vacuum option I wonder where the pump will be located. I doubt the electric pump will keep up to the demands of a brake system.
I wonder if thats a error on the job 3 option list.
Power 4-wheel disc/4-wheel anti-lock brakes with vacuum boost
are now standard on SRW with all engines. Power 4-wheel disc/4-
wheel anti-lock brakes with hydro-boost are now included on SRW
with the Dual Alternators and optional on SRW diesel for fleet only.
I will stand corrected unless its a error. Ford has been known to have errors on ordering option sheets before. They are not quite as bad as parts catalog errors though.

HydroBoost was only on the F-Superduty of the OBS style...All F-250 and F-350 used a vac pump driven by the belt to assist braking. The Vac assist works great but the Hydroboost does have a better feel to it IMO. I was driving a 2000 F-550 for a while and the brake does have a nice feel to it.

Are you paying attention?
I said that Ford has a brochure out on job #3.
It is in color. It is about 4 pages, if I remember correctly, and it is very specific in what it says about the brakes.
It is not an error.
They may change their minds, but it was intended to be as I described.
When the dealer I was talking with at the time put the options I requested in his computer, it rejected the hydro brakes, which means on that day it was not even an option although it could be now. That was about one week before Christmas.
In the meantime, I found a job 2 that had what I wanted on it, so I bought it.

Hey, I do this Ford thing for a living. (22 years) I have forgot more than you will ever know about these trucks. I am only as good as the information provided directly by Fords parts catalogs. The sheet that is on Bobby's webpage could be correct or possibly a mistake. Ford makes mistakes every day on things in writing. I see it every day. Catalogs and ordering guides are not the gospel. We have a few Job 3 trucks on the storage lot at the dealer I work at. I can go look at one tomorrow. Have you see a truck with a 6.4 and vacuum brakes?
If you will look above at my post above in quotations I stated that its possible.
The option being rejected on your order also leads me to believe that this is a typo error on the Job 3 sheet.
Guys like you kill me.

22 years with Ford and you don't have a clue, except that you know more than I know.
OK, you can read mine again SLOWLY and you will see that the computer rejected the hydro.
That was in agreement with what the color brochure said.
That was just before Christmas. Six weeks ago.
Now unlike you, I do not claim to know everything. All I have said is that I have seen this brochure, that it is in color, that it describes the vacuum brake and stated that it was to give the truck more of a car feel. If I recall correctly, there was something about "to make it easier for those who have cars and trucks" or something like that.
It appeared to be an attempt to make it easier "maybe" for our ladies to move back and forth from the car to the truck. Something like that anyway.
The brochure also said that F450's and F550's would remain as they are, which led me to believe that would be the best for someone like me who pulls horse trailers on very steep grades (9%).
Now go off on a pout if you like. All I have done is try to inform those here as to what I read and what it said to the best of my recollection. And it was in a Ford brochure, shown to me by a Ford dealership.

then what do you expect. I assume you are a internet educated genius. I don't profess to know it all but I am well educated on Ford vehicles and I am Master Certified with Ford Motor Company. I not above making mistakes as I pointed out in my previous post. My gain of experience and education continues daily.
My post was an attempt in helping a guy make a decision on what to order on his new truck not to argue with you.
There are just some people that won't listen or read.

Would you please note that I said that I read a Ford brochure given to me by a Ford dealer who was pricing a new truck for me.
I did not get that off the internet. I got it from a Ford Brochure.
Please pay attention. You are not doing well in class.
