Hydro-Boost Brakes

I'm looking at two different trucks right now. One is a Job 1 truck that has everything on it that I want and the other is a Job 3 truck with most everything. The Job 3 truck has hydro-boost brakes. Can someone explain to me what hydro-boost brakes are......is it good or bad?

And would ya'll stay away from the Job 1 trucks? I know they are prone to radiator problems, have the smaller air dams and not up to speed on the updated flashes, but all that is easily corrected. Any other reason not to purchase a Job 1 truck besides that it's been sitting on the lot for over a year getting baked in the sun?

Works fine for folks that know how to drive.

The "power" in normal power brakes on gasoline-powered vehicles are boosted by vacuum pressure. But diesels don't make vacuum, so if you want ordinary vacuum-powered brakes, you have to add a vacuum pump to your diesel truck. That's what Ford did on the new trucks to give them vacuum-powered brakes.

Hydro-boost brakes on our diesel trucks are powered by hydraulic power that comes from the same hydraulic pump that powers the power steering. Works fine unless you attempt to stand on the brakes while stopped and then try to turn the steering wheel at the same time. If you've ever driven a vehicle - especially a farm tractor - that didn't have power steering, then you know to get the front tires rolling before you try to turn them. But city kids these days never learned to drive without power steering, so they think something is wrong with their truck when they can't turn the front wheels while having the brakes firmly planted in the firewall. The only thing wrong is the hydraulic pump is not big enough to allow you to use max power for both the brakes and steering at the same time.

If the truck has the options you want, then the only reason not to buy it is it's been sitting on the dealers lot a lot longer than a Job 3 truck. The last Job 1 truck was assembled in July, 2007. That was over 14 months ago. The first Job 1 truck was assembled in January, 2007, which was over 1.5 years ago.

Thanks Smokey. So the listing of hydro-boost brakes on the Job 3 truck isn't anything new or an upgrade? It's the same type of braking system that's been on the diesel trucks since at least 99........correct?

Correct. For 2008 Job 3 models and 2009 models of SRW pickups, vacuum brakes are standard with gas engines, and hydro-boost brakes are part of the diesel engine pkg. I thought the vacuum brakes were optional with the diesel engine, but not according to the Order Guides - at least on SRW pickups. On yours, since vacuum brakes and gas engine are standard, the sticker shows both the diesel engine and the hydro-boost brakes as options. But the hydro-boost should be a no-cost option, since you paid for it as part of the price for the diesel engine.

Conflicting info. I got that "thought" from the "What's new for 2009..." Ford put out last spring. It's posted at the top of the 2008-up Ordering Info forum. It included the blurb:

Diesel F-250 Vacuum Brakes:
- Vacuum brakes will be standard on all diesel F-250s.
- Same system as used on gasoline SRW vehicles.
- Requires addition of vacuum pump on FEAD.
- Dual alternator F-250s will retain Hydro-Boost.
- Hydro-Boost LPO will be made available on all diesel F-250s.
- All DRW and diesel F-350 SRW vehiclesretain Hydro-Boost.
But the current 2009 order guides for F-250 and F-350 still show the same standard brakes as the 2008 models, with no options, i.e., the gassers have vacuum and the diesels have hydro-boost. So apparently, the vacuum brakes as standard on 2009 F-250 diesels will be a "late availability" change, perhaps as Job 2?

None of that applies to your 2008 Job 3. But it's frustrating for us that try to keep up with how to order a new PSD so we can properly inform members of TheDieselStop.

When I drive a gas vehicle, like my wife's Frontier, I hate it. I am so used to brake pressure being even, there when you want it, and firm. Squishy gas vehicle brakes feel odd to me. I do not know why someone would want them on a SD. Granted, I never new the existed before buying one, but now that I have them I hate vacuum brakes. And like others said, if you learn how to drive, there will never be an issue with them.

Sorry to dig up an old post, but do you think Ford decided to ditch the vacuum brakes? I sure hope so.
