Hydroboost Info
Quick question to those of you that have converted your brakes to hydroboost. Have you had any problems with any of the brake components (lines, hoses, calipers, ect) failing due to the added line presure? And have you noticed any diminished performance from your power steering pump? We were using 2006 Crown Vics at work that had undersized power steering pumps. When you would break hard you would lose your steering. Fun! Ford recalled them and they finally had ours fixed after I wrapped one around a pole. Don't want to do that to my truck!

The 2006 Crown Vic has hydroboost? You 100% sure on that?
The issue you're talking about was somewhat common for the Chevy trucks, not so much with Fords, but even then you'd have to be pumping the brakes and spinning the steering wheel like a ship rudder from the medieval times to actually notice it.
As for braking systems components failing - you'll blow lines and hoses if they're old and questionable, but that's all there is to it - replace any bad steel lines and rubber hoses with new ones when upgrading to the hydroboost, and you'll be good to go.

Sure they mis-quoted what they replaced. Every one I've worked on including interceptors are all vacuum boost. Are you full? Under the hood you would know the difference, take a look.

Same here, I worked on the 2009 police cruisers before the PDs even got them in service, never saw a hydroboost in them, just the vacuum booster. Them cars do have speed-sensitive variable steering assist tho, so if that went bad it's entirely possible the steering assist got lost as speed decreased, which is actually just the opposite from the way it should be working.

Got to love a computer controlling the steering, I think I just might have to have one of them.

My CVPI sure does not have hydroboost.... I'v never seen one that had it.
Star, I like that steering system.
I have never heard of it failing and it makes the steering much less touchy/more feel of the road at high speed.

Well I started out with manual steering and have driven a litle bit of everything even air assist and so far have had no trouble with any type of steering as long as it was in decent shape. I guess I just don't like the idea of something else to go haywire especially on the steering.

Starmilt, the variable steering assist system ain't much more than a solenoid that controls how much fluid flow will go through the steering and how much will bypass it - lower speed calls for mure flow through and so higher assist, at high speeds the bypass increases and the steering assist goes down. Dumber that a cruise control really. That self-steering mess is on the new MK-whatever Lincolns, they are the ones that parallel-park on their own, the Panther platform (Crown Vic, Grand Marquis, and Towncar) only make the steering feel stiffer when you get on the interstate so you don't roll the car if you jerk the wheel too hard.

Well so far I haven't rolled to many cars because of the old fashioned steering.
I have always thought every body needed to learn to drive by themselves that way when something goes wrong they don't panic or wreck or run over someone like me.
It sounds to me if it is selonoid controlled it has a wire to it.

Well I never had a liscence that made it legal but have logged more miles than most at 100 plus and did it without any electronic aid. There are already lots of drivers out here that have never driven a vehicle without antilock brakes, now we have vehicles that will apply the brakes for you, and electronic controlled steering. I have always belived everybody should learn to drive the old way first then if something wasn't right they could handle it without panicking. If all the old goats and camaros,and roadrunners were so dangerous at high speeds there wouldn't be many of us around anymore. lol
