Normally the older Oldsmobile station wagons have them. i used a tun of them years back. But with the newer brake systems you really dont need them but they work great. Just hook up a few wires and install the booster in the car. But there is nothing wrong withn a vacuum unit other than running a big cam. And i have used electric vacuum pumps and not even use the engine vacuum, There are several options. Yes Body man has a great project going on and a very professional build @ THAT. Very nice work

WHAT!!!!!!!!!!! Anyone that has driven or for that matter moved a car with a bad booster or the engine off or no vacuum to a booster will tell you it is almost impossible to stop it. Frankly i do not believe anyone on this planet could drive a car with no vacuum going to a booster for 4 seconds not to mention you said you drove it for 4 years ?????????? In my view impossible and this is from my 48 years turning wrenches. And if the vacuum T broke i believe that it would have took 5 seconds to FIX!! But whatever!!!!

The car you said you did this on has a pedal ratio of 3.7-1 and with a hybrid brake system it is unthinkable in my view that it could be driven safely with no difference and a state inspector would pass it on an inspection!!! But then again you have some very strange story's!!!

a lot of things seem to go over your head quite often. if you can lock up the tires, I would consider it to be safe enough to drive on the road. but the again, I seem to make impossible things happen every day.

I can't think of any other reason to do away with a vacuum booster that is already there and works

Simple because when you build performance engines you normally do not have enough Vacuum for good brake performance!!!!!!!!!!!!!!!!!!!!!!

yep, i can think of a few reasons to switch to hydroboost assist, vacuum being only one of them, what happens with the vacuum booster breaks for instance. or if you loose a vacuum line? not to mention that hydroboost is much more consistent regarding pedal pressure.

rubbish, my old 84 F250 with the diesel engine had a vacuum pump take a dump, which meant i lost the power assist brakes, along with the vacuum accessories, and it never bothered me driving that truck across country, or around town for four years that way. the only thing i noticed was an increase in pedal pressure required to use the brakes, but i got used to that, heck the clutch pedal required more effort than the brakes did even without the booster working.

I would say that each system has its advantages but why would you switch to the hydraboost if you were already vacuum and have adequate vacuum to support it? You have to be making some serious HP to kill the motors ability to make good vacuum or be running a monster cam profile. So if vacuum is an issue then hydraboost is definitely an option or as Tom and other have pointed out an electric system of sorts will work well too.

I will throw this out there, how often have you had a vacuum booster fail versus a power steering pump? I think that answer will vary from person to person so neither is really a good reason to base this decision on.

I have run some very large trucks at work. they rate them for under 26k gvwr to try to keep without a cdl. they also almost always have either powerboost setups or old school vacuum assist brakes. I have thrown a belt on the top of a mountain with a good 50 miles worth of dirt road and no cell service. when the hydroboost system fails, your in for a good hike and sometimes days without pay. I know why I prefer vacuum assisted.brakes.

I'll chime in super late on this. The only reason hydroboost is used from what I can remember is when engine vacuum isn't easily available (turbo, diesel) or the brake booster won't fit (sn95, new edge mustang). Hydroboost actually takes power from the engine by loading the power steering pump. Vacuum power robs no power, so why not use it if you can?
