Wasn't the main advantage of Hydraboost systems that U could "hold" better w your brakes at the line, build more boost and get better 60' times ?

Don't know if anyone mentioned it, but Mark Savitske, a GN suspension guru, offers a hydraboost kit for ~ $500. He's damned helpful, too. www.scnc.com

I was thinking about it, and was wondering if maybe I should upgrade to an AGR pump when I do it. How's everybody's experience been w them ? They claim they're stronger and polished and all that, but I thought I recall some guys said they had some problems.

I don't know if March has one of those polished reservoirs for our pumps, but if not maybe I need to buy a new GM one. From what I have seen, it's pretty tough to separate the pump from the reservoir w/o destroying the reservoir. I think they are still available from GM for ~ $86 (Dal Slabaugh).

That website address I just gave was wrong - it is www.scandc.com

i love trying new things, and hydroboost was on my list. ive got a booster and master cylinder from an astro on the way ($75), and found that the factory astro lines list for around $25 bucks from advance auto parts website. i will be stopping tomorrow to order those (i love having advance right behind my house ). if all goes well should have less than $200 bucks in it, and there seems to be no real disadvantage in this upgrade!

What year of astro van did you get that hydroboost from? This is going to be my next project..

Re: My hydroboost install q ?

im not exactly sure, the booster and master cylinder were already pulled, but i believe all astro van hydroboosts are the same. the plate to mount it to the firewall is flat on early 90's, and after like 95 or so they are angled. ill shoot some pics of everything if someone wants to host them.

That's $25 each right? For the three hoses? Have you finished this up? Was looking at the posts and the diagrams for making the lines. I figure I should probably stick with something pre-made or else I'll do it wrong

Noticed that the parts stores carry the GM replacement lines. Just wondering who else did it with the non-bling stuff.

Re: My hydroboost install q ?

I just picked up a 91 astro hydro unit.

I noticed the pushrod (pedal side) is about 1/2" shorter and the hole in the pushrod is 1/16" larger.

was going to just cut off the vac booster push rod and weld it to the hydro to keep the correct length and diameter hole. has anyone done this and should I worry about heat effecting the hydro when I weld it?

Re: My hydroboost install q ?

I had to weld my firewall flange to my hydroboost unit . Although you should be able to disassemble everything to weld the rods together .

brian,
i posted this already. get u a hydro setup off of a late model astro or safari van. i got mine @ the junkyard off of a 98 gmc safari, ordered a adapter from e @ turbotime and vioala direct bolt up. as far as the lines go. you can use the ones off the safari/astro or use braided hose. earls makes o-ring fittings that will screw in the feed and return on the hydrboost and the steering gear.

What do you do with the line on the top of the hydroboost unit that normally goes up to the remote reservoir/tank on the astro vans?

I'd prefer to run the stock pump and not have a remote reservoir/tank.

I did see that.. But I wasn't sure what was done with that fitting that normally goes to that remote reservoir/tank. Is that what the 3/8 return line and T is for?
