Hydroboost conversion bracket..Now the astrovan unit is a true bolt on!!!!

[Pat Adkins]

I am in for 1 of these brackets , Hold me 1 if you have it, gonna try to catch up with you at mich. ave. cruise. thanks

 

[GNRick]

I put the whole thing in a vice clamped the nut with it and spun th hb off to tighten i used an air hammer if ir takin ot off at the yard just undo the four bolts on the mounting plate

I got my Astrovan HB today. It came with the bracket installed. So I see that the Kent Moore tool isn't needed, since the nut is on the outside holding the bracket on.

I looked at my hydroboost unit and the casting numbers on it are 044 this unit fits the powermaster pedal without using a bushing/spacer idk what year astrovan it came off of i wasnt paying attention when i got it out of the pull a part yard....

As far as the availibility of hydroboost units for the future Gm is still putting them on their heavy duty trucks my 06 and 07 2500 vans both have hydroboost the accumulator is a different color and bigger but other than that the unit visually looks the same im no expert maybe someone that knows more will chime in.....

What kind of master cylinder are you guys using?

The one I got from the local yard has 174 on one side and 962D on the other side. The Cardone unit that I got from Advance has 308 on one side and 962D on the other. So they both have 962D on one side if that means anything. I would have replied sooner but did not get a notification.

 

[bass87gn]

I'll take one of these if there still available???

I bought the mid 70's Corvette MC (I think that was the C3 corvette) that Hydratech recommends with their unit. I got the Astro Van MC for the Astro Van hydroboost. Don't have results for either one yet, hoping to have the Hydratech working tomorrow. Turboburick has the Hydratech all working on his car with the Corvette master cylinder.

what year astrovan did you get the hb from and what about the lines do you get it from the same van ?

 

[turboc87gn]

No updates yet fellas going by my friends this weekend hope to get the ball rolling soon on them...

 

[turboc87gn]

Heres an old thread that has the master cylinder/lines info....The video link dosent work which sucks because it had all the earls fitting part numbers...ill look for it again though....http://www.turbobuick.com/forums/threads/hydroboost-lines.325517/page-2

I think the HB is from a mid 90's astro van. I had custom lines made for my Hydratech unit. Haven't installed the astro van unit yet on my other TR. I plan on using an astro van master cylinder since I know it works with the astro van HB. The resevoir is a little larger, hoping the hood will close. I didn't get the lines from the junk yard with the astro van unit. Probably not a good idea to reuse the old lines as dirt can get into the power steering pump and damage it. I would recommend either have a hydraulic shop (or NAPA) make you lines or get the Aeroquip lines. I used the factory "U" shaped pipe that connects to the power steering pump.
