hydroboost

Thanks for posting pic! Do you know what year astro van you got it from? I'm thinking of doing same and buying a remanufactured unit, but not sure what year to shop for! Also, what master cylinder did you decide to go with? I'm assuming you have disc all the way around? Also, there is some talk about using a aluminum plate adapter on firewall, did you find this necessary? Thanks in advance!!!!

94 astro van I believe. The master cylinder is from a 96 Camaro. I have front disk, rear drum brakes and never used any aluminum plate adapter. go to the junk yard and get your hydroboost. they easy to rebuild and it will save you.
