I replaced the entire hydro vac on my 59 gmc 2 ton with a fire wall mounted unit.... dual master booster assembly, I was a little skeptic at first, because the vacuum booster was so much smaller....I was amazed at how much better this worked! I also got rid of a wheel barrow full of rusty stuff in the process. I use this truck like a truck as well...........never have had a lack of brakes. easy install & easy to bleed. Has a reservoir for the front and one for the rear. 378 bucks for a very nice kit!
