My current project is a K30 that I am cutting down to make a Blazer (sort of). Anyway, it has the hydro-boost power brakes and I have never fooled with them before. Seems to me like just more high pressure lines to leak/blow so I thought maybe I would convert it to vac assist. Does anyone have any compelling knowledge/experience one way or the other?
