So i bought this 47 2 ton. I got it running. Now times for brakes. So i want to go through the entire system. My question is ....there is a hydroboost on there I am told. Is it really a hydro? Isn't it more of an old school vacuum booster. I am debating getting rid of that and just using a master cylinder with a 1.25 or 1.5 bore with a 7 " vacuum booster on it. How much psi does that original booster give out psi wise? 1000?800?1200? What have many of you guys done for brake systems.
