Thanks,Grant! I guess you summed it up nicely. Now,HOW do you figure the volume of the stock master,and the combined volumes of the wheel-cylinders? The same reservoir dimensions,as well as the same stock bore dimensions? How are we going to know,(before installing) that the "new" vacuum-booster performs as well as the stock hydro-vac? Sorry for the "dumb" questions,but I'm still a novice at this stuff.
