First, what kind/year vehicle and brake system is it? Second, proportioning was not built into OE master cylinders, but
residuals were, and only for drum brakes.
Most disc/drum masters had a residual in the rear drum circuit up to the mid '70s, then they went away. So, you
may have an internal residual, depending on what year/make dual master you use will, but will have to add an inline 2 lb valve in the front system if the calipers are higher than the master cylinder.
