I thought the reason for the residual check valve was to keep a small
pressure on the cups in the wheel cylinder to keep it from leaking. Some
cups had spring backings that eliminated the need for the residual pressure.
It's not just a check valve, it maintains a small (residual) pressure on
it's output, until it leaks down of course.
