I have an adjustable Wilwood proportioning valve on the system and have it opened up all of the way (the car is 4 wheel disc).
While this may sound like an elementary question, is there a M/C that is evenly proportioned through the piston stroke so the valve can do it's job?
In advance, thanks for the consideration.

When you say "I noticed the rears come in a fair amount after the front" is this while bench bleeding or on the car.
Off car...its by design. One port will have more volume.
On car... You may need to bleed again or you have a possible push rod issue.
