If your master cylinder is mounted low, like under the floor, you need to put 2 lb residual valves in both systems. That helps to hold the pistons a little closer to the rotor and serves to give a better Pedal feel and height.
Check the specs on the "proportioning "valve you are running. It should be for a disc disc setup.It may (should) have a residual valve in both sides. Make sure it is plumbed in very near the master.
Early vette master cylinders use no residual valves in them.
Fact is stranger than Fiction
