My G Body has 1/4" to the front and 3/16" to the rear. It has Aerospace disks on all four corners and stops decent. When I first purchased the car the residual valve, which was located in the factory proportioning valve, was still there. It caused severe drag on the rear brakes. Since removing it the brakes release better but not as well as I'd like. When the car sits I do need to pump the brakes up a bit because there is no residual valve. Another oddity I noticed is, if I want to coast down the lanes and let the brake off gently it doesn't want to move. If I apply firm pressure and quickly let off the brake pedal it rolls right away. Has anyone ever noticed that with their system?

Todd, that is impressive you can hold at 4000; I can barely hold 3000. By the way, thanks again for you help at Cecil!
