Brake line size

[117X]

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!

I have Aerospace brakes on my car. The only time they drag is when the pads get worn on a skew. If your pads are more than a couple of seasons old than pull the pads off and check to see if they are worn unevenly. If they are they will drag. put some new pads on and recheck.
