Thanks for the quick reply. I'm in go kart mode and only have about 15 miles on the car, just cruising around the neighborhood. The braking performance has been weak, but I rebuilt the calipers and have brand new rotors and pads (north east donor, everything was rotten) so I figured everything just hasn't had a chance to bed in. This discussion reminded me that I installed the valve but never adjusted it. I looked at it and found that it was all the way closed. I opened it all the way up but haven't been able to take it for a spin because it seems like all of Florida is underwater. I'll update you all after I go for a drive. Thanks for all the help!
