Morris, your comments make sense, thanks. The lower pedal only occurs through a right left transition with no braking, then the next corner, lower pedal. Around one corner and the pedal is pretty good. I am pretty sure it is spindle flex. I have spoken to some of the shelby spec racer guys which have similar setup's and they have had the same issue. The solution is bigger bearings which is tough to do with pin drives and or float the rotors. I don't know that the residual pressure valve will fix a mechanical problem. The fix is either left foot brake and pump them once. Or, AP racing has some knock back springs that go behind the pistons in the calipers. Any experience with knock back springs? I might go up in rear rebound but I do not want to potentialy keep the inside rear lifted at mid corner and exit. Thanks again, Scott.
