Thanks.... I'm guessing that the residual pressure valve is part of the master cylinder (at least for the B-bodies)? If so then it sounds like I need to swap out the master cylinder for one that was used for drums, correct? If that doesn't solve my problem singlehandedly, it seems to me that it's still something that should be corrected.
