I found out the reason I've been having issues with flat-spotting. My brake system is in fail-safe mode. So how do I replumb around the ABS valve? Will I need a new proportioning valve? I'm dealing with a BMW four wheel disc's, so I won't need a residule valve like a drum system. Looks like just unpluging the actuator isn't cutting it with this particular system. How about the legality of a replacement master, if I can't get a proportional valve to work correctly?
