Lostmarbles, I've read as many post on this thread (and the previous thread) as I have time to read (not many), and it appears that there is alot of "the blind leading the blind" on this subject matter.
Put simply, drum brakes need approx. 10 lbs. residual pressure to hold the brake shoes up to the brake drum, and disc brakes need only 2 lbs residual pressure to hold the pads up to the rotors. If you left the OE 6 lbs residual valve in the master cylinder after a rear disc brake conversion, the rear brakes would always be applied, and probably burn up or wear out prematurely.
This subject matter really does not have to get more complicated than that!!!!!
