As long as I'm bothering the experts with silly questions... :-)

If I understand it, one should not use master cylinders designed for an all-disc
system on a vehicle that has drum brakes, because some (most? all?) wheel
cylinders need residual pressure to retract fully and keep the cup seals closed.
Most disc-disc master cylinders don't include the necessary valve(s). This could
result in dragging brakes and/or air in the wheel cylinders.

Any truth to this??

thanks
