One is to apply a single valve in the common line from the reservoir, blocking the return flow and the other is to use dual valve between the master cylinders and the brake cylinders. The second is apparently sold by Lancair and the first is apparently more commonly used, especially in RVs. The first method would seem to be lower in cost and lighter in weight, but might be less effective as there is more compressibility involved. Any comments on which is better?
