True, but the front caliper pistons only move a small fraction of the
movement of the rear wheel cylinder pistons. The volume of fluid in each
case is the same.
In Berrie's case, I suspect a small blockage in the MC.
Unless, he is checking it with the lines open/disconnected. In which
case, it's normal!.
What happens with the tandem cylinder is if one system (front or rear)
looses pressure, the other internal piston continue to apply pressure to
it's line, while at the same time closing the gap between the two (front
and rear) pistons. The result in a bench check, would be to have no
pressure on one or the other and good pressure on the second.
