Yes. As Craig found, the 1:1 in the Packard requires extreme effort in a master designed for 3 or 4:1. The BTV is not a master cylinder in the conventional sense. It uses a long stroke with a narrow rod that never touches the cylinder walls to displace or squeeze the fluid out whereas the modern units use a short stroke and larger surface area to push the equivalent volume ahead of the piston.
