The question is, is the MC *designed* for servo boost, or not? One designed
for a boosted system may well have a larger bore diameter, which will result
in higher pedal pressure when used without boost.
For example, the difference between a Chrysler 15/16" bore and 1-1/32" bore
MC is the difference between one-foot and two-footed braking, when used in
an unboosted disc brake system. The MCs are externally identical.
