An apparatus, system, and method according to which a bellcrank is used to transfer an output of a lever to a component requiring actuation. For example, a bellcrank that includes two interlocking portions transfers an output of a linear motion around a fixed axis via a rotational motion then to a transverse motion in order to pressurize brake fluid in a master cylinder of a vehicle.
