Abstract
A brake system is described with a master cylinder actuated by a control rod connected to a plunger piston and an actuator piston acting directly on the primary piston. A hydraulic reaction piston is housed in the piston so it can be subjected to the pressure of the primary chamber and to the opposing action of a reaction spring. The plunger piston can push the reaction piston directly to push the master cylinder.
