Abstract

A hydraulic main brake cylinder, preferably having an electro-mechanical brake booster for a brake assembly of a vehicle is disclosed. The main brake cylinder is provided with two pressure rod pistons, preferably nesting within each other, one of which is actuated by muscle power, and the other one is actuated by the brake booster. Furthermore, an energy store is provided, which stores energy when the main brake cylinder is released and then transferred to the main brake cylinder upon the actuation thereof, thus supporting the operation of the main brake cylinder.
