摘要

The invention relates to a brake actuation unit for motor vehicles, comprising a brake master cylinder, a booster stage connected in front of the brake master cylinder and a drive unit for driving the booster stage. According to the invention, to permit convenient braking manoeuvres, the transmission of both the actuation force and the booster force on the main piston (11) of the master brake cylinder (1) is achieved by a force transmission module (9) that has at least one elastic element (8) and that is situated in the main piston (11).
