Abstract

A brake system may include an actuation device, in particular a brake pedal, a first piston-cylinder unit with two pistons, in particular an auxiliary piston and a second piston, in order to supply a pressure medium to brake circuits via a valve device. One of the pistons, in particular the auxiliary piston, can be actuated by means of the actuation device. The brake system may further include a second piston-cylinder unit with an electric motor-powered drive, a transmission, and at least one piston to supply a pressure medium to at least one of the brake circuits via a valve device and a motor-pump unit with a valve device to supply a pressure medium to the brake circuits. According to one aspect, a hydraulic travel simulator is connected to a pressure or working chamber of the first piston-cylinder unit.
