Abstract: A brake unit for utility vehicles includes a carrier unit and a transmission element. The carrier unit has a guide section in which the transmission element can be arranged such that the transmission element can be moved along a guide axis. The transmission element includes a first receiving section, which can be engaged with a piston rod of a brake cylinder, and a second receiving section, which can be engaged with a tappet of a wedge unit. The transmission element is configured to transfer forces and transfers along the guide axis between the piston rod and the tappet.
