A brake actuation unit (1) having a master brake cylinder (2) and a pressure-medium reservoir (4); a pressure provision device (5), having a piston (51) actuated by an electric motor (35), wherein the piston delimits a pressure chamber (50); first and second groups of electrically actuatable valves (6a-6d, 7a-7d); and an electronic control unit (12, 12′). The electric motor has at least two independently operable drive units, each having at least one winding, for driving the electric motor. The electronic control unit has a first microcontroller (201) and a second microcontroller (301). The first microcontroller controls (205) one of the drive units and the second microcontroller controls (305) the other of the drive units. The first and second microcontrollers control (207, 307) the second group of valves.
