The invention relates to a brake actuation unit (1) comprising a master brake cylinder (2) and a pressure-medium reservoir (4); a pressure provision device (5), the piston (51) of which can be actuated by an electric motor (35), wherein the piston delimits a pressure chamber (50); a first group of electrically actuatable valves (6a-6d, 7a-7d); a second group of electrically actuatable valves (23a, 23b, 26a, 26b); and an electronic open-loop and closed-loop control unit (12, 12'). The electric motor has at least two drive units operable independently of one another, each having at least one winding, for driving the rotor of the electric motor. The electronic open-loop and closed-loop control unit comprises a first microcontroller (201) and a second microcontroller (301). The first microcontroller is designed to control (205) one of the drive units of the electric motor and the second microcontroller is designed to control (305) the other of the drive units of the electric motor, and the first and second microcontrollers are designed to control (207, 307) the second group of valves.
