The invention relates to a pneumatic service brake actuator (1) for a brake system (100) of a vehicle, in particular of a commercial vehicle, the brake actuator (1) comprising a push rod (12) that is configured to transfer a braking force to a brake mechanism (101) of the brake system (100), a first service brake chamber (3) that is configured to receive pressurized air, a first piston head (19) that is operatively coupled to the push rod (12) and configured to move the push rod (12) from a retracted position (R) towards an extended position (E) along a push rod axis (X) when pressurized, and a second service brake chamber (5) that is configured to receive pressurized air, a second piston head (37) operatively coupled to the push rod (12) and also configured to move the push rod (12) from the retracted position (R) towards the extended position (E) when pressurized, wherein the first and second service brake chambers (3, 5) are arranged to act pneumatically parallel to one another. It is suggested that the first piston head (19) and the second piston head (37) slidingly and sealingly engage a corresponding first side wall (27) and second side wall (51) of their respective first and second service brake chamber (3, 5).
