The invention relates to a brake actuator (1) for a vehicle, in particular for a commercial vehicle, comprising a housing (3) having a push rod aperture (5), a push rod (7) configured to connect to a brake mechanism (101). The push rod (7) is configured to move back and forth through the push rod aperture (5) between a retracted position and an extended position. A sealing boot (13) extends along the push rod, being flexible in a longitudinal direction (L) and having a first end portion (15) sealingly engaging the push rod (7) at an intermediate region (8) of the push rod (7), and a second end portion (17) sealingly engaging the push-rod aperture (5). The boot (13) has a plurality of outer folds (19a, 19b, 21) distributed along the longitudinal direction (L). The boot (13) is configured to resiliently deform between a relaxed state and a loaded state, the relaxed state corresponding to the retracted position of the push rod (7) and the loaded state corresponding to the extended position of the push rod (7). It is suggested that the first end portion (15) of the boot (13) comprises a stop shoulder (27) arranged inside the housing (3). The plurality of outer folds (19a, 19b, 21) comprises at least one first outer fold (19a, 19b) configured to abut against the stop shoulder (27) inside the housing (3) when the push rod (7) is in the extended position, and at least one second outer fold (21) configured to evert past the stop shoulder (27) to the outside of the housing (3) when the push rod (7) is in the extended position.
