The invention relates to a pneumatic brake actuator (4) for a vehicle, in particular a commercial vehicle, comprising an actuator housing (6) having a pressure chamber (8) and a piston chamber (10), a piston (12) that is mounted inside the piston chamber (10) and configured to reciprocatingly move between a retained position (14) and an extended position (16) as a function of pressure inside the pressure chamber (8), a piston rod (18) connected to the piston (12), wherein said piston rod (18) is guided through the actuator housing (6) via a rod opening (20), a compression spring (22) being effective to push the piston (12) towards the retained position (14), and a rod boot (24) for sealing the rod opening (20), wherein said rod boot (24) is connected to the rod opening (20) and the piston rod (18), said rod boot (24) comprising a mantle (30), said mantle (30) having a first section (34) and a second section (36) opposite from the first section (34), and wherein the first section (34) is connected to the rod opening (20) and the second section (36) is connected to a mounting section (38) of the piston rod (18).According to the invention, the second section (36) is inverted inwardly (40) relative to the first section (34), wherein a longitudinal dimension (I1) of the first section (34) and a longitudinal dimension (I2) of the second section (36) vary with respect to each other as a function of a relative position of the first section (34) to the second section (36).
