A spring brake cylinder (100) for a brake system (800) of a motor vehicle (1000) includes a brake release mechanism (110), configured to axially contract a brake spring chamber (112) against a brake spring force in a release direction (RD) from a parking position (PP) to a driving position (PD). A brake state indicator (120) includes an actuation element (128) axially held in a force equilibrium (EF) between an actuation spring (124), exerting an actuation force (FA) on the actuation element (128), and a return spring (126), exerting a return force (FR) on the actuation element (128). The actuation force (FA) is altered by nut motion (MN) of a running nut (122), caused by rotational motion of a release screw (132) to shift the force equilibrium (FE), resulting in an axial movement (ME) of an actuation element (128) operatively coupled to an indicator pin (134) of the brake state indicator (120).
