Abstract

The device comprises a brake cylinder with cylinder housing (3) with a casing wall (22) and at least one gable (23) and a pressure spring (5) positioned between the spring {4) and the gable (23) of the cylinder housing for activating the parking brake by mechanically influencing the piston (4) of the brake cylinder and a bar (11) which is axially displaceable relative to the release screw (1) in a through-bore (34) in the release screw (1). The bar (22) at a first end, within the cylinder housing (3), has a position sensing body (8,16) which is axially fixed to the bar (11) and provided with a contact surface (40) for contact against the nut (7). The second end the bar (11) has an indication body (12) which visibly protrudes out of the screw head (36) of the release screw (1) in case of axial displacement of the bar (11). This occurs due to axial displacement of the nut (7) from its outer end position, and of the contact surface of the position sensing body (8,16) which surface is in contact with the nut, during rotation of the release screw (10) for mechanical release of the parking brake.
