Abstract: A latching mechanism for a brake actuator is provided. The latching mechanism comprising an annular flange and a plurality of resilient elements extending radially inwardly from the annular flange. Each of the plurality of resilient elements comprises a U-shaped cross-section and a tooth on a radially inner end. The tooth is configured to conform to and engage with ratchet teeth of a wear compensation sleeve of a brake actuator.

Abstract: A torque limiting assembly is disclosed comprising: an input shaft; an output shaft; and spring having a first end coupled to the input shaft and a second end coupled with the output shaft. In a low torque mode, when the input shaft is rotated the spring is compressed by a low amount and transmits a force to drive rotation of the output shaft, whereas in a high torque mode the spring is compressed by a high amount such that the input shaft rotates relative to the output shaft. This relative rotation moves or urges an engagement member so as to either: disconnect the input shaft from the output shaft; or engage a housing to prevent or inhibit rotation of the input shaft relative to the housing.

Abstract: The present application relates to a piston assembly for engaging two selectively engageable parts. The piston assembly has a housing defining a piston cylinder and a piston. The assembly also has a piston stroke limiter. The piston stroke limiter is configured to limit the length of a return stroke of the piston from an extended stroke position and a retracted stroke position. A crushable body acts between the piston and the piston stroke limiter and is arranged to reduce in axial length when a length of an extended stroke exceeds a length of a retraction stroke to maintain the length of the return stroke.
