1. A latching mechanism for a brake actuator, the latching mechanism comprising:
an annular flange; and
a plurality of resilient elements extending radially inwardly from the annular flange, wherein each of the plurality of resilient elements comprises a U-shaped cross-section and a tooth on a radially inner end, wherein each of the plurality of resilient elements comprises a radially inner leg and a radially outer leg joined by a curved base, wherein the radially inner leg is longer in length than the radially outer leg, wherein the radially inner leg and the radially outer leg of each resilient element of the plurality of resilient elements extend axially and are substantially parallel to each other thus forming the U-shaped cross section, wherein the tooth of each resilient element of the plurality of resilient elements is disposed at an axial end of the radially inner leg opposite the curved base, and wherein the tooth of each resilient element of the plurality of resilient elements is shaped to conform to and engage with ratchet teeth of a wear compensation sleeve of the brake actuator such that, in use, in response to a force biasing the wear compensation sleeve in a first axial direction, driving engagement between the ratchet teeth and the tooth urges the radially inner leg radially outwards causing the curved base to bend and thus allowing the wear compensation sleeve to move forward in the first axial direction, and in response to a force biasing the wear compensation sleeve in an opposing second axial direction, engagement between the tooth and the ratchet teeth does not cause the radially inner leg to be urged outwards and the tooth prevents the sleeve from moving back in the second axial direction.
