Brake adjuster mechanism

A method of operating a brake having a brake adjuster mechanism that includes:

• an input shaft,
• a one-way clutch, and
• a torque limiting clutch,
• the input shaft being coupled to an input element of the torque limiting clutch,
• the one-way clutch being coupled to the torque limiting clutch,
• the torque limiting clutch further including an output element and a coupling portion, the coupling portion including a projection for selectively rotationally coupling the input element and the output element, one of the input element and output element including a first recess circumferentially spaced from a second recess,
• the projection being selectively biased into the first recess and said second recess,
• the brake adjuster mechanism including a land between the first recess and second recess;
• and
• wherein the method includes the steps of:
• positioning the projection in the first recess,
• then applying the brake so as to rotate the input element relative to the output element thereby removing the projection from said first recess and positioning the projection on the land,
• then releasing the brake whilst ensuring the projection remains on the land, and
• then applying the brake whilst the projection is on the land so as to rotate the input element relative to the output element thereby moving the projection from the land into the second recess.
