Abstract

A brake apparatus () and method of operating the apparatus are disclosed. The apparatus () has a plurality of brake elements () with a combined thickness of Y. At least one of the brake elements () has a wear portion () for tribological interaction with a wear portion () of an adjacent element () and is formed in two separable parts () having thicknesses Aand A. The method includes operating an actuator () at an actuation extension length less than a maximum actuation extension length to cause the wear portions () of the brake elements () to tribologically engage and thereby wear. This tribological engagement is such that as the elements () wear to a combined thickness of less than Y the extension length of the actuator is increased. A spacer () is inserted between the two parts () of the brake element () to cause the wear portions () to be tribologically engagable at a actuation extension length less than the increased actuation extension length.
