Abstract
A mechanical component has a recess for receiving a ceramic insert. The insert is held in the recess by a retainer member which preferably resiliently biases the insert inwardly into the recess. The insert provides a hardened bearing surface for the associated mechanical component. For example, the mechanical component may be a piston for use in an engine brake (especially as a master piston in the engine brake), and the ceramic insert may be the portion of the piston assembly which contacts a moving part of the internal combustion engine with which the engine brake is used.
