A brake assembly includes a rotor and at least one backplate supporting a brake pad for frictionally engaging the rotor for braking. A sheet metal plate is operatively connected to the back plate. The sheet metal plate has a groove cut therethrough to form at least one tuning fork member. A damping material is engaged with the at least one tuning fork member for damping energy associated with vibrations of the tuning fork member, thereby sound-dampening brake squeal noise.

A measurement system (10) for accurately measuring the surface geometry of a part in three dimensions includes a laser (22) for emitting a laser beam (20). An objective lens (18) receives the laser beam (20) and expands the received laser beam (20) into a diverged beam. A liquid crystal system (16) is disposed in front of the objective lens (18) with respect to the laser (22) for receiving the diverged beam. The liquid crystal system (16) receives the diverged beam and generates at least one fringe pattern (24) on a surface of a three dimensional part which is to be measured. A computer (12) is in communication with the liquid crystal system (16) to control the pitch and phase of the fringe pattern (24).
