Holographic interferometry is used for the analysis of a self excited brake system mounted on a test rig. The technique developed for determining the fundamental vibrational characteristics of a noisy brake system is discussed. Interferograms of the noisy brake are recorded using a double pulsed laser arranged so that it can be triggered by four different methods, manual, rotational position of the disc, noise initiation and surface strain of the disc. Large mirrors allow for three orthogonal views of the system to be recorded simultaneously and smaller inset mirrors allow for additional discrete areas of the back of the system to be recorded along with the other images. Reconstructed images are shown of the modes of vibration over a typical noisy cycle. Mechanical measurements of disc surface strain input torque, finger and piston pad deflections and noise are illustrated throughout a complete disc rotation. This information complements that contained within the visual images.
