Provided is a shim structure adapted to be interposed between a friction member and a forcing member configured to urge the friction member against a rotating member of a brake system. The shim structure includes a sheet member having opposing first and second surfaces defining a substantially uniform thickness of sufficient magnitude to not deform during urging of the friction member. There is no viscoelastic layer on the first or second surfaces. The first and second surfaces also define a waveform cross-section having an amplitude and a wavelength extending substantially the entire length of the sheet member; the amplitude and wavelength are of sufficient ratio to provide selective noise and vibration damping, isolation, and thermal dissipation for the brake system. Additionally, the amplitude and wavelength are configured to be variably tunable, providing different predetermined levels of noise and vibration absorption and attenuation. The wave-form cross-section is preferably sinusoidal.
