Brake shim and method thereof

A brake assembly for a motorized vehicle having at least one wheel, the brake assembly comprising:

• a rotating member rotatably mounted with respect to the at least one wheel and operable to transmit braking forces thereto;
• a housing member operatively mounted proximate to said rotating member;
• at least one friction member operatively disposed within said housing member and configured to frictionally engage said rotating member;
• an urging member operatively disposed within said housing member and configured to selectively effect the frictional engagement between said at least one friction member and said rotating member;
• a shim member interposed between said at least one friction member and said urging member, wherein said shim member is a unitary sheet member having a substantially-rectangular, non-flat plate with a first surface substantially opposing a second surface, said first and second surfaces defining a sinusoidal waveform cross-section having a substantially uniform thickness;
• wherein said sheet member is composed of one of a cold rolled steel, hot dipped galvanized steel, stainless steel and aluminum;
• wherein said waveform cross-section is a repeating, propagating geometric shape having a plurality of peaks and valleys;
• wherein said thickness is of sufficient magnitude so as not to permanently deform during urging of the friction member against the rotating member;
• wherein said thickness is between 0.3 and 1.5 mm;
• and
• wherein said waveform cross-section includes a selectively tunable amplitude configured to provide different predetermined levels of absorption and attenuation of induced vibrations and noise in the brake system.
